Description

Wastewater operators worldwide are looking for ways to achieve reductions in their carbon footprint towards climate neutrality. Process emissions of Nitrous Oxide (N2O) from biological processes are often considered the largest single contributor with a significant potential for mitigation through running processes more efficiently. The presentation will highlight how real time measurements lead to in depth process understanding. This knowledge can be used to adjust process parameters within the constraints of the reactor at hand and considering seasonal variability. Examples from mainstream Nitrification/Denitrification, SND and sidestream Deammonification processes with N2O emission reductions of 50-80% will be presented. While knowledge from specific process configurations cannot always be transposed onto other processes, there are general strategies to be highlighted. The presentation will further inform on validation of full plant emission models and recent measurements from the Netherlands on variability N2O patterns in a long aeration lanes reactor.
