nh3 reclamation unit For determining the quality

The two major factors that influence selection of the method to determine ammonia are concentration and presence of interferences. In general, direct manual determination of low concentrations of ammonia is confined to drinking waters, clean surface or groundwater, and good-quality nitrified wastewater effluent.

  • What do the units NH3-N mean? - Hach Company

    Aug 18, 2020 · Answer. Ammonia (NH3) and nitrogen, ammonia (NH3-N) are different expressions of the chemical forms of ammonia. The NH3-N form uses the molecular weight of only the nitrogen atoms. The NH3 form uses the molecular weight of the entire ammonia molecule, 1 nitrogen atom + 3 hydrogen atoms. The nitrogen-ammonia NH3-N form is common because it relates to other nitrogen compounds such as nitrogen, nitrite NO2-N or nitrogen, nitrate NO3-N.
