Which statement best describes nitrification in wastewater treatment?

Explanation:
Nitrification is the aerobic biological oxidation of ammonia to nitrite and then to nitrate, carried out by specialized bacteria in wastewater treatment. Ammonia-oxidizing bacteria convert NH3/NH4+ to nitrite, and nitrite-oxidizing bacteria convert nitrite to nitrate. This process requires oxygen and happens in well-aerated zones, making it a central step in removing nitrogen from wastewater. It’s not about turning nitrate back into ammonia, nor about disinfection or settling of solids.
