Webbemploys activated sludge for biological nitrification and denitrification. This consists of a nitrification process that uses nitrifying bacteria to oxidize all of the ammonia (NH 4) in wastewater to nitrate (NO 3), followed by a denitrification process in which nitrifying bacteria convert this nitrate and organic matter to nitrogen gas (N 2). WebbExactly the problem at large scale is that, You can't increase pH beyond 7.5 in order to strip ammonia by shifting wastewater pH to alkalinity. Also, following the nitrification denitrification ...
