Bellaire Wastewater Treatment Facility
Superintendent- Russ Fillmore
The Bellaire wastewater treatment facility is a system composed of separate processes or unit
operations. Each unit has a unique role in the overall treatment for converting the municipal
wastewater to (a) a liquid suitable for application to the wetlands and (b) bio-solids suitable
for injection into agricultural farmland.
1. Flow-Metering:
Electromagnetic flow meters measure flows at three different stages of the operation.
(A). Influent, from the collection system
(B). Secondary Effluent, from the ponds to the treatment plant.
(C). Final Effluent, from the plant to the wetlands
All flow data is recorded in the office.
2. Aerated Lagoons:
There are three lagoons; the first two have dividers, which are used to divide their respective lagoons in half, thereby making the detention time as long as possible.
The first two lagoons are aerated which serve as reactors for physical and biological treatment of the wastewater. The dissolved oxygen content of the wastewater rises upon contact with the air bubbles from the aerator. This helps microorganisms to assimilate the wastewater nutrients, converting them to biomass, which settles to the bottom of the lagoons.
3. Chemical feed system:
Wastewater from the far end of the third lagoon is pumped to the tertiary treatment building for additional treatment. A coagulant (alum) is added for phosphorus removal. The alum is added ahead of an inline static mixer prior to interning the clarifiers. Polymer is added to the flow to improve floc agglomeration making them large, heavy particles, which are easily settleable
4. Clarifiers:
Two 16ft. diameter by 12ft. high, steel tank up flow type clarifiers with influent flow control valves are housed in the tertiary treatment building. Each clarifier is designed to process the average daily flow. The purpose of the clarifiers is to settle the chemical floc formed by chemical addition. The chemical is a coagulant that precipitates phosphorus out of the wastewater. The floc (or sludge) is collected at the bottom of the clarifiers, which is scraped and collected in the sump in the center of the clarifier. This sludge is then pumped back to the influent line going to the lagoons.
5. Effluent Discharge:
Overflow from the clarifier receives additional treatment in a gravity sand filter. This tertiary filter system utilizes a modified rapid sand filtration process. The system incorporates automatic backwashing and an operation for periodical removal of grease and oil deposits.
6. Irrigation System:
The clarified and filtered treatment effluent is pumped from a clearwell in the tertiary filter to a wetlands area for disposal. The irrigation area consists of 100 acres of wetlands, which is divided into four 25-acre areas, which enables alternating use of the areas. The treated wastewater is discharged from a system of above-ground piping into areas blanketed with geotextile fabric to minimize soil erosion and channeling.
Did you ever wonder how we decided to plow the road and where yours fall in the time table? Below is how we prioritize our plowing. Please be aware we start plowing around 4:00 AM during snow times. This is necessary to make sure all the roads are done for the morning commute and school busses.
Streets Plowed and Sand Priority
PRIORITY ONE: M-88, West Cayuga, East Cayuga, Derenzy, Broad Street, West Forest Home
PRIORITY TWO: South Genesee, North Genesee, Antrim Street, Park Street south of Forest Home, Durham, Seneca, West Broad, Mount and Stueben Street
PRIORITY THREE: Park Street north of Forest Home, West Hastings Street. These are for school traffic and must be taken care of for regular schooldays and special evening functions.
PRIORITY FOUR: All other Village streets and parking lots
PRIORITY FIVE: Sidewalks stating with downtown both sides including walking path along bar. then north along M-88 on the north side to party store then south side to Beech Street. Then Bridge Street south of M-88 both sides to State Street.
