Abstract

BACKGROUND: A circulating column microbial fuel cell (MFC) with Cu anode and Au-Cu air cathode was used for power generation and chemical oxygen demand (COD) removal from synthetic wastewater. The column was operated in repeated-fed batch mode using acclimated anaerobic sludge. The contents of the column MFC were circulated while the feed wastewater was fed to the reactor in fed-batch mode. Effects of feed COD concentration and COD loading rate on voltage difference, power density and percentage COD removal were investigated.
