WebAug 11, 2024 · Denitrification is the biological reduction of nitrate or nitrite and convert to nitrogen gas (N 2) in wastewater treatment processes 5. Denitrification is achieved by a broad wide range of heterotrophic facultative bacteria which use nitrate, or nitrite as their terminal electron acceptors for the oxidation of organic material. WebMar 30, 2024 · Heterotrophic denitrification (HD), reducing nitrate (NO 3 −-N) to N 2 with organics as electron donors, is currently the most widely applied biological nitrogen removal (BNR) process in municipal wastewater treatment plants (WWTP) . However, the HD process is greatly limited by the dependence of the carbon source. sawtooth national recreation area idaho usa
