What is nitrification and denitrification in wastewater treatment?

Nitrification is a biological process that converts ammonia to nitrite and nitrite 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.

Untreated domestic wastewater contains ammonia. Nitrification is a biological process that converts ammonia to nitrite and then to nitrate. If standards require that

By PL McCarty · 2018 · Cited by 93 — When nitrification/denitrification is used, an anoxic tank is now commonly used first and the nitrate formed by nitrification later is recycled back to

The removal of nitrogen by biological nitrification and denitrification is a two-step process. In the first step (nitrification), ammonia is converted aerobically to nitrate (

Denitrification is […] employed to convert the nitrate-nitrogen in the effluent from the activated sludge-nitrification process into nitrogen gas.

It seemed at the time that operators needed a little extra reference material about nitrification and denitrification that they did not get from the required coursework

By PY Yang · Cited by 16 — In general, the nitrification and denitrification processes can be applied for the removal of nitrogen contained in the wastewater. The concentration of nitrogen in
