Using the following assumptions, determine the solids retention time, the cell wastage flow rate, and the return sludge flow ratefor the Jambalaya shrimp processing plant WWTP
Assumptions:
Allowable BOD5 in effluent = 25.0 mg/l
Suspended solids in effluent = 30.0 mg/l
Wastage is from the return sludge Line
Yield Coefficent = 0.50 mg VSS/mg BOD5 removed
Decay rate of microorganisms = 0.075 d^-1
Inert Fraction of suspended solids = 30.0%
