A three-stage activated sludge system with mineral addition for nutrient removal was operated with District of Columbia primary effluent. Influent flow followed a programmed diurnal cycle and averaged 205 Cu m/day (54,000 gpd). The first biological reactor was operated as a modified aeration system with ferric chloride addition for supplemental phosphorus removal. The clarified effluent then flowed to the second reactor for the biological nitrification of ammonia and organic nitrogen. Dry lime was used for pH control. Methanol was added to the nitrified effluent, and biological denitrification occurred in the final activated sludge system. Prior to clarification, the denitrification effluent was briefly aerated for nitrogen gas removal and for consumption of any excess methanol. The clarified effluent was then split into two equal streams for comparison of filtration performance of a dual-media coal and sand filter with that of a multi-media coal, sand, and ilmenite filter. Effluent quality consistently met the proposed D. C. discharge standards of BOD = or < 4.5 mg/l; total N = or < 2.5 mg/l; and P = or < 0.22 mg/l.
