A high-rate activated sludge system was designed, constructed and operated at the City of Chino as a biological treatment system utilizing the maximum growth-rate potential of activated sludge as a means of removing organic, and possibly inorganic, materials from domestic wastewater. Operating results indicate that full-scale systems can be operated at high growth rates and high substrate loading rates with concomitant high substrate removal velocities and high quality effluent. Substrate loading rates as high as 3.6 (mg BOD)/(mg MLVSS) (day) and effluent BOD as low as 5 mg/l were achieved. A kinetic description indicated a yield coefficient of 0.92 (mg MLVSS produced)/(mg BOD removed), a decay constant of 0.027/day and a half-saturation constant of 26 (mg BOD)/1. The significance of these kinetic characteristics in process design and operational control is presented. Four solids separation systems--vibratory screens, enhanced gravity separation, dissolved air flotation and hydro-centrifugal cleaned screens--were tested for activated sludge solids separation.
