ABSTRACT:
A process is disclosed to improve the efficiency of nitrification in activated sludge systems. Supplemental ammonium nitrogen in the form of anhydrous ammonia or an aqueous solution of ammonia is added to the nitrification zone preferably during periods of low flow and low loadings of oxidizable nitrogenous compounds. The ammonium nitrogen addition is controlled by monitoring the ammonium nitrogen concentration of the activated sludge mixed liquor exiting the nitrification zone. The supplemental ammonium nitrogen causes an increase in the population of the nitrifying bacteria which results in an increased capacity for nitrification. The increased efficiency obtained will result in increased reliability of nitrification and lower effluent nitrogen concentrations.
