A continuous process is set up for treatment of wastewater. Each day, 10⁵ kg cellulose and 10³ kg bacteria enter in the feed stream, while 10⁴ kg cellulose and 1.5 x 10⁴ kg bacteria leave in the effluent. The rate of cellulose digestion by the bacteria is 7 x 10⁴ kg d^-1. The rate of bacterial growth is 2 x 10⁴ kg d^-1 ; the rate of cell death by lysis is 5 x 10² kg d^-1. Write balances for cellulose and bacteria in the system.
