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. The effluent concentration is desired to be
100 mg/l. If the residence time is 2 h in the sedimentation tank, determine the
volume of the sedimentation tank and cell concentration in the effluent of the
sedimentation tank.
