Greenhouse gas emissions from membrane bioreactors

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

Nowadays, it is widely accepted that wastewater treatment plants (WWTPs) aresignifcantly contributing to anthropogenic sources of greenhouse gas (GHG)emission. Among the GHGs emitted from WWTPs, nitrous oxide (N2O) has beenidentifed as the potentially major component, due to its high global warmingpotential (GWP) which is 298 times higher than that of carbon dioxide (CO2)and also to its capability to react with stratospheric ozone, causing ozone layerdepletion. Up until now, most of the experimental investigations aimed at assessingthe key mechanisms of N2O formation and the operational conditions that canenhance its emission, have been carried out on conventional activated sludge (CAS)processes, while the knowledge of N2O emission from advanced technologiessuch as membrane bioreactors (MBRs) is still very limited. Moreover, the specifcpeculiarities of MBRs might hamper the direct transferability of data measured
