A well-mixed aeration pond with no recycle serves as the biological reactor for a small community. The pond receives 30 m³/d of influent with a BOD5 of 375 mg/L that must be reduced to 28 mg/L before discharge. The kinetic constants for this system are the following: Ks = 100 mg/L BOD5, kd = 0.10/d, Hmax = 1.6/d and Y = 0.60 mg VSS/mg BOD5. When answering the following, assume that steady-state conditions apply. a) What must the hydraulic residence time be in the pond to achieve the desired level of removal? 4 d b) What is the mass of microbes produced in the pond each day? kg VSS/d
