organic ammonia when Nitrogen present in raw sewage

Answer 2

Typically, less than one percent of the nitrogen in raw wastewateris in the form of nitrates (NO3 -) or nitrites (NO2 -). ... Under the right conditions in biological treatment, a lot of the organic nitrogen is decomposed into ammonia. Certain bacteria then oxidize the ammonia to nitrite.
