Permit No. WQ0035784
Engineer's Evaluation of Valve Installation Including Specifications &
Calculations
Dear Ms. Plummer:
Brooks Engineering Associates, P.A. (BEA) is providing supporting engineering
documents associated with the Additional Information Request for the Minor
Modification to Permit No. WQ0035784. This letter is to serve as the amendment to the
Specifications and the Calculations. Enclosed are amendments to the affected
engineering plan sheets.
This project involves the evaluation of a valve installation on the equalization tank at the
Cottages of Boone wastewater treatment facility as part of a permit modification. The
valve is replacing the equalization pumps that were originally designed and installed.
Additionally, a 90% outlet pipe is to be installed on the EQ tank.
The equalization tank was originally designed with a pump to transfer raw influent to the
drum screen filter. The pump was controlled by the PLC control system that operates the
entire plant. The pump fed the drum screening unit at the head of the plant and activation
was controlled by the level in the drum screen effluent tank. A pressure transducer in the
drum screen tank provides water level readings to the PLC system that activates the feed
pump when the water level in the drum screen effluent tank was at a prescribed low level
(20%) and shut the pump off at the prescribed high level (60%). Effluent in the drum
screen tank is pumped to the initial anoxic treatment tanks by a separate triplex skid
pump system.
Currently installed is an air actuated Orbinox (model 20-3636R) slide gate valve (see
spec sheet attached). The valve is actuated by the PLC system in the same way the pump
system was actuated so there is no change to the function being provided. The low and
high water levels in drum screen tank are communicated to the PLC by a pressure
transducer. In a low level condition the PCL actuates an air control solenoid valve
opening a 3/8" air line to the pneumatic motor on the knife gate valve, closes the air valve
at the high water condition. The air supply is from the overall plant air compressors.

The change from the pumps to the valve result in two condition changes. First, the flow
rate in to the drum screen is higher than the pumps. The original pumps were rated for 70
gpm. The outlet of the equalization tank is still 2" so the flow rate with a 90% full tank
(worst case:18.8' head on 1.913" orifice) would be 187 gpm. The result is simply that the
time to fill the drum tank to a high shut-off level is significantly less with the valve
versus the pumps, but that has not negatively affected the operation of the drum screen or
the plant as it has been operating with the valve control for over a year.
Second, the equalization tank has effectively less storage. The revised net tank storage is
40,787 gallons, which is still well above the minimum design requirements of 25% of the
daily design flow for EQ storage.
In addition to the valve installation, a 90% outlet pipe is to be installed on the
equalization tank. This is an exterior tank piping that would allow water pumped in to
the tank to flow directly to the wastewater treatment system if it reached a 90% full level.
The engineering plans call for the installation of a 2" stainless steel flange connection
(304 SS) to be welded on to the existing tank (in accordance with ANSFAWS D1.6:1999
welding code), connecting to a schedule 80 flange and piping (ASTM D 1785) routed
down the tank exterior to the ground for support. The schedule 80 piping is to be
supported by stainless steel pipe backets (304 SS) welded to the tank. At the ground the
piping is to be supported by a 4" thick concrete pad with a 1/4" rubber mat for abrasion
resistance. The piping is to be fitted with a drain directed to the influent pump tank to be
able to drain after use. The line is to connect back into the EQ tank after the control gate
valve (above). Once installed the piping and connections are to be hydraulically tested
by a static water level test. The piping is to be filled from the drain line up to the tank
connection (with all valving to other tanks closed). The water level shall be allowed to
equilibrate with the water level at or above the invert at the top connection for 2 hours.
The piping and joints shall be inspected for leaks.
BEA appreciates the opportunity to provide engineering consultation on this project.
Please feel free to call with any question at [phone].
Sincerely,
Brooks Engineering Associates, P.A.

Safety Notes:
WARNING!
Pumps used in this system start and stop automatically during normal operation. Always stop
the drive unit before beginning any repair work on it. Make sure that the motor cannot
accidentally be started by any means during repairs. Refer to individual manufacturers'
instruction manuals (see separate binder) for more specific information.
Failure to follow the above procedure may result in personal injury and/or property
damage!
WARNING!
Chemical metering pumps and feeders that convey hazardous media must be decontaminated
prior to any maintenance work on them. Refer to individual manufacturers' instruction manuals
(see separate binder) for more specific information.
Failure to follow the above procedure may result in personal injury and/or property
damage!
WARNING!
Cleaning and pH adjusting chemicals used in this installation may be harmful. Manufacturer's
material safety data sheets (MSDS) and handling instructions should always be followed. Use
eye and skin protection when handling chemicals.
Failure to follow the above procedure may result in personal injury and/or property
damage!

Precautions
• No silicone -containing agents are to be introduced into the system. Use of these materials
in any quantity will cause irreversible membrane fouling.
NOTE: Antifreeze and defoamers may contain silicone and should therefore never be
allowed into the system.
• Refer to Appendix A. System Specifications for maximum temperature to which the
standard membrane elements should be subjected. Do not exceed this temperature or
irreversible damage can occur.
• Refer to Appendix A. System Specifications for the pH range over which the membranes
maybe subjected during normal operations, and during cleaning.
• The system must be protected from freezing. Failure to do so will cause damage to the
membrane elements and will cause damage to other system components.
• Membrane elements should never be allowed to dry out. At all times the membrane
elements must remain wet. Damage from membrane dry out is irreversible.
• Do not process any solvents or chemicals harmful to the membranes. Consult factory
prior to introducing any solvent.
• Abnormal concentrations of strong oxidizers (chlorine, hydrogen peroxide, etc.) must not
be present in process water on a continuous basis. Consult factory for allowable
concentrations.
• Coarse or abrasive particles should be prevented from entering the system, since they
may damage system components. A 1/8-inch screen in the process pump suction line (by
others) generally provides sufficient protection.

Water Quality Guidelines
-9-
• Incoming water quality (process water) will affect membrane performance. High water
hardness is often identified as a major source of excessive membrane fouling.
• Water containing salts of hardness or other sparingly soluble salts must not be used for
cleaning membranes. Soft or deionized water must be used. Both hot and cold water
supplies to the cleaning tank must contain less than 3 grains of hardness (51 parts per
million (ppm) of CaCO3).
Note: We do not recommend the use of permeate for either cleaning of the membrane
system.
• Iron, aluminum, and manganese in cleaning water will reduce the performance of the
cleaning solution. Generally, iron concentrations should be less than 0.3 ppm, aluminum
less than 1 ppm, and manganese less than 0.05 ppm.
• At no time during process operations should the pH of process fluid be below pH 3.0 or
above pH 11.0. Operation outside of these parameters will compromise membrane life.
Silica compounds naturally occur in many waters. Please check your water source for the compounds
listed in the table below:

Membrane Preservation and Storage
All membranes are shipped with small amounts of deionized water and a preservative.
Modules can be initially stored in a sheltered area, protected from freezing and sealed as shipped
until ready for use. Do not allow the membranes to dry out.
After installation, the elements must be preserved, as recommended below, if the system must
be shutdown.
Short -Term Shutdown: Less Than 8 Hours
The Dynalift system drains and backwashes at every shutdown. It is safe to leave it this
condition for up to 8 hours. The membranes will be filled only on the permeate and will slowly
permeate out much of the water until the membranes are dry.
Intermediate Shutdown: Less than 1 Week
If the Dynalift system is to be shut down for an extended period it MUST be kept filled to
prevent drying out. It must be cleaned using the standard cleaning process before refilling with
potable water. The manual drain valve should be closed to prevent loss of the water due to a
power failure. The system can then be filled from the chemical feed system potable water valve

Long -Term Shutdown: More Than I Week

Controls
PLC Controls
All controls are located in the Motor Control Center (MCC) and the attached Main Control
Panel (MCP) section. The MCP section houses the programmable logic controller (PLC), and
associated I/O components for the MCC motor controls. All other skids and sub -systems are
controlled via Ethernet remote I/O panels located on each skid, or near the instrumentation. The
PLC performs all the logic required for the automatic operation of the components. The
Human/Machine Interface (HMI) panel provides all control and status for the entire system. The
workstation is installed in the door of the Main Control Panel. Specific operation of the PLC
program is described in the Appendices for this job. User manuals for the individual controls are
enclosed in the Manufacturer's literature section of this manual.

Operation
The following is a general description of the wastewater treatment process based on the
Dynalift MBR system.
The effluent from the Equalization Tank is processed through a series of treatment units prior
to being discharged as reuse water. The process can be broken down into the following steps:
1. Solids Separation — The wastewater from the Equalization Tank pump passes through a
rotary brush screen with a Imm mesh to remove large solids. The solids removed are directed
back to the sewer. The brush screen is equipped with an intermittent water flush on the
discharge chute to prevent solids from building up there. The screen and the holding tank
beneath it have large overflow pipes to prevent any possibility of an overflow out of the
screen. In addition the sludge wasting back to the sewer is directed into the screen discharge
to help flush solids to the sewer. Three transfer pumps, one for each biological train and a
common installed spare, located outside the screen room, send the filtrate to the Anoxic
Tanks for each train.
2. Anoxic Zone — Wastewater from the transfer pumps flows into the Anoxic Tanks and mixes
with the mixed liquor circulating in the system. A mix/recycle pump recirculates the mixed
liquor through a circular slot at the bottom of the tank. The high velocity flow sweeps the
bottom from the center out and causes circulation up the side of the tank and down through
the center again. A proportioning valve in the pump suction allows sludge from the Aeration
tank to be returned to the anoxic zone bringing the Nitrates produced by oxidation back into
the anoxic tank. The anoxic tank is kept in a low oxygen condition. Bacteria in the
wastewater are starved for oxygen so they break down the Nitrates (NO3) to get the oxygen
they need. This process releases Nitrogen into the air. The tank is sealed and vented to the
outside of the building. The anoxic zone is also provided with a supplemental carbon feed to
provide a food source for the bacteria for low flow conditions, or if not enough BOD is
available.
3. Aerobic Zone — Most of the mixed liquor returns directly from the membranes into the
Bioreactor. The mixed liquor passing through the Anoxic tank also overflows into the
Bioreactor. Most of the aeration for the bioreactor comes from the air introduced into the
membranes. DO control is provided by a DO sensor and additional aeration of the
bioreactor. Aeration is by cylindrical EPDM fine bubble diffusers radiating from a common
header at the center of the tank. The design is such that maintenance of the diffusers can be
performed from the top of the tank without entering the tank.
4. Membrane Separation — The mixed liquor is circulated from the bioreactor through the
membrane skids and returning into the Anoxic Tank and Bioreactor by a low head centrifugal
pump. The membranes are a tubular style consisting of many small tubes contained in a
number of 8" diameter PVC housings. The mixed liquor flows inside of all of the small
tubes and clean water permeates through the walls of the tubing into the outer shell. A pump
on each membrane skid collects the permeate and sends it into the common backwash tank.

www.dynatecsystems.com

Operations and Maintenance Manual Ultrafilter Wastewater Treatment System -13
An air diffuser at the bottom of each membrane module introduces air into the mixed liquor
to cause turbulence which helps scour the membrane surfaces to reduce fouling.
5. Backwash System — The permeate in the backwash tank goes out through an overflow pipe to
the qualitative instrumentation final UV disinfection system. Permeate is stored in the tank
to be used periodically to backwash the membrane to prevent fouling. After a set number of
backwashes a flush is also performed. During the flush the mixed liquor in the membranes is
pumped back into the bioreactor a backwash is performed along with water flushing of the
air diffusers at the bottom of each membrane. If sludge wasting is enabled then some mixed
liquor will also be diverted back to the sewer.
6. Chemical Cleaning — Occasionally the membranes need to be chemically cleaned to remove
scaling and other foulants that regular backwashing cannot remove. This process is
completely automatic, except for filling the chemical tanks, and is initiated by the operator.
The Dynalift to be cleaned is first stopped, which always initiated an extended backwash.
Then the operator presses the cleaning button and the system cycles through a multi -step
process of draining, filling, adding chemical, refreshing chemical, and then performing a
second cleaning with a different chemical. A button on the HMI allows the operator to
determine whether the membrane skid goes back on line automatically at the end of a
cleaning cycle, or simply sits empty in a cleaned condition. Note that if it is to remain off for
more than 8 hours or so it should at the very least be filled with potable water and not left
dry.
7. Final Disinfection — The permeate discharge passes through an enclosed UV (Ultraviolet)
light disinfection unit then out to discharge. This UV is nothing more than a backup safety
system as Ultrafiltration membranes have pores that are too small for bacteria or viruses to
pass through. So unless there is a serious membrane breach there is nothing for it to kill.
Note that in this system qualitative instrumentation has been installed upstream of the final
UV that the operator can use to determine whether the water produces is suitable for reuse.

Membrane Cleaning
Introduction
The early establishment of an effective cleaning regime for the membrane is fundamental to
the long-term successful operation of the treatment system. If successful cleanings are not carried
out when the system is new and maintained over the life of the system, the system will not
operate to satisfactory performance. In addition, cleaning will be required more frequently.
When Cleaning is Required
There are two occasions when a cleaning cycle should be carried out.
1. When TMP has risen to the point which has been determined to indicate the system is
excessively fouled. This TMP value will be different for every jobsite, as it is based on
the characteristics of the wastewater, and not the performance of the membrane.
2. Whenever the system will be shut down for more than a few hours.
Types of Fouling
There are two basic types of fouling that may normally occur:
1. Organic, where typically oil or other organic material has fouled the membrane by
causing a gel layer to form on the surface of the membrane, preventing or slowing the
flow of water through the membrane.
2. Inorganic, where salts and/or metals are present in the waste, or have precipitated in the
waste, and have plugged the pore structure of the membrane, reducing permeate flow.
Automatic Cleaning Process
This system features an Automatic Cleaning process that is initiated by the operator. The
operator starts the process by first pressing the Stop button for the Dynalift A or B, to be cleaned.
Then the operator presses the Clean button, which sends you to the Cleaning Screen
Pressing the Start touch button on the cleaning screen begins the automated process. The steps in
this process are as follows:
1. If the backwash tank is not filled then the Potable Water Valve opens and fills the Cleaning
Tank with potable water to the Full Level.
2. The Membrane Drain Valve closes and the membrane skid fills Pump starts to circulate water
through the membranes to flush out any remaining mixed liquor. The Cleaning Pump stops
and the Membrane Drain Valve again opens and allows the membranes to drain for a time
period. Then the Cleaning Pump restarts to remove the last of the dirty water from the
cleaning tank.

3. The Backwash Tank fills with water from the potable water source, and permeate from the
other Dynalift if it is in operation. If this process takes too long (greater than 30 minutes), an
alarm sounds, the operator is shown the failed step number, and the cleaning process aborts.
4. The normal backwashes for both Dynalifts are inhibited. The appropriate Dynalift drain
valve opens, the backwash valve opens, and a long backwash occurs until the Backwash
Tank has reached the Reuse Low Level. If this process takes too long (greater than 30
minutes), an alarm sounds, the operator is shown the failed step number, and the cleaning
process aborts.
5. Repeat step 1 (fill backwash tank).
6. Repeat step 2 (backwash).
7. The Bleach Valve opens and fills the cleaning tank with the bleach solution. If this process
takes too long, an alarm sounds, the operator is shown the failed step number, and the
cleaning process aborts.
8. The Cleaning Pump starts and bleach is circulated through the membranes for the specified
cleaning time. During this time the Backwash Tank is also being refilled. During the
circulation the Membrane Air Valve opens briefly at the specified intervals and for the
specified length of time to provide additional agitation. If the level in the Cleaning Tank
should drop too low an alarm will sound, and the operator will be shown the failed step
number, and the cleaning process will abort.
9. Stop the Cleaning Pump and open the Membrane Drain Valve and drain the Dynalift
completely for a timed period. Then restart the Cleaning Pump to remove all the bleach
solution.
10. Inhibit the normal backwashes and backwash the Dynalift to drain until the Backwash Tank
reaches the Reuse Low Level point.
11. Refill the Backwash tank with potable water and permeate if the other Dynalift is running.
12. Open the Clean Water Valve and fill the cleaning tank to the Flush Level. Start the Cleaning
Pump and pump the contents of the cleaning tank to drain.
13. The Citric Valve opens and fills the Cleaning Tank with the citric solution. If this process
takes too long, an alarm sounds, the operator is shown the failed step number, and the
cleaning process aborts.
14. The Cleaning Pump starts and citric solution is circulated through the membranes for the
specified cleaning time. During this time the Backwash Tank is also being refilled. During
the circulation the Membrane Air Valve opens briefly at the specified intervals and for the
specified length of time to provide additional agitation. If the level in the Cleaning Tank
should drop too low an alarm will sound, and the operator will be shown the failed step
number, and the cleaning process will abort.
15. The Cleaning Pump stops and the Membrane Drain Valve opens to drain the cleaning
solution out completely. Then the Cleaning Pump restarts to drain the rest of the Cleaning
Tank.

16. The normal backwashes for both Dynalifts are inhibited. The appropriate Dynalift drain
valve opens, the backwash valve opens, and a long backwash occurs until the Backwash
Tank has reached the Reuse Low Level. If this process takes too long (greater than 30
minutes), an alarm sounds, the operator is shown the failed step number, and the cleaning
process aborts.
17. Repeat step 1 (fill backwash tank).
18. Repeat step 16 (backwash).
19. Open the Clean Water Valve and fill the Cleaning Tank to the Flush Level. Start the
Cleaning Pump and pump the contents of the cleaning tank to drain.
20. Show the operator that the cleaning was successful, and indicate that the manual valves ALL
need to be returned to their normal positions before starting the system.
Change the manual valves for the Dynalift that was cleaned.
a. For Dynalift A
i. Throttle V 107, V 108 as required
ii. Open V603
iii. Close V 109, V602
b. For Dynalift B
i. Throttle V207, V208 as required
ii. Open V703
iii. Close V209, V702
Cleaning Time
The time that a cleaning procedure is left to run depends on the process being carried out.
Water temperature plays a large part in the time required for a successful cleaning. It may be
necessary to increase cleaning times during cold weather. Additional cleaning time beyond two
hours or so is usually not very helpful for Chlorine or Caustic cleaning. Additional cleaning time
may very helpful for acid cleaning when trying to remove scaling. Overnight is a very good idea
if possible.

Cleaning Solutions
Warning. Most of the chemicals listed are hazardous in some way. ALWAYS, carefully
observe the manufacturers recommendations, and take appropriate safety steps such as
the use ofgloves, goggles, protective clothing, etc.
Always follow the recommended concentrations and other directions for each chemical found
later in this chapter.
There are a wide variety of cleaning chemicals available, but the most commonly used are the
following:
Cleaning Chemicals
Memcleen A
This acidic wash chemical is used to remove scaling from the membrane.
Note: Memcleen A is a mild acid and as such care should be taken in handling, using
gloves and safety glasses where appropriate
Chemical Calculation:
sired Memcleen A Concentration % by volume) = Injector Ratio
100 Setting
Example: Recommended Memcleen rate is 3%, then the calculation is as follows:
= 33.33 = 33:1
100
Chlorine
This wash procedure is used to remove stubborn organic material.
Ensure that the chemicals are measured accurately or membrane damage could occur.
Do not exceed five hundred parts per million (500 PPM) total Chlorine.
Note. Sodium hypochlorite is an extremely strong oxidizer and as such care should be
taken in handling, using gloves and safety glasses where appropriate

Appendix B. Operator Interface Screens
This chapter describes the Human/Machine Interface (HMI) as supplied with this project. This
installation has one touch screen HMI which controls both trains.
CAUTION. When looking at the HMI you must be very careful not to accidently push
any buttons that start or stop processes or change set points In the case of set points if
you suddenly find yourself at a screen asking for a numerical input ALWAYS PRESS
CANCEL TO EXIT I
SYSTEM OPERATIONAL HMI SCREENS
The following HMI screens are used to control the common operations of the Dynalift System
shared by membranes A & B. These include the screen, waste transfer pumps, blowers,
backwash pumps, reuse pump, and chemical feed skid.
All screens are touch screens and you should NEVER use anything but clean fingers to
operate the screen. Pencils and other objects will permanently damage the screen. When leaving
the system unattended it is a very good idea to always leave a screen showing which has a
pictorial view on it. These screens only have navigational buttons on them. Someone curiously
touching the screen will see it suddenly change, but no harm will be done. This is not true of
screens which have pushbuttons or set points.

The off line blower should always be shut down, it's filter cleaned, and fogged with oil
immediately to prevent seizing due to corrosion.
The blowers are controlled by the pressure transmitter located on the Process Air Header.
The blower speed is controlled by a VFD (variable frequency drive) such that the pressure in the
header remains constant at all times. Positive Displacement blowers have a minimum operational
speed due to lubrication issues. This means you may here the relief valves pop off when the
demand for air falls very low.
The indicators at the top of this screen show the current speed for each blower and the current
header pressure.
The pressure alarm set point buttons allow you to adjust the where the alarms occur. These
alarms have time delays on them that keep short term pressure changes from causing nuisance
alarms.
The manual speed set point buttons allow the blowers to be speed controlled while in the
Forced On mode. Blowers should NEVER be operated on line this way. All blowers must be
operated in Auto or damage may occur.

Figure 12. Blower PID Tuning
The speed of the blowers is controlled by a single PID loop. The Discharge Pressure Setpoint
button allows you the change the header pressure. Raising or lowering the discharge pressure
will immediately change the air flow to the membrane skids. A set point change requires
changing the globe valve opening to maintain 60 cfin to the membranes.
It is very important that the system have enough pressure to overcome the static head in the
membranes and the bioreactor, plus all pressure losses due to valves and piping etc. If there is
not enough pressure the flow to the membranes or bioreactors can suddenly stop, with a big risk
of plugging the membranes. Reducing air pressure to optimize energy efficiency can be very
risky and should only be done with very close monitoring.
The Kp, Ki, Kd, and DB set points control how the PID loop functions in controlling the
blower speed. PID loop tuning is more art than science. Adjusting these set points should be left
to someone skilled in the art of PID tuning.

pump is a spare for both the A and B Dynalifts. Pump A and Pump B can only be enabled for
Dynalift A and Dynalift B respectively. Pump S can be enabled for either Dynalift.
The status indicators show which automatic valves are opened or closed and which pumps are
running. The two pressure indicators show the suction pressure to each pump. Since the level in
the bioreactors varies over a range of just a few inches the pressure transmitters are a good
indicator of whether the strainers are fouled and are alarmed for that purpose.
Using the spare pump for either train A or train B requires the repositioning of multiple
manually operated valves.

Only one backwash pump is used at a time with the other one turned off. Manual valves
direct the flow through the appropriate pump. The Dynalifts are backwashed independently, and
can have different schedules. The PLC handles conflicts in the schedules automatically, by
inhibiting one or the other backwash briefly. The effluent transfer pumps operate from high and
low setpoints in the permeate tank. The 3-way valve AV-3006 in the discharge of the reuse
pumps normally directs permeate to the dosing tank. High level in the dosing tank will redirect
the permeate flow to the 14-day storage tank.

The set point buttons for Cleaning are common to both trains. The cleaning fill level set point
is used to set the bottom header pressure that correlates to the membranes being full of water or
chemicals. It is desirable to fill them until the permeate level is up into the tee at the top of the
membrane where you can no longer see it. Setting this value too high though will cause the
water or chemicals to overflow into the top header and the set point value will never be reached,
causing a cleaning alarm.

The empty level set point is used to determine that water or chemicals have been successfully
drained so the next step can proceed. It should be slightly above zero to reduce nuisance
problems.
The Maximum cleaning temperature only come into play if a very long cleaning is carried out
and the membrane heats up from flush pump energy. In the event the maximum temperature is
reached in any step the cleaning process will automatically proceed to the next step.
The Flush Pump Set Points control the operation of the flush pump only during cleaning.
Flush circulation time is used to ensure a thorough flush before moving to the next cleaning step.
The drain time is how long the pump can run when pumping water out of the membrane back
into the bioreactor.
The Chemicals Set Points control how long each chemical stays in the membrane. The
indicators also show how much time remains before the chemical step completes.
The final Backwash time sets how much backwashing is done after a chemical cleaning. Be
sure that the time is not so long that the low level in the backwash tank set point shuts down the
cleaning process and prevents it from completing!
The two duration indicators show the duration that the each chemical was in the membranes
during the previous cleaning, not this one.

3. FT1002A GPM — Current permeate flow rate from the A membrane skid. Note that is
gross flow, and the actual flow leaving the system is less because some permeate is
used for backwashes, diffuser flushing, and screen chute flushing.
4. FT1001A CFM — Air flow into the A membrane diffusers. This flow is set by the Red

at around the design flow of 60 CFM.
5. PT1001A PSI — Feed pressure to the bottom membrane header.
6. PT1002A PSI — Permeate pressure in the membranes
7. TMP PSI — Trans Membrane Pressure, the differential pressure across the membranes.
There is a mounting height correction applied so it will not exactly equal PT1001A-

The feed pressure set points on the left are critical to the safe operation of the membranes.
For this reason you have high and low warning alarms as well as high and low shutdown alarms.
The warning alarms should be set close to the normal operation values as possible without
causing nuisance alarms. The shutdown alarms should be set only a little higher and lower.
The TMP set points in the center are critical to the safe operation of the membranes. For this
reason you have high and low warning alarms as well as high and low shutdown alarms. The
warning alarms should be set close to the normal operation values as possible without causing
nuisance alarms. The shutdown alarms should be set only a little higher and lower.

The TMP offset value set point accounts for the mounting height difference between the Feed
pressure transmitter and the permeate pressure transmitter. TMP should read zero with the
membranes sitting partially filled with water.
Membrane Air flow is critical if it stays high or low for a long period of time (1 hour). Both of
these set points shut the train down if they are reached.
The permeate pump delay set point provides time for permeate flow to be established by
gravity flow alone before the permeate pump tries to increase the flow.
The flush pump run time set point is the maximum amount of time the flush pump can run in
the event it doesn't go off automatically by the pressure sensor indicating the membrane is
empty.
The low cutoff pressure set point is used to tell the flush pump the header is empty.
The Backwash Interval Timer set point sets the time between backwashes.
The Backwash Duration timer set point sets how long the backwash pump runs during each
backwash.
The Backwash Flush Counter set point determines how many backwashes will occur before
the flush step in added into the backwash sequence.
The Backwash Stop Duration timer set point allows a longer or shorter backwash to be used
whenever the train shuts down.
The Process Temperature High set point provides a warning if the mixed liquor is getting too
hot.
The Process Temperature Low set point provides a warning if the mixed liquor is getting too
cold for the biology to work correctly.
The Power Fail Auto Restart Button allows you choose whether the train auto -restarts after a
power failure or waits for the operator to restart it.

The sludge flow indicator shows the flow through the flow meter common to both trains.
Sludge totals from the flow meter are accumulated by the PLC separately for each train.
The start and stop buttons determine whether sludge wasting will occur each day. Once
started sludge wasting will start every day, unless stopped.
Sludge wasting starts each day at the time set on this screen. Some sludge is wasted during
each flush until the Desired Sludge Waste amount is reached. This reduces the impact on the
Biomass as only a small percentage of the total for each day is wasted at any one time.
There are two accumulator totals, one for the current day, and one for the total for this train.

The permeate pumps is driven by a VFD and the pump is controlled by a flow meter and PID
loop to operate at a constant flow rate, set by the flow set point on this screen.
The permeate pump is run against a constant restriction provided by a V-Port ball valve on the
pump discharge. Without this restriction the membrane would gravity permeate out at a rate
high than might be required. This valve must be carefully adjusted to provide a wide range of
flows over the normal operating speed of the pump.
The pump can be programmed to achieve three different permeate flow rates, depending on
the level in the Equalization Tank.

All the valves on these screens have an indicator to show whether they are open or closed.
Valves that have limit switches get this status from the limit switches. Valves that do not have
limit switches indicate whether they are in the energized position or not. If a valve with limit
switches is not either fully open or fully closed it will indicate an error.
Be sure to always return all valves to the correct operating mode (auto) before exiting from
this screen!
The Bioreactor Isolation valve is located at the bottom of the Bioreactor before the strainer. It
spring closes in the event of a power failure as a backup to the Membrane Feed Valve so that the
biomass is not accidentally lost into the sewer.
The Dynalift Feed Valve is located between the circulation pump and the membrane rack. It
is spring closed and held open during normal operation. During a flush dump cycle this valve
closes briefly while the membranes are drained. It operates typically once an hour.

The Concentrate Return Valve is held open during normal operation. It only closes during the
cleaning cycle to retain the cleaning chemicals in the membranes.
The Dynalift Drain Valve is a spring opened valve. It is normally held closed, and opens
during a power failure or when the system is stopped to drain the membranes. Note that a manual
valve is provided for long term shutdowns where you don't want a power failure draining the
preservative out of the membranes.
The Chemical Valve is normally closed and only opens during portions of the cleaning cycle
to allow chemicals or flush water to fill the membranes.
The Drain Flush valve is normally closed and opens briefly during the flush cycle to direct
mixed liquor from the flush pump back into the Bioreactor.
The Cleaning Valve is normally closed and opens during the cleaning cycle to direct cleaning
solution circulated by the flush pump into the top of the membranes.
The Vent Valve is spring closed and normally stays that way. During a backwash cycle it is
opened briefly to purge air out of the permeate side of the membranes to ensure the permeate
side of the membranes stay full.
The Diffuser Flush valve is normally closed and opens during the backwash portion of the
flush dump cycle. This allows permeate water to be forced into the diffusers to flush out any
solids that may be forming.
The Backwash Valve is normally closed. During a backwash the valve opens briefly to allow
the backwash pump to pump permeate back through the membrane.
The Permeate Valve is held open during normal operation. During each backwash cycle it
closes briefly to prevent the backwash pump from pushing permeate back through the permeate
PUMP.
The Membrane Air Valve is normally closed and held open during normal operation to
provide air to the membrane air diffusers. Do NOT leave this valve open with empty
membranes! The air will quickly dry out the membranes doing permanent damage to them.

Appendix D. Alarm List and Troubleshooting
The following is a list of the alarm codes the system can generate, what they mean, and
possible corrective action.
I Rotary Brush Screen Tank High Level
This alarm can be activated by both the level transmitter and the redundant high level float
switch in the screenings tank for both the A and B Dynalifts. This alarm indicates that the tank is
being filled by the feed pumps faster than the screenings pumps are removing the wastewater.
Possible causes for this alarm are:
• Failure of the drum screen tank level transmitter.
• Failure of one or more of the screenings pumps. Check alarm history for pump related
failure messages.
2 Bioreactor A High Level
This alarm is activated by the level transmitter in the bioreactor. This alarm is unlikely to
happen in normal operation. This alarm affects both the A and B Dynalifts as they share a split
feed flow. It shuts off the screenings pumps, except if the pumps are running in hand from the
HOA switch on the MCC. It could happen if:
• One or more of the system feed pumps in EQ tank 1 are left running in Hand from the
HOA switch on the MCC.
• The set point for pump shutoff is set too high.
3 Bioreactor B High Level
Same as bioreactor A high level above.
4 Anoxic Tank A High Level
This alarm is activated by a non adjustable float switch in the anoxic tank. It is very unlikely
to occur in normal operation. This alarm affects both the A and B Dynalifts as they share a split
flow from EQ tank 1. It shuts off both the system feed pumps in EQ tank 1 and the screenings
pumps, except if the pumps are running in hand from the HOA switch on the MCC. It might
occur i£
• The level set points for the bioreactor were to be set to a very high level.
• The level transmitter in the bioreactor failed and was showing a low level when in
fact the level was high. This would keep the system feed pumps running.

www.dynatecsystems.com

Operations and Maintenance Manual Ultrafilter Wastewater Treatment System -86-
5 Anoxic Tank B High Level
Same as tanks A above.
6 Backwash Tank High Level
This alarm is activated by both the level transmitter in the backwash tank and a redundant
float switch. It is highly unlikely in normal operation since the tank overflows to discharge
permeate. This alarm would indicate a blockage in the discharge pipe, or a closed valve.
7 Backwash Tank Low Level
This alarm is activated by the level transmitter in the backwash tank. This alarm shuts off the
backwash pump to prevent seal damage. The pump will be used again when the level rises to the
Backwash Tank Reuse Level Low set point (figure 36). However this would indicate that the
membranes are not being properly backwashed, which could lead to serious plugging in a short
time. It can be caused by:
• A backwash rate greater than the permeate production rate from the membranes.
• A permeate reuse rate greater than the permeate production rate from the
membranes.
8 EQ Tank Low Level
This alarm is activated by the level transmitter in EQ tank. It would most likely be caused by
leaving the system feed pump(s) in Hand position.
9 Aeration Blowes Cooling Fan Overload
This alarm is activated by any overload contacts on each of the cooling fan starters in the
MCC. It indicates a problem with one of the cooling fans, and the fan will be shutdown. In a
short time the affected blower will overheat. Holding your hand over the cooling air outlet of
running blower will identify the one that has failed. You should switch to the backup blower
immediately. Opening the noise cover on the blower also may allow you to keep the blower
running without overheating. If nothing is done the blower overheat switch will eventually shut
the blower down, which could cause serious membrane plugging and loss of the biomass in the
bioreactor.

Operations and Maintenance Manual Ultrafilter Wastewater Treatment System -87-
10 Aeration Blower Cooling Fan Failure
This alarm is activated by the auxiliary contact on the motor starter in the MCC.. It can be
caused by:
• The HOA switch being left in the Off position.
• The overload relay tripped in the MCC.
• A blown fuse on the control transformer in the MCC bucket.
• A burned out contactor coil
• A broken wire
• A bad output relay on the PLC IFM card
• A blown fuse in the IFM card,
• A bad output in the PLC output module itself.
See the previous alarm for immediate actions to take.
11 Process Blower Overheat
This alarm is activated by the overheat switch which is part of the temperature gauge mounted
on top of the blower. It can be caused by failure of the blower cooling fan as described above, or
by a restriction in the airflow through the blower, as would happen if the filter was very dirty.
This alarm is the last defense against the blower being destroyed so it will shut the blower
down. This will lead to many other alarms due to a lack of process air.
12 Process Air Bioreactors High Temperature
This alarm is activated by the temperature transmitter located on the process blower air header
between blowers 1 and 2. This alarm is a warning, it does not stop the blower. However if the
temperature continues to rise the blower will stop when the temperature reaches the Blower
Temperature High Stop set point. Blowers compress the air raising its temperature. Possible
causes for this alarm are:
• High ambient air temperature.
• Significant obstruction in the air intake duct work to the blower.

Operations and Maintenance Manual Ultrafilter Wastewater Treatment System -88-
13 Process Air Membranes High Temperature
Same a process air temperature A above.
14 Circulation Pump Failure to Run
This alarm is activated by the auxiliary contact on the motor starter contactor in the MCC.
This alarm puts the A Dynalift into Stop, to prevent the membranes from plugging. It can be
caused by:
• The HOA switch being left in the Off position.
• The overload relay tripped in the MCC.
• A blown fuse on the control transformer in the MCC bucket.
• A burned out contactor coil.
• A broken wire.
• A bad output relay on the PLC IFM card.
• A blown fuse in the IFM card.
• A bad output in the PLC output module itself.
This alarm functions the same as the previous alarm for circulation pump 1, except that it
stops the A or B Dynalift based on which Dynalift the pump has been selected for.
15 Circulation Pump Overload
This alarm is activated by any of the overloads on the circulation pumps tripping. It is
informational only. The affected pump will be stopped by the Circulation Pump Failure alarm.
This alarm lets you know why.
16 Circulation Pump Low Suction Pressure
This alarm is activated by the suction pressure switch located between the circulation pumps
and the strainer. It works for pumps I and 2. The causes for this alarm are:
• Suction strainer is clogged.
• One of the three valves in the suction line are closed.

Operations and Maintenance Manual Ultrafilter Wastewater Treatment System -89-
17 Drum Screen Failure to Run
This alarm is activated by the current sensor located in the Safety Relay panel on the wall in
the screenings room. This alarm shuts down the system feed pumps to keep them from
continuing to send wastewater to the drum screen and overflowing on to the floor. The system
will soon run out of wastewater and a low level in the bioreactors will shut both the A and B
Dynalifts off. It indicates the drum screen is not running because:
• The E-stop on the Safety Panel has been pressed.
• The Safety Panel Start button has NOT been pressed.
• One of the safety switches on the drum screen doors is not detecting the magnet.
• The HOA switch on the MCC is in the Off position.
• The overload relay tripped in the MCC.
• A blown fuse on the control transformer in the MCC bucket.
• A burned out contactor coil in the MCC
• A burned out contactor coil in the safety control cabinet
• A broken wire
• A bad output relay on the PLC IFM card
• A blown fuse in the IFM card,
• A bad output in the PLC output module itself.
• The UPS in the PLC cabinet is off.
• A fuse in the UPS output is blown.
18 Dynalift Feed Valve Failure
This alarm is activated by the limit switches in the Open/Close beacon on top of the feed
valve. It indicates that the rotation of the valve has failed to reach one of the limit switches,
either open or closed. The system does not stop running. The valve should be examined
immediately for problems.

19 Test
This alarm is activated by the Alarm Test touch button on the Maintenance screen. Its
purpose is to test that the alarms work properly and that the horn and light can sound. The
switch is a toggle, you must press it a second time to clear the alarm.
20 Dynalift Air Flow High
This alarm is activated by the pitot tube differential pressure sensor located in the galvanized
pipe that feeds air to the A Dynalift membranes. It is informational only. It just tells you that for
some reason you are using more air than previously. This may indicate a valve has been adjusted
differently.
21 Dynalift Drain Valve Failure
This alarm is activated by the limit switch on top of the valve actuator. It indicates that the
drain valve has not properly closed. This could result in the loss of all the biomass in the
bioreactor back into EQ tank 1. For this reason this alarm shuts down the A Dynalift and closes
the Bioreactor Isolation valve.
22 Dynalift Air Flow Low
This alarm is activated by the pitot tube differential pressure sensor located in the galvanized
pipe that feeds air to the A Dynalift membranes. It indicates that the membranes are not getting
enough air and plugging may be occurring. The rotameters near the blowers indicate the actual
air flow in CFM. This condition may be caused by:
• Low process blower pressure.
• A closed valve.
• Plugging of the membrane air diffusers.
23 Dynalift SHUTDOWN! High Trans Membrane Pressure
This alarm is sensed by the PLC calculating the difference between the membrane feed
pressure and the membrane permeate pressure. This pressure difference is what drives the
permeate through the membrane. A high TMP indicates fouling of the membrane, and can lead
quickly to plugging. The usual course of action is to chemically clean the membranes using the
automated cleaning process.
This alarm puts the A Dynalift into stop.

24 Backwash Pumps Overload
This alarm is activated by the overload relay located in the MCC. It indicates that the
backwash pump has overloaded. Since the backwash pump actually pumps only very clean
permeate and runs for just 5 seconds it is unlikely to get this alarm in normal operation. It could
be caused by:
• Something broken inside the pump, like a seized bearing.
• One fuse blown in the MCC which single phases the motor.
25 Backwash Pump Failure to Run
This alarm is activated by the auxiliary contact on the motor starter in the MCC. It indicates
the backwash pump has failed to run. This could be caused by:
• The HOA switch on the MCC is in the Off position.
• The overload relay tripped in the MCC.
• A blown fuse on the control transformer in the MCC bucket.
• A burned out contactor coil in the MCC.
• A broken wire.
• A bad output relay on the PLC IFM card.
• A blown fuse in the IFM card.
• A bad output in the PLC output module itself.
26 Dynalift SHUTDOWN! Low Permeate Flow
This alarm is activated by the flow meter on the backwash skid. It may be caused by:
• The HOA switch for the permeate pump on the MCC is in the Off position.
• The permeate pump is in disabled mode.
• A clogged or defective flow meter.
• A blown fuse on the control transformer in the MCC bucket.
• A broken wire.

• A blown fuse in the IFM card.
• A bad output in the PLC digital output module or analog output module
27 System feed Pumps Overload
This alarm is activated by any of the overloads tripping for the system feed pumps in EQ tank
1 and 2. You will also get a failure to run alarm for the specific pump, so this alarm helps you
troubleshoot that problem. This alarm may be caused by:
• Clogging of the system feed pump.
• A bearing failure in the pump.
28 System feed Pump Seal Failure
This alarm is activated by a sensor inside the system feed pump. It works by sensing the
resistance across two probes. Water reaching the probes shorts them out and the sensing relays
in the MCC then trigger the alarm. The pump with the failed seal should be disabled and
removed from the EQ tank immediately before more serious damage can occur.
29 System feed Pump Failure to Run
This alarm is activated by the auxiliary contact on the motor starter in the MCC. It can be
caused by:
• The HOA switch on the MCC is in the Off position.
• The overload relay tripped in the MCC.
• A blown fuse on the control transformer in the MCC bucket.
• A burned out contactor coil in the MCC.
• A broken wire.
• A bad output relay on the PLC IFM card.
• A blown fuse in the IFM card.
• A bad output in the PLC output module itself.
30 Screen Transfer Pumps Overload
This alarm is activated by any of the overloads tripping for the pumps in the screening tank.
You will also get a failure to run alarm for the specific pump, so this alarm helps you
troubleshoot that problem. This alarm may be caused by:

• A bearing failure in the pump.
• A broken wire feeding the pump.
• Overload relay set too low for motor rating.
31 Screen Transfer Pump Failure to Run
This alarm is activated by the auxiliary contact on the motor starter in the MCC. It can be
caused by:
• The HOA switch on the MCC is in the Off position.
• The overload relay tripped in the MCC.
• A blown fuse on the control transformer in the MCC bucket.
• A burned out contactor coil in the MCC.
• A broken wire.
• A bad output relay on the PLC IFM card.
• A blown fuse in the IFM card.
• A bad output in the PLC output module itself
32 Dynalift SHUTDOWN! Bioreactor Low Level
This alarm is activated by the submersible level transmitter in the Bioreactor A tank. The set
point should be set below the lowest system feed pump turn on point. This alarm also puts
Dynalift A into Stop mode to prevent losing all the biomass, or concentrating up the MLSS to a
level that plugs the membrane. This alarm may be caused by:
• Pumping off sludge without shutting the A Dynalift down.
• Failure of one or more of the system feed pumps.
• Failure of the rotary screen.
• Failure to restart the rotary screen after servicing.
• Failure of one or more of the screening pumps.
• A valve left close in the piping from the screening pumps to the anoxic tank.
• Failure of the level transmitter in the bioreactor.

33 Dynalift High Permeate Flow
This alarm is activated by the flow meter on the backwash skid. It is highly unlikely to get
this alarm in normal operation. It is provided simply so you can bracket your normal flows with
alarm points in the event something unusual were to occur. It can be caused by:
• Alarm set point too low for normal operational fluctuation.
• Permeate pump in Hand with flow rate set high.
• Permeate flow setting set points too high.
An unused alarm point in the Dialer Critical indicator pages.
34 Bioreactor A High Air Flow
This alarm is activated by the pitot tube differential pressure transmitter located in the
galvanized pipe feeding process air to the bioreactor. This alarm could be caused by:
• Low level in the bioreactor.
• Broken or missing diffusers in the bioreactor.
35 Dynalift Low Trans Membrane Pressure
This alarm is sensed by the PLC calculating the difference between the membrane feed
pressure and the membrane permeate pressure. This pressure difference is what drives the
permeate through the membrane. A low TMP alarm can be caused by:
• Alarm set point too high for low flow TMP conditions.
• Failure of the Membrane Feed Pressure transmitter.
• Failure of the Permeate Pressure transmitter.
• Failure of the Permeate Pump
• Failure of the Circulation Pump.
36 Bioreactor Low Air Flow
This alarm is activated by the pitot tube differential pressure transmitter located in the
galvanized pipe feeding process air to the bioreactor. This alarm could be caused by:
• Closed or poorly adjusted valves in the galvanized piping to the bioreactor.
• An increase in the level of the bioreactor which raises the pressure needed to push
air into the bioreactor.

Operations and Maintenance Manual Ultrafilter Wastewater Treatment System -95-
• Clogged diffusers in the bioreactor.
• Low air pressure in the process air header
• Failure of the process air blower.
• Alarm set point too high for normal flow change due to automatic valve operation.
37 Anoxic Tank High ORP
This alarm is activated by the ORP sensor in the side of the Anoxic Tank. This alarm may be
caused by:
• High DO in Bioreactor.
• Excessive air to the membranes.
• Lack of carbon to feed bacteria.
38 Bioreactor Low Level
This alarm is a warning activated by the submersible level transmitter in the Bioreactor A
tank. The set point should be set below the lowest system feed pump turn on point. This alarm
may be caused by:
• Pumping off sludge without shutting the A Dynalift down.
• Failure of one or more of the system feed pumps.
• Failure of the rotary screen.
• Failure to restart the rotary screen after servicing.
• Failure of one or more of the screening pumps.
• A valve left close in the piping from the screening pumps to the anoxic tank.
• Failure of the level transmitter in the bioreactor.
39 Anoxic Tank Low ORP

40 Bioreactor Low Dissolved Oxygen
This alarm is activated by the Dissolved Oxygen (DO) transmitter in the Bioreactor A tank.
Under normal operation the DO level wanders up and down between the DO high set point and
the DO low set points. This alarm may be caused by:
• A system disturbance such as starting the system up, or shutting it down for maintenance.
• Bioreactor air pulse valves in Hand (closed)
• Pulse valve limits set wrong.
• Failure of the open pulse valve.
• Failure of the bioreactor air blower.
• Out of calibration DO transmitter. The DO transmitter has an electrolyte filler that must
be replaced periodically.
41 Bioreactor High pH
This alarm is activated by the pH transmitter installed on the side of the bioreactor A near the
platform. Under normal operation the pH of the incoming waste water is slightly above 7.0. A
caustic injection system has been provided to compensate for possible low pH but is most likely
not needed. If the injection system is running then the like causes of this alarm would be:
• pH set point too high.
• Caustic pump stroke set too high.
• Caustic pump PID loop not tuned properly.
42 Dynalift Circulation Pump Low Suction Pressure
This alarm is activated by the pressure transmitter in the circulation pump suction header. It
can be caused by:
• Strainer clogged.
• Strainer valve closed.
• Set point too high.
• Bioreactor isolation valve closed

43 Bioreactor High Dissolved Oxygen
This alarm is activated by the Dissolved Oxygen (DO) transmitter in the Bioreactor A tank.
Under normal operation the DO level wanders up and down between the DO high set point and
the DO low set points. This alarm may be caused by:
• A system disturbance such as starting the system up, or shutting it down for maintenance.
• Air pulse valves in Off (open).
• Air pulse valve limits too high or too wide.
• Out of calibration DO transmitter. The DO transmitter has an electrolyte filler that must
be replaced periodically.
44 Dynalift SHUTDOWN! High Feed Pressure
This alarm is activated by the pressure transmitter located at the center of the feed header on
the membrane rack. In normal operation the pressure here is reduced to a little less than the
static head required (about 5.06 psi) to overflow water into the top header, because the air
injected at the bottom of the membrane makes the water less dense. This alarm could be caused
by:
• Loss of air flow to the membrane rack.
• Plugging of the membrane which increases the resistance of water flow through the
membranes.
• Failure of feed pressure transmitter.
45 Dynalift Low Feed Pressure
This alarm is activated by the pressure transmitter located at the center of the feed header on
the membrane rack. In normal operation the pressure here is reduced to a little less than the
static head required (about 5.06 psi) to overflow water into the top header, because the air
injected at the bottom of the membrane makes the water less dense. This alarm could be caused
by:
• Clogged suction strainer on circulation pump inlet.
• Closed Bioreactor Isolation valve.
• Circulation pump failure, or worn impellor.
• Feed valve failure.

0 Drain valve failure in the open position.
• Very low level in the Bioreactor.
46 Dynalift High Permeate Pressure
This alarm is activated by the pressure transmitter located at the center of the permeate header
on the membrane rack. This alarm is likely only during the backwash cycle which occurs
frequently. During the backwash cycle the permeate valve on top of the backwash skid closes,
the backwash valve opens, and the backwash pump starts, forcing permeate backwards through
the membrane. The butterfly valve above the backwash pump is throttled to keep the backwash
pressure not more that 14.7 psi to avoid damaging the membrane. This alarm can be caused by:
• The backwash pump throttling valve is too far open.
• The membrane is very badly fouled (TMP would be very high)
• Membrane is badly plugged.
47 Dynalift Low Permeate Pressure
This alarm is activated by the pressure transmitter located at the center of the permeate header
on the membrane rack. The permeate pump on the backwash skid pulls permeate out of the
membrane skid, except during backwash. This alarm could be caused by:
• Excessive permeate flow rates.
• Badly fouled membranes.
48 Permeate Pump High Pressure
This alarm is activated by the pressure transmitter located in the discharge pipe above the
permeate pumps on the backwash skid. The permeate pump pumps permeate into the backwash
tank through a diaphragm valve at the top of the backwash skid that provides some back pressure
so that the permeate won't just gravity flow through the pump into the backwash tank at a rate
greater than desired. This alarm can be caused by:
• Very high permeate rate.
• Permeate flow control diaphragm valve closed too far.
• Permeate pump HOA switch in Hand and speed set high.

49 Permeate Pump Low Pressure
This alarm is activated by the pressure transmitter located in the discharge pipe above the
permeate pumps on the backwash skid. The permeate pump pumps permeate into the backwash
tank through a diaphragm valve at the top of the backwash skid that provides some back pressure
so that permeate won't just gravity flow through the pump into the backwash tank at a rate
greater than desired. This alarm can be caused by:
• Very low permeate rate.
• Permeate flow control diaphragm valve opened too far.
• Failure of the permeate pump
50 Process Air Bioreactor High Pressure
This alarm is activated by the pressure transmitter located on the Bioreactor process air header
behind the blowers. This transmitter controls the speed of the blower selected for the bioreactors
to maintain a constant pressure. A high pressure alarm could be caused by:
• The alarm set point is too low.
• The blower set point has been raised.
• The PID loop is poorly tuned.
• Valves closed on the lines going to the bioreactors.
• Blower HOA switch in hand and speed set too high.
• Failure of the blower relief valve.
51 Process Air Membrane High Pressure
This alarm works the same as Process Air Bioreactor High Pressure above (alarm 114).
52 Process Air Bioreactor Low Pressure
This alarm is activated by the pressure transmitter located on the process air header behind the
blowers. This transmitter controls the speed of the blower to maintain a constant pressure. A
low pressure alarm could be caused by:
• Blower pressure set point too low.
• Alarm set point too high.

0 Failure of blower relief valve.
• Failure of blower to run.
• Valves opened to bioreactor and membrane so far that the blower cannot keep up.
53 Process Air Bioreactor Low Pressure
This alarm works the same as Process Air Bioreactor Low Pressure above (alarm 119)
54 Effluent Pump Failure to Run
This alarm is activated by the run contact on the motor starter in the MCC bucket for this
pump. the alarm could be caused by:
• MCC bucket switch turned off.
• MCC HOA switch in off position.
• Over load relay tripped.
• A failure of the battery charging circuit to recharge the battery.
SS E-STOP Pressed
This alarm is activated by pressing the E-stop. It is included merely to log in the alarm
history that someone pushed the E-stop. This may help explain an unintended shut down for
which no other cause can be found.

BODY:
Wafer style cast two-part bolted body, both internally machined, with reinforcing ribs in larger
diameters for extra body strength.
The stainless steel version valves include internal high density polyethylene sliders (HMWPE)
that ensure smoother gate traveling.
Full port design to allow a greater flow capacity and to guarantee a minimal pressure drop.
SELFCLEANING GATE:
Stainless steel as standard. One piece through -going gate with o-port design. When closing, the
gate cuts and moves a disc of material downwards, which is again returned to the flow when
opening. Gate is polished on both sides to avoid jamming and to ensure a greater seal between
the gate with both packing and seat.
The thickness and/or the material of the gate can be changed on request for higher pressure
requirement
SEAT: (resilient)
Unique design that mechanically locks the seal in the interior of the valve body with a
stainless steel retainer ring. Standard EPDM also available in different materials such as
Viton, PTFE, etc.
PACKING:
Double stuffing box with several layers of braided fibre plus an EPDM o-ring, with an easy
access and adjusting packing gland ensuring a tight seal. Long -life braided packing is
available in a wide range of materials.
STEM:
The standard stainless steel stem offers a long corrosion resistant life. For rising stem
handwheel actuators only, a stem protector is provided for additional protection against dust
while the valve is in the open position.
ACTUATORS:
All actuators supplied by ORBINOX are interchangeable, and supplied with a standard
mounting kit for installation purposes on site.
YOKE or ACTUATOR SUPPORT:
Made of EPDXY coated steel (stainless steel available on request). Compact design makes it
extremely robust even under the most severe conditions.
EPDXY COATING:
The epoxy coating on all ORBINOX cast iron and carbon steel valve bodies and components
is electrostatically applied making the valves to be corrosion resistant with a high quality
finished surface. The ORBINOX standard colour is RAL-5015 blue.
GATE SAFETY PROTECTION:
ORBINOX automated valves are provided with gate guards in accordance with EU Safety
Standards. The design feature prevents any objects from being caught accidentally while the
gate is moving.

Valve components can be protected or coated for a longer life expectancy,
depending on the application of the valves and the valve service conditions.
At ORBINOX we can offer alternative treatments and coatings for the different
valve components to improve their properties against abrasion (Stellite,
polyurethane...), against corrosion (Halar, Rilsan, galvanizing...) and against
adherence (polishing, PTFE... ).

Cottages of Boone Wastewater Treatment Facility
Residuals Management Plan
This document serves as The Cottages of Boone Wastewater Treatment Facility Residual
Management Plan, and will remain on site at the wastewater treatment facility for review by
The State of North Carolina DEQ personnel.
The Cottages of Boone wastewater facility pumps sludge from the activated sludge treatment
process to its onsite 36,166 gallon aerobic digestion storage tank for further treatment to
meet the 503 Regulations. The treatment process currently sends about 1000 gallons of
sludge daily to the digester holding tank and is aerated for proper treatment. The air is
periodically turned off and the sludge is allowed to settle, and the supernate is decanted
from the tank to allow more room in the digester. This process is continued until the tank
reaches the 70% full mark and can no longer be decanted. Once the digester holding tank
reaches the 70% full mark, the operator will schedule to have the tank emptied by contracted
pump companies.
The following companies are approved to haul digested sludge from the Cottages of Boone
digester to the City of Boone wastewater treatment facility for final disposal.
- Al Appalachian Pumping - [phone]
124 Cheyenne Ln
Boone, NC 28607
- Triple T Pumping - [phone]
1372 NC-194
Boone, NC 28607
- Doby's Septic — [phone]
712 S. Jefferson Ave
West Jefferson, NC 28694
All records of pumping activities including, date, time, gallons removed, location of final
disposal, and company performing the hauling activities will be kept on site at the
wastewater treatment facility for no less than 5 years.

PROCEDURES FOR CLEANUP AND REPORTING OF SEWAGE SPILLS
PURPOSE:
To protect the citizens of North Carolina, and the environment by ensuring a timely and
thorough response to Sanitary Sewer Overflows (SSOs) and Bypasses from the treatment
facility.
SCOPE:
This procedure applies to The Cottages of Boone employees or contractors that, in the course
of their work may deal with SSOs and bypasses. At a minimum, these procedures will be
reviewed on an annual basis or whenever revised guidance from state or federal authorities
dictate a revision is necessary.

RESPONSE TIME REQUIREMENTS:
Utility Outage or Spill Response Time: Upon notification of a spill or utility outage in the
collections system or treatment plant, Envirolink, Inc. shall respond and take action to
safeguard life and the property during business hours and non -business hours.
NOTIFICATIONS:
Per Condition IV.13 of the Permit, any spill that reaches surface waters must be
reported by telephone to the Winston-Salem Regional Office at [phone] as soon
as possible, but in no case more than 24 hours.
The following procedures also all for sewage spill of 1,000 gallons or more to surface
waters of the State, per N.C.G.S. 143.215.1C. (Note: Conveyances such as drainage
ditches and storm sewers are considered waters of the State).
• For discharges of 1,000 gallons or more of untreated wastewater to surface
waters, issue a press release within 48 hours of first knowledge to the
Newspaper.
• For discharges of 15,000 gallons or more of untreated wastewater to surface
waters, shall publish a public notice captioned "NOTICE OF DISCHARGE OF
UNTREATED SEWAGE" within 10 days after NCDEQ has determined the
counties that are significantly affected by the discharge and approved the form

and content of the notice and the newspapers in which the notice is to be
published. See N.C.G.S. 143.215.1C for additional information.
REPORTING SSOs:
Before any SSO or bypass is reported to the State, the ORC or the Backup ORC must visit and
evaluate the spill site within 24 hours. Once the spill site has been evaluated by the ORC or the
Backup ORC, the responsible person should discuss the spill, determine estimated volumes and
causes before calling the Division within the 24 hour time frame.
Containment
Upon learning of such an occurrence, the first priority shall be to assess the situation and
mobilize resources necessary to remove the blockage or untreated discharge, contain the
SSO, and stabilize the overflow condition to the max extreme. Notification should be made
to the ORC at this time. As soon as the extent of the SSO or bypass has been determined, a
containment berm or a dam should be established at the lower edge of the SSO or bypass, or
at an area that meets the needs of containment and clean up operations. The containment
dam should be large enough to prevent breaching in dry weather conditions.
Force Main or Inaccessible Gravity Sewer Spill
In the event a spill occurs at a pump station with no bypass capability or at a force main or
gravity sewer where no access to a dump point exists, pump and haul or bypass operations
will be considered. Where pump and haul operations are deemed the best solution, sewer
will be collected from the closest tanker access point for continuous loading operations while
causing minimum environmental damage. Consideration should be made for traffic control,
noise, access, etc.

**See attached Pump and Haul Record Form -Complete for each load
For Spills involving Asphalt or Concrete
1. Set up containment at or near any threatened storm drainage system; Every attempt
should be made to prevent the spill from entering the drainage structures.
2. Spread dry sand or absorbent material to a depth of 1 inch. Let stand for one hour and
sweep up. If moisture or grease is still present, repeat.
3. After removing the contaminated material, wash down the area with high water pressure
and a mild bleach solution and then pump residue back into the sewer system.

4. If the spill enters a storm drainage structure, a Reportable Spill has occurred and
therefore a Spill Report should be filed with NC DWQ and treated as a SSO affecting
Waters of the State. Reported volumes would include the initial estimated spill; plus any
flush water used; minus the calculated amount removed from storm drain system.
SSO or Bypass affecting Waters of the State
1. Take conductivity and dissolved oxygen readings of the receiving stream to determine the
proper placement of a dam within the intervals on the Conductivity Readings Form.
While taking the conductivity readings, be sure to notate them on the Spill &
Conductivity Reporting Form. The dam needs to be constructed near a manhole or at a
location which is accessible to the jet/vacuum truck. Placement of the dam should be at a
point where the lowest conductivity reading is measured.
2. Build the dam using dirt that is capable of handling creek and hydrant flow without
breaching during dry weather conditions. Position two pumps at the dam capable of
handling creek and hydrant flow with one pump in use and the second as backup. Have a
backhoe at the site with additional material at all times so that the earthen dam can be
rebuilt if a breach does occur. Pump SSO release from the dam into the manhole.
3. Put up warning tape, "Danger Do Not Enter" from the SSO site to the pump site on both
sides of the creek in populated areas. In unpopulated areas restrict access where there is
any chance of human contact with the SSO.
4. Flush the stream with de -chlorinated water from a sufficient number of hydrants to
remove the waste product from the creek. Continue to pump and flush the stream until
the conductivity measurements or readings are equivalent to upstream receiving stream or
hydrant water conductivity readings, whichever is higher. Make sure that all readings
taken during cleanup are recorded on the Spill & Conductivity Reporting Form and
taken within the intervals on the form.
5. If there is rip -rap in the creek, wash down with high water pressure until there is no
noticeable waste residue remaining on or within the rip -rap structure.
6. If the creek flows into a body of water used for recreation and/or drinking water supply,
notify the affected officials as soon as possible.
7. Continue periodic monitoring of conductivity and Dissolved Oxygen readings. All
additional readings should be notated on the Spill and Conductivity Reporting Form.
Take an upstream and downstream fecal coliform every 24 hours as needed until the
waterway is restored to pre -event condition.
SSO not reaching Waters of the State
1. In open areas spread powdered lime heavily over the spill site, till into the ground and
then repeat the procedure again but not within 24 hours of predicted rain fall event. Seed
the disturbed area and place straw over the tilled area. Soil may need to be removed and
replaced with clean fill material for a large spill where the ground has become saturated.
SSO REPORTING PROCEDURES
1. Upon discovery of a possible SSO or bypass, notify the ORC or Back up ORC

Eric Youngs (ORC) Cell# 910-465-1219
David McDaniel (Area Manager) Cell# 336-880-1115
Madelyn Mills (Public Notification Coordinator) Office# 984-365-9160
2. The individuals listed above will be the Point of Contact between The Cottages of Boone
and NC DEQ or the Division of Emergency Management on SSO or bypass matters.
These individuals will report overflows from any sewer line or pump station, or the
bypass of any wastewater treatment system or any component thereof. If Media
communications become apparent, the Executive Director will be the POC for all Media
questions.
3. Reportable spills must be called into NC DWQ (336-776-9800) within 24 hours of first
knowledge of discharge. Document on the Spill Report Form the date, time, incident
number and person contacted.
4. During weekends and holidays when DWQ cannot be reached, The Division of
Emergency Management will be called at 1-800-858-0368 providing the information
requested. Document on the Spill Report Form the date, time, and person contacted.
Upon arriving to work after the weekend or a holiday, DWQ should be contacted to
receive the incident number for the reported spill.
5. The ORC/Backup ORC should be notified immediately so they have an opportunity to
visually see the spill. This will allow the ORC/Backup ORC to provide better estimated
volumes. The ORC or the Backup ORC is also required by the Collection System
Permit to visit the spill site.
6. The ORC/Backup ORC must fill out the State approved Sanitary Sewer Overflow Form.
A legible copy will be faxed within five (5) days to NCDENR, Winston Salem Regional
office (336-776-9800). If the Director of Operations is unavailable, the ORC will ensure
that the necessary paperwork is completed. Records of spills, including those that are
not required to be reported will be maintained for at least three (3) years and will be made
available to NCDENR staff upon request.
