Denitrification is the term used for the biological reduction of nitrate to nitric ,acid,, nitrous oxide and nitrogen gas, and is used in ,wastewater, treatment for removal of nitrogen. Other technologies to which it can be compared are ammonia stripping, breakpoint chlorination and ion exchange; from which denitrification is the most cost-effective and consequently the most commonly used.
