Using the following assumptions, determine the sludge age, cell wastage flow rate, and return sludge flow rate for the Turkey Run WWTP. Assumptions: Q = 0.0796 m/s X = 1500 mg/L So = 130 mg/L 2 Aeration tanks (7.0 mW x 30.0 m L x 4.3 m H) Suspended solids in the effluent are negligible. Effluent BODs = 5.0 mg/L (soluble) Return sludge concentration = 9130 mg/L Bacterial decay rate = 0.040 day-1 Y=0.40 SRT = [a] days Waste sludge flow, Qw = [b] m3/d Return sludge flow, Qr = [c] m3/d
