The West Lincoln High School's wastewater treatment plant(WWTP) located on 176 Shoal Road
in Lincolnton, North Carolina currently operates under a discharge permit (NC0041246). The
WWTP has an existing wastewater treatment system that utilizes a Hayward bag filter system(two
filters)to remove additional FOG and TSS prior to the effluent entering the recirculating sand filter
system. Since the school year began, the operator has had to manually empty the bag filters as
often as every two days. MacConnell & Associates has been contracted to design an immediate
solution for the WWTP. This memorandum consists of an evaluation of the existing conditions
and the proposed changes will resolve the frequent bag filter maintenance.
Existing Conditions
The existing 0.014 MGD wastewater treatment facility consists of the following components:
• 2- 14,000-gallon septic tanks operated in series
• 12,000-gallon dosing tank with alternating duplex grinder pumps
• 12,000-gallon equalization tank
• Hayward bag filter system (two filters)
• 2-Recirculating sand filters w/drip emitter flow distribution system
• Flow splitter box
• Ultraviolet disinfection
• Effluent trapezoidal flume w/ultrasonic flow meter
• Effluent duplex pump station/force main
Since the school year began, the operator has had to manually empty the bag filters as often as
every two days. The grease traps that serve the middle school and high school have been pumped,
but the issue still prevails. Results from a sample grab in the dosing tank revealed that FOG
concentrations were within the treatment capacity for the system,but the TSS concentrations were
high. High concentrations of TSS can be attributed to peak flow times when suspended solids are
forced to pass through the septic tank effluent filters and as a result, solids have accumulated in
the dosing tank over time. This condition is exacerbated by the current use of grinder pumps,
which use blades to macerate solids as it pumps effluent. As a result, the settled solids in the
dosing tank are resuspended into a slurry like consistency before reaching the filters.
Proposed Conditions
A long-term solution and plan for the WWTP is add flow equalization, which will take time for
the Lincoln County Schools to budget and allocate funds. As such, M&A has been requested to
West Lincoln High School WWTP
Minor Modification
MacConnell&Associates,P.C. Project No.: C21401.00 1

submit a minor modification that will serve as a temporary solution. We propose replacing the
grinder pumps,which are a poor application for dosing a recirculating sand filter with drip emitters,
with Sta-Rite STEP pumps. Both pumps shall be housed in pump screens with 1/8-in perforations
to prevent larger solids from reaching the filters. We also propose replacing the first-in-series
Hayward bag filter and replacing it with two 2"LP Disc-Kleen Filters fitted with mesh 80 screens.
The spin disc filters will provide equivalent tertiary filtration as the existing Hayward bag filters
(200 micron) for the effluent entering the recirculating sand filters while alleviating manual
cleaning every two days. The Disc-Kleen filters provide an automated backwash system which
will tie into the existing flush line in the control building as shown in drawings (empties to second
septic-in-series). For the pumps, some plumbing will need to be done. The new pumps shall be
wired to the existing control panel. For the filters, some plumbing will need to be done, but no
electrical because the backwashing system may either be plugged into an outlet or battery powered.
Please note that with the installation of the two spin disc filters, the second bag filter is no longer
an essential component to the WWTP will be but left as a redundancy at the client's request.
Conclusion
In conclusion, the proposed changes will consist of replacing the grinder pumps with Sta-Rite
STEP pumps, installing pump screens, and replacing the first-in-series Hayward bag filter with
two 2" LP Disc-Kleen Filters. Flow rates are not proposed to increase. This installation will
require some pipework and minor electrical work. All proposed units shall provide adequate levels
of treatment for the WWTP's permitted standards.

1. The Pennittee shall submit discharge monitoring reports electronically using the Division's eDMR system. [See A.
(2•)].
2. In the event that the wastewater treatment plant's ultraviolet(UV)disinfection system should fail,underperform,or
otherwise be removed from effective service,the permittee or his agent should immediately inform the Water Quality
Regional Operations Section staff of the Mooresville Regional Office of this development and discuss temporary,
alternate means for disinfection of the effluent.
If chlorine compounds are used as temporary means of disinfection,the total residual chlorine(TRC)concentration of
the effluent must be monitored while this method of disinfection is in use and values must be reported on the discharge
monitoring report. TRC in the effluent may not exceed 28 µg/L;therefore,dechlorination methods may also be
necessary to ensure protection of water quality in the receiving stream.
Use of a disinfection system other than the permitted UV system during circumstances not deemed as emergency
and/or temporary(replacement of lamps,lamp cleaning or maintenance,etc.)will be considered a violation of the
terms of this permit.
The Division shall consider all effluent TRC values reported below 50 µg/l to be in compliance with the permit.
However,the Permittee shall continue to record and submit all values reported by a North Carolina certified laboratory
(including field certified),even if these values fall below 50 µg/l.
THERE SHALL BE NO DISCHARGE OF FLOATING SOLIDS OR VISIBLE FOAMIN OTHER THAN TRACE AMOUNTS.

• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports

3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to
the Division. Requests for temporary electronic reporting waivers must be submitted in writing to
the Division for written approval at least sixty (60) days prior to the date the facility would be
required under this permit to begin submitting monitoring data and reports. The duration of a
temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring
data and reports shall be submitted electronically to the Division unless the permittee re-applies for
and is granted a new temporary electronic reporting waiver by the Division. Approved electronic
reporting waivers are not transferrable. Only permittees with an approved reporting waiver request
may submit monitoring data and reports on paper to the Division for the period that the approved
reporting waiver request is effective.

the Permittee's(or any satellite POTW's,if different from the Permittee)NPDES,collection system,or non-discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works(POTW)
A treatment works as defined by Section 212 of the CWA,which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage,treatment,recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402,only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization,or municipality,as defined in section 502(4)of the CWA,which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context,the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a"satellite POTW organization." [15A NCAC 02H.0903(b)(26)]
"Significant Industrial User" or"Stull
An Industrial User that discharges wastewater into a publicly owned treatment works and that[15A NCAC 02H

HOW AUTOMATIC DISC FILTER TECHNOLOGY WORKS
D A filter element(spine)contains a stack of compressed discs with an
overlapping series of grooves that force the debris to move through
the numerous trap points.
B FILTRATION PROCESS
Unfiltered water passes through a stack of tightly compressed discs.
_ � The water is forced to flow through the interlocking grooves of the
C disc rings where debris is trapped,releasing only filtered water to the
irrigation system.

The discs are stacked on the spine.The discs are color-coded FILTRATION MODE BACKFLUSH MODE
by micron size and are assembled according to your water
filtration requirements.The spine assembly has a spring
compression unit and an internal piston which are used to
alternately compress and release the discs during filtration and
backflush cycles.
FILTRATION MODE:
During the filtration process,the filter discs are tightly
compressed together by the spring and the differential
pressure,forcing the water to flow through the grooves and
traps of the discs.
BACKFLUSH MODE:
During backflush,the discs are uncompressed by releasing the
inlet hydraulic pressure.Multi-jet nozzles provide peripheral
spray on the loosened discs causing them to spin and release
the retained solids,which are flushed out to the drain. INLET TO DRAIN V

BACKFLUSH VALVE: 0 71 [31
The backflush valve has two built-in chambers,the N.O.filter port and the N.C.
drain port. Each port has its own valve seat,butthey share a common shaft [2 [']
and diaphragm.The valve chambers are mutually integrated units.When one
port is open,the other is closed,permitting the backflush valve to perform two 1;
modes of operation: [4 [51
Filtration Mode: The valve permits flow from the inlet manifold [6
through the filter,into the pipeline.
Flushing Mode:The valve closes the inlet manifold and opens the FILTRATION BACKFLUSH
drain port,causing reverse flow through the filter,ejecting impurities MODE MODE
via the drain port.
The backflush valve is either controlled by water pressure or a pneumatic
source.
A hydraulic command from the solenoid [11,which pressurizes the Lower AC AND OC
Control Chamber[2],forces the Diaphragm[31 actuated Plug Assembly[41 to CONTINUOUS SOLENOID OC LATCHING SOLENOID

move towards the Supply Port Seal[51,eventually sealing the valve drip tight.
This allows water flow from the filter through the Drain Port Seal[6].Venting COIL
the upper control chamber causes the line pressure,together with the Spring
[71 force,to move the valve back to filtration mode.
A manual override knob is installed on the base of all AC and DC continuous M
solenoids. During normal operation,the dot on the round brass knob should be MANUAL ON I OFF
pointing towards the brass solenoid base(down).Turning this knob 90 degrees
to the left or right will activate the solenoid and put the valve/filter into a AUTO AUTO
backflush mode.Backflushing should be maintained for 20 seconds,then the
knob can be returned to the auto position for normal irrigation.For DC latching
solenoids,the manual override green lever is in a vertical position.Turning to
the left 90 degrees will put the valve/filter into a backflush mode.
FILTRATION PROCESS:
During the filtration process,the water flows through the inlet manifold, FILTER IN
through the filters and the inlet valves.The filter water gathers in the outlet o FILTRATION MODE
manifold and flows into the system.

BACKFLUSH PROCESS:
The backflush process begins with an electrical command from the control unit to the first sole-
noid activated bythe pressure difference between the inlet and outlet or bytime. The solenoid
then sends a pressure command to the backflush valve,moving it from the filtration mode to the
backflush mode.
Filter#1 is then backflushed with water from the outlet manifold that has been filtered by the other
filters in the system.Contaminated water and impurities flow outthrough the drain manifold.
On completion of the allotted backflushing time,the controller releases the backflush command,
and Filter#1 returns to the filtration mode.Filter#2 then enters the backflush mode,and the process
is repeated until all the filters in the system have been backflushed.After all the filters have been
backflushed,the system returns to filtration mode until the next backflush cycle.

• Prior to start-up,check for any damage to the unit(system oper-
ates under pressure).
• Connect backflush drainage line. COVER CLAMP
• Standard assembly is water inlet and outlet on opposite sides of IN

• Cover clamps need to be properly closed.
• Verify the solenoids are correct as ordered before connecting the
wires to the backflush controller.
• PVC piping used for the drain manifold should be minimum 2"
diameter and not longer than 50'in length.If longer than 50',
increase the PVC pipe diameter to 3".
BACKFLUSH CONTROLLER INSTALLATION:
• Refer to the controller's handbook for installation instructions.
• Make sure that the voltage of both the solenoid unit and controller are correct.
• Set the manual operation button to automatic.
• Check that the PD hydraulic switch HIGH and LOW pressure lines are correctly connected to the appropriate ports.
• Set the starting backflush point on the PD switch 5 psi above the"clean pressure difference".
• Set the controller to a flush time of 20 seconds and a dwell time of 10 seconds.These settings may require adjustment to
conform to local water conditions.Typically,a 4 to 8 hour interval between backflushes is recommended.

FEMPPITW. rill]
NO WATER GOING THROUGH THE FILTER:
• If the system has upstream and downstream valves around the filter,check to make sure they are open. Check that field valves
are open.
• At start-up,the backflush valves need a minimum 12 psi to start working. If air is trapped in the system,close the downstream
butterfly valve so that pressure builds up at the filter.Then,slowly open the butterfly valve to allow water to flow to the field.
• Verify that the manual override buttons on all the solenoids are in the correct position.For AC and DC continuous solenoids,the dot
in the round brass knob should be pointing towards the brass base of the solenoid,not towards the black square plastic solenoid
coil.For DC latching solenoids,the green lever should be vertical.See page 6 for illustrations. If all of the manual override buttons
are in the wrong position,water will not flow through the filter.
• Make sure all vent tubes are venting to atmosphere with no back pressure.
NO BACKFLUSH OPERATION:
Check the Upstream and Downstream Pressure
• The pressure downstream of the filter needs to be at least 30 psi during backflushing.The Pressure Sustaining Normally Open
(PSNO)Valve should be set to at least 30 psi during backflushing.
Check the Command Filter
• Make sure the command filter is clean.A clogged command filter does not provide command water to the solenoids and backflush
valves and the filter will not flush.Also,make sure the 1/"or 1" ball valve in front of the command filter is open.
Check the Pressure Differential(PD)Gauge
• Make sure the PD gauge is not broken.The set point(the short needle)should be set at 5 psi.The long red needle indicates the
pressure differential at any given time.If the needle reads zero,then the discs are clean.As the red needle moves towards the
shorter(set point)needle,then the discs are getting dirty.When the two needles touch,the backflush controller will initiate a flush
cycle.
• Test the PD gauge while the water is on-disconnect the hydraulic tube from the low pressure port of the gauge(the off center
port).Water will squirt out of the tube;you can bend the tube to temporarily stop the water.The long red needle should move
quickly and touch the short needle.When both needles touch for 15 consecutive seconds,a backflush cycle will start.
• If the backflush starts,then the PD gauge is working. If there is no flush,replace the PD gauge.Re-connect the hydraulic tube to
the PD gauge.
Check if the Filter Discs are Clogged
• To check if the filter discs are clogged,turn off the water and confirm there is no pressure in the system.Open up a filter cover and
inspect the discs.If all of the filters are completely clogged,the filter will not flush.
• Remove the discs and clean—refer to the Disc Cleaning Instructions on Page 11 and 12.
• Reassemble the discs on the spine and the filter cover,then tighten the clamp.
• Initiate a backflush with the backflush controller.If the filter still doesn't flush,refer to the Check the Backflush Controller Section
below.
Check the Backflush Controller
• To test the backflush controller,initiate a backflush by pressing the black button(manual override).
• The solenoid should click and send the filter into flush mode.After 20 seconds,the solenoid should click again and end the
backflush.
• If the solenoid clicks,then the solenoid is operating and the control panel is not. If the solenoid does not click,then the solenoid
needs to be replaced
• To test the solenoids:remove the wires of the solenoid from the terminal of the control panel and connect them directly to the
power source.For DC models,touch the wires.For AC models,connect the solenoid wires to the outlet transformer wires.
• If the backflush was not initiated,check wires to verify all connections are secure.
2"AND KLP DISC-KLEEN FILTER OPERATION,MAINTENANCE AND TROUBLESHOOTING GUIDE • 13

Check the Backflush Controller(con't)
• Push the reset button on the front panel and initiate a backflush again.
• Flush a filter individually by turning the manual override of the solenoid 180 degrees. If that filter flushes,then the filter is working
hydraulically and the problem is electric.
• For DC backflush controllers,make sure the batteries are charging.Batteries should be changed every 2-3 years depending upon
frequency of filter irrigation and flushing. Use three year life 9 volt lithium or one year life alkaline batteries.
• For AC backflush controllers,make sure the transformer is still functioning and replace if needed.
• The controller panel can malfunction if exposed to moist or dusty conditions,rust,or lightning. If you suspect any of these causes,
contact the backflush controller manufacturer for inspection and possible warranty or repair.Or call Netafim USA Technical
Support at 888-638-2346 for assistance.
CONTINUOUS BACKFLUSHING:
Constant Water Flowing Out of the Drain Manifold
• If there is constant water going through the drain manifold,then one of the backflush valves is stuck in the flush position.This can
be caused by one of these three issues:
- There may be debris stuck in the drain port of the backflush valve which does not allowthe valve to return to the filtration
position. Determine which valve is flushing all of the time.Turn the manual override of the solenoid to flush and then return
the knob to filtration.Make sure the knob is exactly in the correct position. If the valve is still flushing,turn off the water.
2"LP Disc-Kleen Filter Batteries-unscrew the bonnet of the valve from the valve base body. Do not unscrew the bolts
of the bonnet. Disconnect the hydraulic tubing that is connected to the valve,disconnect the hub of the solenoid from
the coil from the solenoid and grab the sides of the bonnet with both hands and unscrew the bonnet assembly all the
way and lift out of the valve.Check for debris in the valve body.Check the rubber seal atthe bottom of the stem that is
connected to the bonnet assembly.Replace if necessary.
3"LP Disc-Kleen Filter Batteries-turn off the water and remove the entire 2"drain manifold from the back of the
backflush valves.Visually inspect the back side of all valves to see if there is debris.Startto disassemble the backflush
valve from the back by removing the large plastic union.Put the large spring or large o-ring in a secure place.Remove
the small bolt from the stem,pull out the black round piece and remove any debris.Carefully reassemble the valve and
attach the drain manifold.
- The solenoid may be stuck and not returning to filtration mode.On the Backflush Controller,switch the terminal wire(the
wire connected to terminal 1 and 2 for example)from a stuck solenoid to a working solenoid.If the problem moves with
the solenoid that is stuck,then the problem is in the solenoid.Disassemble the solenoid to clean any debris. If the problem
persists,replace the solenoid coil with a new one.
- The diaphragm of the backflush valve may be torn.To confirm,close the ball valve in front of the 3/a"or 1" command filter. If
water is still flushing from the drain manifold,the diaphragm may be torn.Turn off the water and remove all of the bolts from
the bonnet of the valve.Remove the diaphragm and inspect for tear.Replace if necessary.
Filter Completes a Backflush Cycle,Stops and Backflushes Again:
• If the filter is constantly backflushing by going through a cycle,stopping for 1 minute and backflushing again,look atthe controller
to see if the word "Alarm"is flashing.If it is,then the filter is probably clogged.
• The filter will get clogged for the following reasons:
- There was less than 30 psi on the downstream side of the filter during backflush.
- The water quality changed and became too dirty for the filter to keep up.(Check for severe algae bloom or high silt load).
- The flow rate was increased by turning on an additional valve,so the filter cannot maintain operation with the increased
flow rate.
- The diameter of the drain pipe is too long or too small or it's plumbed so that it elevates back into a reservoir.All of these will
create back pressure on the filter during the flush cycle and have a negative effect on the quality of the flush.The drain pipe
should be at least 2"diameter,notto exceed 50 feet long and free flowto a drain pit.There should not be a check valve or
gate valve on the drain pipe.
- Remove the discs from the spines and clean them manually.Refer to the Disc Cleaning Instructions on Pages 11 and 12.

FEMPPITW. rill]
NO WATER GOING THROUGH THE FILTER:
• If the system has upstream and downstream valves around the filter,check to make sure they are open. Check that field valves
are open.
• At start-up,the backflush valves need a minimum 12 psi to start working. If air is trapped in the system,close the downstream
butterfly valve so that pressure builds up at the filter.Then,slowly open the butterfly valve to allow water to flow to the field.
• Verify that the manual override buttons on all the solenoids are in the correct position.For AC and DC continuous solenoids,the dot
in the round brass knob should be pointing towards the brass base of the solenoid,not towards the black square plastic solenoid
coil.For DC latching solenoids,the green lever should be vertical.See page 6 for illustrations. If all of the manual override buttons
are in the wrong position,water will not flow through the filter.
• Make sure all vent tubes are venting to atmosphere with no back pressure.
NO BACKFLUSH OPERATION:
Check the Upstream and Downstream Pressure
• The pressure downstream of the filter needs to be at least 30 psi during backflushing.The Pressure Sustaining Normally Open
(PSNO)Valve should be set to at least 30 psi during backflushing.
Check the Command Filter
• Make sure the command filter is clean.A clogged command filter does not provide command water to the solenoids and backflush
valves and the filter will not flush.Also,make sure the 1/"or 1" ball valve in front of the command filter is open.
Check the Pressure Differential(PD)Gauge
• Make sure the PD gauge is not broken.The set point(the short needle)should be set at 5 psi.The long red needle indicates the
pressure differential at any given time.If the needle reads zero,then the discs are clean.As the red needle moves towards the
shorter(set point)needle,then the discs are getting dirty.When the two needles touch,the backflush controller will initiate a flush
cycle.
• Test the PD gauge while the water is on-disconnect the hydraulic tube from the low pressure port of the gauge(the off center
port).Water will squirt out of the tube;you can bend the tube to temporarily stop the water.The long red needle should move
quickly and touch the short needle.When both needles touch for 15 consecutive seconds,a backflush cycle will start.
• If the backflush starts,then the PD gauge is working. If there is no flush,replace the PD gauge.Re-connect the hydraulic tube to
the PD gauge.
Check if the Filter Discs are Clogged
• To check if the filter discs are clogged,turn off the water and confirm there is no pressure in the system.Open up a filter cover and
inspect the discs.If all of the filters are completely clogged,the filter will not flush.
• Remove the discs and clean—refer to the Disc Cleaning Instructions on Page 11 and 12.
• Reassemble the discs on the spine and the filter cover,then tighten the clamp.
• Initiate a backflush with the backflush controller.If the filter still doesn't flush,refer to the Check the Backflush Controller Section
below.
Check the Backflush Controller
• To test the backflush controller,initiate a backflush by pressing the black button(manual override).
• The solenoid should click and send the filter into flush mode.After 20 seconds,the solenoid should click again and end the
backflush.
• If the solenoid clicks,then the solenoid is operating and the control panel is not. If the solenoid does not click,then the solenoid
needs to be replaced
• To test the solenoids:remove the wires of the solenoid from the terminal of the control panel and connect them directly to the
power source.For DC models,touch the wires.For AC models,connect the solenoid wires to the outlet transformer wires.
• If the backflush was not initiated,check wires to verify all connections are secure.
2"AND KLP DISC-KLEEN FILTER OPERATION,MAINTENANCE AND TROUBLESHOOTING GUIDE • 13

Check the Backflush Controller(con't)
• Push the reset button on the front panel and initiate a backflush again.
• Flush a filter individually by turning the manual override of the solenoid 180 degrees. If that filter flushes,then the filter is working
hydraulically and the problem is electric.
• For DC backflush controllers,make sure the batteries are charging.Batteries should be changed every 2-3 years depending upon
frequency of filter irrigation and flushing. Use three year life 9 volt lithium or one year life alkaline batteries.
• For AC backflush controllers,make sure the transformer is still functioning and replace if needed.
• The controller panel can malfunction if exposed to moist or dusty conditions,rust,or lightning. If you suspect any of these causes,
contact the backflush controller manufacturer for inspection and possible warranty or repair.Or call Netafim USA Technical
Support at 888-638-2346 for assistance.
CONTINUOUS BACKFLUSHING:
Constant Water Flowing Out of the Drain Manifold
• If there is constant water going through the drain manifold,then one of the backflush valves is stuck in the flush position.This can
be caused by one of these three issues:
- There may be debris stuck in the drain port of the backflush valve which does not allowthe valve to return to the filtration
position. Determine which valve is flushing all of the time.Turn the manual override of the solenoid to flush and then return
the knob to filtration.Make sure the knob is exactly in the correct position. If the valve is still flushing,turn off the water.
2"LP Disc-Kleen Filter Batteries-unscrew the bonnet of the valve from the valve base body. Do not unscrew the bolts
of the bonnet. Disconnect the hydraulic tubing that is connected to the valve,disconnect the hub of the solenoid from
the coil from the solenoid and grab the sides of the bonnet with both hands and unscrew the bonnet assembly all the
way and lift out of the valve.Check for debris in the valve body.Check the rubber seal atthe bottom of the stem that is
connected to the bonnet assembly.Replace if necessary.
3"LP Disc-Kleen Filter Batteries-turn off the water and remove the entire 2"drain manifold from the back of the
backflush valves.Visually inspect the back side of all valves to see if there is debris.Startto disassemble the backflush
valve from the back by removing the large plastic union.Put the large spring or large o-ring in a secure place.Remove
the small bolt from the stem,pull out the black round piece and remove any debris.Carefully reassemble the valve and
attach the drain manifold.
- The solenoid may be stuck and not returning to filtration mode.On the Backflush Controller,switch the terminal wire(the
wire connected to terminal 1 and 2 for example)from a stuck solenoid to a working solenoid.If the problem moves with
the solenoid that is stuck,then the problem is in the solenoid.Disassemble the solenoid to clean any debris. If the problem
persists,replace the solenoid coil with a new one.
- The diaphragm of the backflush valve may be torn.To confirm,close the ball valve in front of the 3/a"or 1" command filter. If
water is still flushing from the drain manifold,the diaphragm may be torn.Turn off the water and remove all of the bolts from
the bonnet of the valve.Remove the diaphragm and inspect for tear.Replace if necessary.
Filter Completes a Backflush Cycle,Stops and Backflushes Again:
• If the filter is constantly backflushing by going through a cycle,stopping for 1 minute and backflushing again,look atthe controller
to see if the word "Alarm"is flashing.If it is,then the filter is probably clogged.
• The filter will get clogged for the following reasons:
- There was less than 30 psi on the downstream side of the filter during backflush.
- The water quality changed and became too dirty for the filter to keep up.(Check for severe algae bloom or high silt load).
- The flow rate was increased by turning on an additional valve,so the filter cannot maintain operation with the increased
flow rate.
- The diameter of the drain pipe is too long or too small or it's plumbed so that it elevates back into a reservoir.All of these will
create back pressure on the filter during the flush cycle and have a negative effect on the quality of the flush.The drain pipe
should be at least 2"diameter,notto exceed 50 feet long and free flowto a drain pit.There should not be a check valve or
gate valve on the drain pipe.
- Remove the discs from the spines and clean them manually.Refer to the Disc Cleaning Instructions on Pages 11 and 12.
