Deliberate Use of Process
Denitrification is commonly used to remove nitrogen from sewage and municipal wastewater. It is also an instrumental process in wetlands and riparian zones for the removal of excess nitrate from groundwater resulting from excessive agricultural or residential fertilizer usage.
Reduction under anoxic conditions can also occur through process called anaerobic ammonium oxidation (anammox):
- NH4+ + NO2− → N2 + 2 H2O
In some wastewater treatment plants, small amounts of methanol, ethanol, acetate or proprietary products like MicroC 1000 or MicroC 2000 are added to the wastewater to provide a carbon source for the denitrification bacteria. Denitrification processes are also used in the treatment of industrial wastes.
