Where does nitrogen come from in wastewater
The majority of the nitrogen contained in raw sewage (urea and fecal material) is converted from organic-nitrogen to ammonia (NH3) as it travels through sewer pipes.
As a result, most of the influent nitrogen is ammonia (NH3), although some organic-nitrogen remains.
Ammonification is mostly an anaerobic process..
