Two activated sludge aeration tanks at Turkey Run, Indiana, are operated in series. Each tank has the following dimensions: 7.0 m wide by 30.0 m long by 4.3 m effective liquid depth. The plant operating parameters are as follows:
Flow = 0.0796 m3/s
Soluble BOD5 after primary settling = 130mg/L
MLVSS = 1.500 mg/L
MLSS = 1.40 (MLVSS)
Settled sludge volume after 30 min = 230.0 mL/L
Determine the following: aeration period, F/M ratio, SVI
