A perfectly mixed aeration pond with no recycle (return line) serves as the biological reactor for a small community. The pond recieves 30 m^3/d of influent with a BOD5 of 350 mg/L that must be reduced to 20 mg/L before discharge. It has been found that the kinetic constants for the system are Ks=100 mg/L BOD5, kd= .10d-1, um=1.6d-1, and Y is .60mg VSS/mg BOD5. Draw a schematic diagram showing the aeration pond with labeled input and output streams. What must the hydraulic detention time be in the aeration pond.
