This study was undertaken in order to obtain operation and design information necessary for the successful functioning of municipal wastewater treatment plants to accomplish carbon, nitrogen, and phosphorus removal. Investigations were carried out on continuous flow bench-scale pilot systems using municipal wastewater. The continuous flow studies involved a one-stage nitrifying system, a three-stage nitrifying-denitrifying system, and a combined biological nitrogen-phosphorus removal system. The first two systems were operated simultaneously. These systems were operated under different sludge retention times and food-to-microorganism ratios. The hydraulic flow rates were carefully controlled throughout all experiments. These data were then used to evaluate the systems for organics, nitrogen, and phosphorus removal.
