Brewerton

Area served: Brewerton and Town of Cicero (Lakeshore from Brewerton to Bridgeport).

Treatment: Secondary treatment using contact stabilization modification of the of activated sludge process. Design volume = 3.0 MGD (peak = 7.5 MGD). Fine bubble diffusers are used for the aeration system. Total phosphorus is removed year-round.

Plant facts

The effluent is seasonally disinfected with sodium hypochlorite.

Typical influent: Volume = 1.82 MGD
BOD₅ = 102 mg/L
TSS = 196 mg/L
TP = 5.6 mg/L
TKN = 25.6 mg/L (from 2002 Laboratory Analysis Data).

Both sides are operated full time. Upgraded in 2001 with an IDI screen rake, a rotary drum thickener, and duckbill coarse bubble diffusers to aerate the south digester.

Principal chemicals used

Sodium hypochlorite at South Bay Pump Station for odor control (May to October); also for disinfection at plant (May-October). Ferrous sulfate for phosphorus removal. Cationic polymer used for settling enhancement in the final clarifiers. Cationic and anionic polymer to condition biosolids to be processed in the rotary drum thickener.

Biosolids handling

Two aerobic digesters operated in series. A piping modification allows biosolids to be transferred from the north to the south digester. Biosolids are processed with a rotary drum thickener, stored in one concentration tank, then hauled by tanker to Metro for addition to anaerobic digesters, dewatering, and treatment by the N-Viro™ process.
