#Section 4: Fundamentals of Biological Engineering

A continuous process is set up for treatment of wastewater. Each day, 10³ kg cellulose and 105 kg bacteria enter in the feed stream, while 10² kg cellulose and 1.5 x 10² kg bacteria leave in the effluent. The rate of cellulose digestion by the bacteria is 8 x 10² kg d^-1. The rate of bacterial growth is 4x 10² kg d^-l; the rate of cell death by lysis is 6 x 10² kg d^-1. Write balances for cellulose and bacteria in the system.
