WebbNitrification occurs in two stages: the transformation of ammonia into nitrite by oxidation then the evolution of nitrite (NO2-) into nitrate (NO3-). This is called nitritation and then nitration. Micro-organisms responsible for nitrification are Nitrosomonas and Nitrobacter.
Webb10 maj 2024 · The research revealed in the paper considers the improvement of secondary treatment of wastewater in the aerobic reactor to provide removal of organics and nutrients. There were five types of polymer biofilm carriers taken into account initially; however, two of them were decided not to apply due to technological reasons. The main part of the … WebbNitrification stops at a pH below 6.0. The nitrificaiton reaction (that is, the conversion of ammonia to nitrate) consumes 7.1 mg/L of alkalinity as CaCO3for 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.
WebbNovel technologies such as partial nitritation (PN) and partial denitritation (PDN) could be combined with the anammox-based process in order to alleviate energy input. The former combination, also noted as deammonification, has been intensively studied in a frame of lab and full-scale wastewater treatment in order to optimize operational costs and …
