WebThe biological nitrogen removal (BNR) process is a cheap and the most widely practiced approach for nitrogen control in wastewater treatment. For many years, the traditional biological method for nitrogen removal from wastewater has been the combination of nitrification and denitrification processes. WebBiological Denitrification: Untreated domestic wastewater contains ammonia. Nitrification is a biological process that converts ammonia to nitrite and then to nitrate. If standards require that the resulting nitrate be removed, one treatment alternative is the process of denitrification, in which nitrate is reduced to nitrogen gas.
