In this paper, an extreme...
Nitrous oxide emission depending on the type of electron acceptor by a denitrifying phosphorus removal sludge
Water and wastewater treatment and reuse
Denitrifying polyphosphate accumulating organisms (DNPAOs) are very promising for simultaneous nitrogen and phosphorus removal. While during denitrification, emission of a greenhouse gas, nitrous oxide (N 2O), may occur. In this study, DNPAOs were enriched in a lab-scale reactor, and N 2O emission...
