Operation principle Applications The ANAMMOX® reactor is a reactor The ANAMMOX® process can be used for system in which nitritation and anammox the removal of ammonium from nitrogen conversion occur simultaneously in one rich effluents. single process unit. These effluents are found in: The natural nitrogen cycle involves various • Municipal waste water treatment biological processes. Nitritation is the (sludge rejection water) process where ammonium is oxidised to • Organic solid waste treatment nitrite and nitrification is the process (landfills, composting, digestion) in which ammonium is fully oxidised to • Food industries Anammox bacteria nitrate. Denitrification is the process which • Manure processing industry converting ammonium and nitrite into nitrogen gas. converts nitrate with addition of an organic • Fertiliser industry carbon source to nitrogen gas. Anammox • (Petro) chemical industry (anaerobic ammonium oxidation) conversion • Metallurgical industry is an elegant short-cut in the natural nitrogen • Semi-conductor industry cycle where ammonium and nitrite are converted to nitrogen gas. As the anammox process involves removal - of ammonium over nitrite (NO2 ) rather than - nitrate (NO3 ) less oxygen (O2) is required.
