Determine the solids retention time

Reference no: EM13540187

Using the following assumptions, determine the solids retentiontime, 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%
