10. You are to design a wastewater treatment plant for Carbondale. You should plan on your design accommodating a population of about 50,000. Determine the volume of tber activated sludge tank needed, making the following assumptions. Please give your answer in liters. (12 points) Per capita sewage output = 250 L/person-day Influent BOD to activated sludge = 150 mg/L Effluent BOD from activated sludge = 30 mg/L Operating concentration of active bacteria = 3,000 mg/L Maximum specific growth rate constant = 4 day' Monod constant = 50 mg/L Death rate constant = 0.05 day! Yield = 0.5 mg cells/mg BOD
