Sewer gas emission (i.e. H2S and CH4) aggravates sewer pipe corrosion and global warming. Current sewer gas control strategies rely on chemical dosing, which has a limited and transient effect. This research proposes Bioelectrochemical system (BES) as an alternative sewer gas control technology, which can in theory reduce chemical doses and achieve a long-term operation with minimal maintenance. We will first demonstrate the proof-of-principle of BES sewer gas control and study the influence of environmental conditions (e.g. temperature, hydraulics, etc.) on its performance. Subsequently we will investigate the long-term efficiency and stability of BES sewer gas control in real-life conditions.
We provide a disciplinary and multidisciplinary research programme aimed at advanced understanding of environmental problems and advanced training of PhD candidates in this field.
