Nitrogen is found in a large variety of compounds and forms and is considered to be the ultimate “quick-change artist”. In municipal wastewater it is mainly encountered as a waste product in the form of urea, which is already converted in part to ammonium nitrogen by ammonification. In the aeration basin, the initial step of nitrification consists in oxidizing the nitrogen present in wastewater via nitrite to nitrate, for which oxygen is required.
For fishes, ammonium is toxic in very small concentrations already. Hence, water bodies with an ammonium concentration of 1 mg/l is not suitable for fishing. Therefore, the discharge values which have to be met are very low.
