WebAug 22, 2013 · Nitrification is the oxidation of ionized ammonia (NH 4 +) to nitrate (NO 3-) and is performed by nitrifying bacteria when the ORP of the wastewater is +100 to +350 mV. ... Wastewater plants conduct biological phosphorus removal to meet total phosphorus discharge limits. The process consists of two treatment steps - first, … Webnitrogen to nitrates via nitrification, and the subsequent elimination of nitrogen through denitrification. Because nitrification typically only occurs following carbonaceous biological oxygen demand (BOD) removal, the limiting factor for effective ddenitrification is often the absence of a readily biodegradable carbon WebBiological Denitrification: Untreated domestic wastewater contains ammonia. Nitrification is a biological process that converts ammonia to nitrite and then 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. エクストリーム 人材
