Nitrogen is removed by nitrification and denitrification: During nitrification, ammonium is transformed to nitrite With all the addition of anaerobic bacteria and oxygen – after which to nitrate in a very 2nd stage.
The 2 most often employed processes are activated sludge (aerated ponds) and filter beds (sewage tricked about aggregate), exactly where ‘excellent’ microorganisms while in the sludge/combination break down the pathogens from the wastewater.
