treatment of ammonia nitrogen wastewater in low

Treatment of Ammonia Nitrogen Wastewater in Low

In China, the primary standard of ammonia nitrogen in wastewater is less than 15 mg/L and the secondary standard is less than 50 mg/L (Integrated wastewater discharge standard (GB 8978-1996)). The methods of chemical precipitation, blow-off, and adsorption are commonly used for the treatment of ammonia nitrogen wastewater at low concentration.

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.
