An industrial waste-water stream is fed to a stirred-tank reactor continuously and the cells are recycled back to the reactor from the bottom of the sedimentation tank placed after the reactor. The following are given for the system: F = 100 l/h; S0 = 5000 mg/l; mm = 0.25 h-1 ; Ks = 200 mg/l; α (recycle ratio) = 0.6; C (cell concentration factor) = 2; Y ^M _X/S = 0.4. The effluent concentration is desired to be 100 mg/l.  Determine the cell concentration in the reactor and in the recycle stream.
