Reducing nitrous oxide emission in wastewater systems by pathway regulation (2015–2018)

Abstract:
Nitrous oxide (N2O) is a potent greenhouse gas that can be produced during biological nitrogen removal in wastewater treatment systems. N2O emissions primarily occur in aerated zones due to active striping and ammonia-oxidizing bacteria (AOB) are the major contributors to N2O production under such conditions. The project will carry out the first ever systematic study on N2O production by AOB in mixed culture wastewater treatment systems. It will not only advance the fundamental knowledge on N2O production pathways by AOB under different operational conditions, but also deliver a modelling tool for reliably estimating N2O emission from wastewater treatment systems as well as strategies to reduce the emissions.
