Determine the sludge age and cell wastage flow rate

Reference no: EM13305561

Using the following assumptions, determine the sludge age and cell wastage flow rate. Assume: Suspended solids in effluent negligible Wastage is from aeration tank Yield coefficient = 0.4 Bacterial decay rate = 0.04 1/d Effluent BOD5 = 10mg/L F/M = 0.33 mg/mg*d BOD5 after primary settling = 150mg/L MLVSS = 1700mg/L MLSS = 1.4(MLVSS) Q = 0.0796m3/s V = 1806 m3 Aeration period = 0.5 1/d
