Nitrification & Denitrification

Nitrification & Denitrification

Nitrification stops at a pH below 6.0. The nitrification reaction (that is, the conversion of ammonia to nitrate) consumes 7.1 mg/L of alkalinity as CaCO 3 for each mg/L of ammonia nitrogen oxidized. An alkalinity of no less than 50-100 mg/L is required to insure adequate buffering. Water temperature also affects the rate of nitrification.
