Calculation organic nitrogen wastewater
WebA significant amount of nitrogen can be found in domestic wastewater. The exact concentration depends on protein application of the population. Usually about one-third of total nitrogen are organic nitrogen compounds, mostly urea. The remainder are ammonium salts. Domestic wastewater generally contains no more than 3% nitrates and … WebIt leads to the formation of nitrogen gas (nitrogen N2) starting with organic nitrogen, and passing by: ammonia, nitrite, nitrate. In wastewater treatment plants, several forms of nitrogen are present: Nitrites and nitrates: oxidized nitrogen; the non-oxidized states: Kjeldhal nitrogen including organic nitrogen and ammoniacal nitrogen (NH4+)
