A laboratory activated sludge system was operated to confirm field investigations which indicated that a 423-gallon recirculating activated sludge system could adequately treat the undiluted human wastes from 10 men for at least six months and provide an effluent acceptable for use as a flushing fluid. In addition, the level and the effects of overloading were noted. The effect of high pH on odor production was observed, and the importance of pH control between 6 and 7 was demonstrated. The feed COD of 44,000 mg/l (BOD= 21,000 mg/l) was reduced by about 90 percent and the estimated water savings for toilet flushing was estimated at greater than 90 percent.
