Accounting

Problem 1. A biological reactor with no influent bacteria must be operated so that an influent BOD of 600 mg/L is reduced to 10 mg/L. The kinetic constants have been found to be: KS = 500 mg/L, m = 4 d-1. If the flow is 3 m3/d, how large should the reactor be (if you neglect bacteria death)?

Problem 2. Given the conditions for Problem 1, if the only reactor available has a volume of 24 m3, calculate the percent reduction in substrate concentration achieved by the CSTR.
