The development of design criteria for a waste water treatment plant is described. Operating results for a laboratory activated sludge unit, a Dowpac trickling filter pilot plant, and an aero‐accelator activated sludge pilot plant are given. Studies with the aero‐accelator pilot unit indicated that by observing certain critical nutrient and dilution requirements the industrial effluent, containing toxic 2,4‐D waste water, could be satisfactorily treated by bio‐oxidation. A phenol removal of 99% and a biochemical oxygen demand (B.O.D.) removal of 90% to 95% was obtained. In the full scale treatment plant, the estimated cost of operation was calculated at $0.50 per pound of phenol removed, and $0.08 per pound of B.O.D. removed.
