The aeration tank for a completely mixed aeration process is being sized for a design wastewater flow of 4500 m³/d. The influent COD is 150 mg/L. The design effluent COD is 7 mg/L. Recommended design parameters are a sludge age of 10 days and MLVSS of 1400 mg/L. The expected Sludge Volume Index is 100 ml/g. The selection of these values takes into account the anticipated variations in wastewater flows and strengths. The kinetic constants from a bench-scale treatability study are Y = 0.60 mg VSS/mg COD and ke = 0.06 per day. Calculate: a. the hydraulic residence time and volume of the aeration tank b. the food/microorganism ratio c. the sludge production rate d. the sludge recycle ratio e. the oxygen requirement
