® Conventional (Includes coagulation, flocculation, and sedimentation, usually followed by
filtration and disinfection)
❑ Ion Exchange (Sodium Cycle Cationic ion exchange)
❑ Green Sand Filter (No sodium recharge)
❑ Membrane Technology (RO, nanofiltration)
Check here if the treatment process also uses a water softener ❑
6. Description of source water(s) (i.e. groundwater, surface water)
Catawba River- Surface water
7. Describe the treatment process(es) for the raw water:
Raw water is treated with an initial dose of potassium permanganate. Alum is added.
Caustic is occaisionally added at this point as well. Water enters plant flocculators, and
the majority of dirt falls out in the sedimentation basins. Water is then chlorinated before
it is sent through dual media filters. Fluoride, Caustic, Metaphosphate, and chlorine are
dosed at appropriate levels. Water receives proper contact time in the clearwells before it
is sent out to the ditribution system.
8. Describe the wastewater and the treatment process(es) for wastewater generated by the
facility:
For active operations: Filter backwash water and basin sludge is allowed to settle in the
clarifier for a minimum of two hours. A valve is opened after proper settling time to allow
the decant to be discharged. Settled sludge is pumped out as needed (usually once a year).
Sludge is Land applied via permit WQ0019504.
Our NPDES permit is currently inactive. We send filter backwash directly to the Belmont
waste water plant. Basin water/ sludge is sent to the clarifier, allowed to settle for two
hours, and the decant is pumped to the Belmont waste water plant. Settled sludge is
pumped out as needed (usually once per year). Sludge is land applied via permit
WQ0019504.

Solids Handling Plan for the City of Belmont WTP
The wastewater from the Belmont WTP is allowed to settle in the clarifier for a minimum of two hours.
A valve is opened after proper settling time to allow the supernatant to be discharged. Settled sludge is
pumped out as needed (usually once a year).Sludge is land applied via permit WQ0019504.
The solids are settled out in the Sludge Thickener.All operators have access to the City of Belmont
Water Treatment Plant Operation& Maintenance Manual, which provides an explanation of the Sludge
Thickener and its operation in section 4.2.The description is attached to this plan as well.
Pictures of the land application process are below:

CHAPTER 4-WASTE HANDLING FACILITIES
4.2 SLUDGE THICKENER
4.2.1 Objectives and Design Basis
The objectives of the Sludge Thickener are to collect the sludge flows from the Sedimentation
Basins. to seoarate the solids and water, and to concentrate the solids for pumping to the
Centrifuge Building, or pumped out to trucks for land application.
Typically, sludge thickeners will concentrate the influent solids by two to seven times. For
example, an influent solids concentration of four percent could be thickened to a concentration
between about 8 percent and 28 percent. Solids and water separate by gravity and the solids are
allowed to accumulate in the sludge thickener. Once the thickener is full, the solids can be
pumped out to be land applied, or pumped to the Centrifuge.
4.2.2 Equipment Description
A. SLUDGE THICKENER
Construction: concrete
Diameter: 61 feet
Depth (maximum): 16 feet
Capacity: 349,400 gallons
Surface Area: 2,920 ft2
Sludge Scraper

Type: H-60LT
Collector speed: 6.13 feet/minute
Motor for Reducer
Motor Manufacturer: Baldor
Model: M3546T-5
1.5
Horsepower:
Minutes per revolution: 31.25
Speed: 1730 rpm
Voltage: 208
Amperage: 5.6
1. Equipment Characteristics
The Sludge Thickener is located east of the Clearwells next to the Centrifuge Building. The
thickener is used to collect sludge flows from the Settling Basins and drain water from the
City of Belmont 1 4.2

Clearwells. A 16-inch influent line is provided for the Sludge Thickener from a sewer manhole
near the Clearwells. The influent line discharges into a center feed well in the thickener.
The thickener is supplied with a center-mounted drive platform and center column. A walkway
is provided to access the drive platform as needed. The center feed well is suspended from th
drive platform. A drive unit is mounted on the drive platform and consists of a drive motor,
primary and secondary gear reducers, a drive cage, and a turntable that drives the scraper arm
assembly. A right-angle speed reducer is attached to the drive motor as a primary reducer. The
drive motor and primary reducer use a chain drive to rotate the secondary gear reduce. Two
torque switches are supplied for the drive unit. The switches are used to activate an alarm and
to stop the drive unit if high torque conditions develop. The drive unit rotates a drive cage that
turns the scraper arms as needed. The scraper arm assembly consists of two scraper arms
equipped with a number of scrapers and squeegees. The scrapers are angled to help pull
settled sludge to the center of the tank,
The bottom of the Sludge Thickener slopes toward the center. A sludge concentrator is
positioned in the bottom of the thickener below the center column. The concentrator is
positioned in the bottom of the thickener below the center column. The concentrator has two
paddles that are driven along with the scraper arms. The paddles are mounted 180 degrees
apart and 90 degrees from either scraper arm. Settled solids are gently mixed by paddles to
concentrate the solids and to help keep them fluidized in the concentrator.
2. Principles of Operation
Sludge from the Settling basins flows by gravity to the 16-inch thickener influent line and
enters the center feed well. The center feed well separates the influent sludge flow from
the clear supernatant in the thickener. The feed well also helps direct the influent flow
downward into the thickener. Solids and water begin to separate as the sludge settles in
the thickener. Sludge eventually settles to the bottom of the thickener, while clear water is
decanted through the effluent line.

RE: Change of NPDES Permit*NC0077763 to inactive status •
Dear Mr. Sledge:
This letter is to inform you of the City of Be cnt`s desire to _ ge NPDES . yT"NC00'7 763 to an inactive status as of July 1, 2012. We would like to divert the waste water from the Water
Treatment Plant to the Belmont Waste Water Plant for treatment.
The Water Plant's waste water can be diverted by installing 2 plugs in the lines feeding.our
thickener. The waste water then flows through the collection system to the Belmont Waste Water
Plant. Alternatively, waste water can be pumped from the thickener directly into the collection
system if needed. Pilot tests have shown no negative impacts on the Belmont Waste Water
Plant's process or effluent.
We understand that we are still responsible for the annual permit fee.
Sincerely,
Z-z____,,g.---(7
