ABSTRACT:
A nitrification process is disclosed wherein the population of the nitrifying bacteria in an activated sludge system may be increased by the addition of ammonium nitrogen to a return sludge reaeration zone. The increased nitrifying population results in increased reliability of nitrification and lower effluent ammonium nitrogen concentrations.
