Nitrification explained
WebbNitrification is a process that converts ammonia into nitrate by bacteria. Initially, the ammonia is converted to nitrite (NO 2 − ) by the bacteria Nitrosomonas , or Nitrococcus , etc., and then to nitrate (NO 3 – ) by … Webb"Nitrifying bacteria are pretty specialized. Several species live in our treatment plants, and this culture grows when the mixed liquor suspended solids (MLSS) environment is favorable to them. One species, nitrosomonas, can use oxygen during the oxidation of ammonium to a compound called nitrite.

Nitrification is the biological oxidation of ammonia to nitrite followed by the oxidation of the nitrite to nitrate occurring through separate organisms or direct ammonia oxidation to nitrate in comammox bacteria. The transformation of ammonia to nitrite is usually the rate limiting step of nitrification. … Visa mer Ammonia oxidation The oxidation of ammonia into nitrite (also known as nitritation) is performed by two groups of organisms, ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea Visa mer Both steps are producing energy to be coupled to ATP synthesis.
