Total Kjeldahl Nitrogen (TKN) is the U.S. EPA-approved parameter used to measure organic nitrogen and ammonia. The TKN content of influent municipal wastewater is typically between 35 and 60 mg/L. Organic nitrogen compounds in wastewater undergo microbial conversion to NH3 and ammonium ion NH+ 4. Ammonium ion is the first inorganic nitrogen species produced during biological wastewater treatment.
Overview of Nonprotein Nitrogen Poisoning. (Ammonia toxicosis) Poisoning by ingestion of excess urea or other sources of nonprotein nitrogen (NPN) is usually acute, rapidly progressive, and highly fatal. NPN is any source of nitrogen not present in a polypeptide (precipitable protein) form. Sources of NPN have different toxicities in various species, but mature ruminants are affected most commonly.
