N2O Emissions from Wastewater Plants

Professor Mark van Loosdrecht
Chair Professor and Head of Environmental Biotechnology Section, Delft University of Technology



Wastewater treatment protects society from diseases and a bad environment as well contributes to a safe water resources management. Nevertheless, there are negative impacts of wastewater treatment that needs to be addressed. One of these aspects is the emissions of greenhouse gases. Especially the strong greenhouse gas nitrous oxide (N2O) is of concern. It is produced as a side product of the nitrogen removal conversions. In this lecture, the speaker will address the current insights and developments related to understanding the microbiological aspects of nitrous oxide formation and potential measures for prevention of these emissions.
