WebOptimum pH values for denitrification are between 7.0 and 8.5. Denitrification is an alkalinity producing process. The biological reduction of nitrate (NO 3) to nitrogen gas (N 2) by facultative heterotrophic bacteria is called denitrification. Heterotrophic bacteria need a carbon source as food to live.
Webammonia. 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. One treatment system used for denitrifying wastewater effluent is the
