Analysis Of TKN And Ammonia In NPDES Wastewater Samples
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 NH 3 and ammonium ion NH+ 4.Ammonium ion is the first inorganic nitrogen species produced during biological wastewater treatment.

The average removal efficiencies of suspended solids, BOD 5 and ammoniacal nitrogen were 71.5 %, 50.6 % and 13.1 %, respectively. The relatively low removal efficiencies of the various bacteriological, physical and chemical parameters suggest that the hydraulic retention time was probably insufficient for optimal treatment to occur.
