With the ever increasing effluent quality requirements, nutrient removal, particularly nitrogen removal, from domestic and industrial wastewater is becoming of some concern. From all present indications substantial removals of nitrogen will become mandatory in many watersheds in this country. This research was directed toward the use of the inherent capabilities of the activated sludge biological treatment method to remove nitrogen by encouraging increased synthesis. Through this mechanism the nitrogen is removed in the cell mass. Four batch biological reactors were run for fourteen weeks to investigate the feasibility of this process. The units were fed a synthetic wastewater and operated under varying conditions. An overall assessment of the process was made by monitoring the various forms of nitrogen added to, and removed from, the units.
