A WWTP with activated sludge secondary treatment receives 0.290 m / s of flow from the primary clarifier. There is a concentration of microbes in the aeration basin of 2500 mg VSS/L. The return sludge has a concentration of 11,000 mg VSS/L. The concentration soluble BOD from the primary clarifier is 200 mg BODs/L. The yield is 0.49 mg VSS/mg BOD 5. The solids residence time is 10 days. The effluent soluble BOD concentration is 5 mg BODs/L. The decay coefficient is 0.1 1/d. What is the volume of the activated sludge tank?

A complete-mixed activated sludge process is to be designed to treat 5.0 MGD of primary effluent having a BOD5 of 180 mg/L. The requirement is that the effluent BOD5 and TSS concentration be 20 mg/L or less on an annual average basis. The following biokinetic coefficient obtained at 15°C: Y = 0.6 mg VSS/mg BOD5, k=2.85d-¹, Ks = 70 mg/L BOD5, and kå = 0.041 d¹¹. Assume that the MLVSS concentration in the aeration basin is maintained at 2,500 mg/L. Determine: a. The minimum MCRT (d) b. The MCRT necessary to meet the requirement (d) C.
