WebIf the wastewater to be treated contains various forms of nitrogen, three biological treatment steps are required for nitrogen removal: (a) in a bio-oxidation step, organic nitrogen is anerobically broken down to ammonia nitrogen; (b) in a subsequent nitrification step, ammonia nitrogen in the wastewater is aerobically converted to nitrate nitrogen; … WebIn addition, biological denitrification and phosphorus removal require nitrification and denitrification under aerobic and anoxic conditions, which are difficult to achieve simultaneously in MFC, so the efficiency of MFC in removing nitrogen and phosphorus from wastewater is low [19].
WebNov 24, 2024 · Nitrogen mitigation is serious environmental issue around the globe. Several methods for wastewater treatment have been introduced, but biological denitrification has been recommended, particularly with addition of the best external carbon source. The key sites of denitrification are wetlands; it can be carried out with different methods.
