N-Tox® prevents activated sludge failure and monitors greenhouse gas emissions
Dr Steve Callister and Prof Tom Stephenson
A new technique for evaluating nitrification efficiency in industrial and municipal activated sludge systems is described that uses direct measurement of dinitrogen oxide, an important greenhouse gas, as an indicator of nitrification failure. Developed at Water Innovate, N-Tox® helps control ammonia levels in treated effluent by providing an early warning of wastewater treatment failure. The technology also helps plant managers control greenhouse gas emissions.
