Meadowbrook-Limestone
Area served:
Portions of Syracuse, Village of Manlius, Village of Fayetteville,
and towns of Manlius and Dewitt.
Treatment:
Conventional activated sludge with
phosphorus removal and nitrification. Anoxic zones
added at head end of each aeration tank in 1994 for
filament control to improve settling in final
clarifiers.

Principal chemicals used
Ferrous chloride
(pH about 2) for TP removal; average monthly
FeCl2 consumption 10,600 gal. Sodium hypochlorite for
disinfection. Anionic and cationic polymer used for
solids conditioning.
Biosolids
Aerobic digester discharges biosolids at approximately
1% total solids concentration which are routed to a
decant tank to remove as much water as possible prior
to processing in a rotary drum thickener. Thickened
biosolids are hauled by tanker to Metro for further
processing.
