Ammonia nitrogen definition

Ammonia nitrogen means the measure of nitrogen in wastewater determined in a laboratory by measuring ammonia plus organic nitrogen after digestion to convert it to ammonia nitrogen (also known as Total Kjeldahl Nitrogen).

Ammonia nitrogen means the quantity of ammonia nitrogen expressed in milligrams per liter (mg/l) as analyzed according to analytical methods described in Wisconsin Administrative Code NR 219. Ammonia nitrogen is naturally present in wastewater. Ammonia nitrogen is produced largely by deamination of organic nitrogen containing compounds and by hydrolysis of urea.
