A 1.0-mgd (3,785-cu m/day) wastewater treatment plant designed for biological phosphorus removal within an activated sludge system was evaluated over a variety of operating conditions during its first year of operation. A maximum phosphorus removal rate of 0.026 lb of phosphorus removed/lb of COD removed was obtained. High influent phosphorus concentrations reruced the plant's probable performance to less than 50 percent phosphorus removal at optimum conditions. Phosphorus removal apparently occurs through a combination of metabolic and physical-chemical mechanisms. The specialized plant design has caused several operating problems, and capital and operating expenditures are significantly greater than those reported for conventional activated sludge treatment.
