Program Information
Narrative
The WWTP sludge management system consist of (2) waste sludge pumps rated
at 600 gpm each. They pump to (2) 50' 12'd gravity thickeners where the
thickening occurs. Two (2)100 gpm thickened sludge pumps send the material to
,one or both of the 2—Meter belt presses. in order to achieve pathogen and Vector
Attraction reduction Alka-line treatment chemicals are added -and sent to a mixer.
Material enters an inclined screw and discharged to a storage hopper. The final
product is then moved to a storage pad under 122' x 182' covered area. Any
leachates from the storage area are collected and returned to the head of the
WWTP for,treatment.
Final product is to be trucked in bulk to either a packaging facility or to be land
applied.
Currently there is no marketability study detailing destinations. or amounts of final
product to be distributed.
Should the City start to use the permit and start making class A sludge, Pathogen
requirements would be met by Alternative 15ANCAC 02T.1106(b)(3)(B) - Alkaline
treatment.
Similarly vector attraction reduction requirements would be achieved through
Alternative 15A NCAC 02T.1107(a)(6) — Alkaline stabilization.

Operating and Maintenance Procedures
by Willis Engineer(ng

--- .- online.;in-sequenee.- The-UV-T-monitor-should-be-engaged-and ver-ification-of-its-performance
made at some time In accordance with the manufacturer's recommendations. The
automatic mechanical / chemical cleaning systems should be activated.
Normal Operation - Under normal operating conditions a trend signal will be
supplied indicating the rate of UV output. Based on trend of this UVT change, the cleaning
system can be activated for both mechanical and chemical cleaning.
Alternate Operation — Based on the laboratory analysis of the success of the unit,
and the actual rate of flow,of effluent from the Plant, alternate procedures can be developed
for de -energizing a portion of the submerged modules and actually removing them from the
submerged position.
Emergency Operation — In the event of a failure of a module or component, the
appropriate verification of electrical checks and any necessary mechanical repairs should be
immediately undertaken.
3.8.5 Control
The- electrical systems and control monitoring devices have been designed to
monitor the trend In UV output and provide timely response to cleaning and / or replacement
of lamps.
3.8.6 Maintenance
Maintenance activities should be carried out as designated in the equipment -
operating manual. A detailed preventative maintenance schedule is located in Chapter 7 of
this Manual.
--> 3.9 Sludge Thickening
3.9.1 Purpose
The purpose of the sludge thickeners is to thicken the waste activated sludge from
the final clarifiers prior to dewatering in on the belt presses. The Thickeners are shown on
Figure 3.9-1.
3.9.2 Equipment
The sludge thickening system consists of two 50-foot diameter concrete tanks with
13-foot sidewater depth, each outfitted with a rotating thickener mechanism that enhances
the gravity thickening of the waste sludge material and enables the decant of the
supernatant over the effluent weirs.
Willis Engineers 3-23 City of Hendersonville WWTP
May 2002 Operation and Maintenance Manual

DRAFT
3.9.3 Relationship to Adjacent Units
Waste to the sludge thickeners comes from the waste sludge. pumping station
through two 8-Inch force mains. Thickened sludge is withdrawn from the thickeners for
chemical conditioning and application to the belt presses.
3.9.4 Operation
Start-up Procedure — Before starting up the thickeners, verification should be made
of the following:
• Check the bases to be sure that all debris. such as rocks, concrete, and the
like have been removed.
• Assure that equipment is properly aligned and leveled and that all scraper
blades are properly installed.
• Check the position of the,weirs to assure that they are level and will allow for
equal flow distribution.
• Check out all components of the thickener drive mechanisms including
confirmation of lubricants, direction of rotation, and activation of torque
overload sensing devices.
The operator should follow the manufacturer's instructions closely in placing the
thickener and appurtenant equipment into operation. Prior to admitting sludge flow, the
skimmer and collector mechanisms should be run for two or three hours with the thickener
empty to assure proper operating clearances and performance. After a complete inspection,
the thickener tank should be filled with clear water and the wasting of sludge can
commence.
Normal Operation — Under normal operating conditions waste sludge will be
discharged to the thickeners at substantially the same rate as the thickened sludge is
withdrawn. As experience is gained on 'the rate of consolidation of the sludge in the
thickeners, this procedure can be modified to gain the optimum results of alternate use of
the thickeners and control of the output to the belt presses. Sludge output from the
thickeners will go through one of the three belt press feed pumps and two comminution
devices located in the thickener building. The thickened sludge_ is pumped to the
Dewatering Building for dewatering.
Alternate Operation — In the event one unit needs to be taken off line, the piping in
the Thickener Building is configured to allow the belt press feed pumps to be utilized In
pumping from one thickener unit to another.
Emergency Operation — In the event both thickeners are inoperable, the piping in
the Thickener Building is configured to allow waste sludge to be pumped directly to the

- -- - ------sludge-belt-press,—This-should-only4ake=place-under-emergency-situations-and-only-after -
thickeners are full and recycling of waste sludge is exhausted.
3.9.5 Control
Control of the thickener units relates to assuring proper speed of the rotating
mechanisms, no excessive torque on the drive assembly, and prevention of excess solids in
the tank overflows. All other control elements related to the sludge process are discussed in
the sludge dewatering section of the Manual.
3.9.6 Maintenance
Thickeners should be inspected daily for overheating, excessive noise, and general
appearance. The decant launder should be inspected for excess buildup of solids and
cleaned as necessary. A detailed preventative maintenance scheduled Is located in
Chapter 7 of this Manual.
3.9.7 Operational Problems
With appropriate. daily inspection and preventative maintenance activities, the
thickener units should be relatively free of operational problems.
3.10 Sludge Dewatering
3.10.1 Purpose
The sludge dewatering system is intended to remove excess water from the
thickened sludge.
3.10.2 Equipment
The major components of the dewatering system are the two 2.0 meter continuous
belt filter presses located in the press room of the dewatering building. Each unit has a
nominal capacity of 90 gallons per minute and extracts water from the sludge after
conditioning it with polymer and conveying it on a belt . through a series of rollers and
presses. The layout of the two filter presses and appurtenant equipment is shown on Figure
3.10-1.
Support equipment for the belt press includes sludge feed pumps, polymer / sludge
mixing chamber, and washwater pumps.
The polymer feed system (subsection 3.11) is closely related to the sludge
dewatering system. The application and feeding of the appropriate quantity of polymer is a
necessary support function for proper belt press performance.

Operation and Maintenance Manual

3.10.3. Relationship to Adjacent Units
Sludge Is conveyed from the thickeners to the belt presses.through a belt press feed
pump unit and comminutor for each of the two presses.. A third feed pump is provided in
standby position and is valved into the sludge piping to be used in lieu of either of the two
primary belt pumps. The thickened sludge from the belt presses is discharged onto a
conveyor and is carried to the solids processor unit in the sludge building. Supernatants /
decant from the. belt presses is discharged to the plant process sewer system and returned
to the wetwell of the plant influent pumping station.
3.10.4 Operation
Start-up Procedure — Prior to placing the belt presses and their appurtenances into
operation, the following checks should be performed:
• Confirm that all construction debris and materials have been removed.
• Check all equipment for proper installation including alignment, rigidity,
foundation mountings, belt tension, belt tracking and alignment devices
functioning, and the like.
m Check all process piping for proper alignment and tight connections and all
valves for correct open / close status.
• Inspect electrical connections and power control.devices.
• Confirm the functioning of the control system.
When all of the above checks have been completed in accordance with the
manufacturer's recommendations, the individual belt presses can be started and run in a
prewash cycle. After initial running with no apparent problems, sludge may be Introduced to
the belt press for dewatering.
Normal Operation — Under normal operating procedure, the belt feed pumps will
draw sludge from the thickener, discharging it through the comminutor and then to the
mixing zone for introduction of polymer. The sludge / polymer mixture proceeds through the
belt press and the dewatered sludge is deposited on the conveyor belt that conveys the
sludge to the processing room. All controls for the belt press and related equipment are
located in the Control Room of the Dewatering Building, and are intended to perform
automatically once proper start-up settings have been activated.
Alternate Operation — One or both belt presses can be operated'at a time. Rates of
feeds can be varied, as can dosages of polymer. The controls for the system can be
operated manually or in the automatic mode.
Emergency Operation — No emergency procedures are defined. In the event that
both belt presses are inoperable, corrective measures should be undertaken immediately. If
both thickeners are full, wasting of sludge should be discontinued, and the valve between

— the two wetwells in the recycle t waste sludge pump station can be opened to enable _
recycling of the heavier sludge combined with the returned sludge to the mixed liquor.
3.10.5 Control
Flow of the thickened sludge is controlled by the valves on the .piping from the two
thickeners. Sludge may be withdrawn from either thickener. The feed rate is controlled by
the variable speed pumping equipment on each of the three pumping units. There is also
variable speed control for the polymer feed pumps. The signals for the running status and
alarms for the whole sludge dewatering system are indicated in the Control Room of The
Dewatering Building and interconnected to the Plant master control system.
3.10.6 Maintenance
The lubrication and maintenance recommendations of the various equipment
manufacturers should be followed by the operating staff. These recommendations are
contained in the manuals. provided by the manufacturers. "Good housekeeping" and
complete cleanup at the end of dewatering cycles Is mandatory. A detailed preventative
maintenance schedule is located in Chapter 7 of this Manual.
3.10.7 Operational Problems
There are several potential problems that may be encountered in the operation of the
sludge dewatering system summarized as follows:
• The characteristics of. the thickened sludge may vary widely from time to time
based on the variables of the biological process taking place in the aeration
basin.
• Changes in sludge characteristics may prescribe changes in polymer
conditioning, both in the type polymer and the dosage rate. Periodic evaluation
of polymers should be undertaken to assure that optimum performance Is being
pursued.
• The correct sludge feed rate may vary both with the nature of the sludge and the
polymer. Periodic varying of the feed rate will confirm that optimum performance
is being accomplished.
Mechanical problems with the equipment may occur from time to time. There are
many mechanical components and each requires proper maintenance and care. Attention
to the details suggested by the manufacturers manuals should minimize mechanical
problems and avoid downtime.

3.11.4 Operation
Start-up Procedure — Before placing the polymer feed system into operation after
original installation or repairs, the operating personnel should perform the following checks
to ensure proper operation:
• Check the pumping units and area around the polymer system for foreign
materials that must be removed prior to operation.
• Inspect all piping connections for proper tightness.
• Check all valves for proper operation.
• Inspect electrical connections to assure proper connections.
Normal Operation — Under normal operation, polymer will be fed as a conditioner
for thickened sludge at the belt press units. The polymer system feeds polymer to a mixing
chamber at the belt press. This mixing chamber combines the polymer with the thickened
sludge.
Investigation should be undertaken by the operating staff to confirm that the polymer
being fed is the best for application. From time to time due to changes in the influent flow, it
will be desirable to vary the dosage or to change the types of polymer used.
Alternate Operation — Alternate operation would include the use of different
polymers and different application rates.
