Determine the solids retention time (SRT) using the data below. Use th retention time equation that uses combined aeration tank and final clarifier vo- estimate system solids. Aerator volume = 250,000 gal MLSS=2750 mg/L Final clarifier volume = 110,000 gal WAS SS = 5410 mg/L Population equivalent flow = 2.35 MGD Secondary effluent (SS) = 16 mg L WAS pumping rate = 19,200 gpd

Q1 Determine the solids retention time (SRT) using the data below. Use th
retention time equation that uses combined aeration tank and final clarifier vol
estimate system solids.
Aerator volume = 250,000 gal
MLSS=2750 mg/L
Final clarifier volume = 110,000 gal
WAS SS=5410 mg/L
Population equivalent flow = 2.35 MGD
Secondary effluent (SS) = 16 mg/L
WAS pumping rate = 19,200 gpd
