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 further processing.
