A modified activated sludge process that includes both carbonaceous and nitrogenous oxidation to reduce high levels of ammonia in petrochemical waste water was studied in a pilot plant design. Dissolved oxygen, pH, temperature, and sludge age were controlled and measured. Ammonia concentration in the petrochemical waste water used as the influent waste to the pilot plant was maintained up to 390 mg/L. Adaptation of the activated sludge biomass to the influent was accomplished with step-function shock loading. Subsequently, operation in the zero sludge wasting mode resulted in a low excess sludge production rate and the minimization of nitrifier washout and high percentage removals of ammonia, COD, BOD, and sulfide were measured.
