A complete mix activated sludge process is to be used for biological treatment. This plant receives 10,000 m³ of wastewater per day with BOD loading of 250 mg/L. The primary treatment efficiency is 25%. Assume the followings: Determine the followings: (i). (ii). -4- Plant effluent BOD5 = 12 mg/L Biomass yield = 0.54 kg biomass / kg BOD Endogenous decay rate = 0.05 day-¹ Solids Retention Time = 8 days MLVSS concentration in the aeration tank = 2,700 mg/L Waste and recycle solids concentration = 12,000 mg/L The hydraulic detention time in hours. The aeration tank volume in cubic meters. ...4/- SULIT EAP582
