Anode material is one of the most important factors on the application of microbial fuel cells for wastewater treatment due to its key role in forming exoelectrogenic biofilm and transferring electrons along with the high investment cost. In this study, carbon brush (CB), carbon cloth (CC) and graphite felt (GF) were investigated as alternative anode materials for 6 L single-chamber dual air-cathode microbial fuel cells (MFCs) in terms of starting-up rate and electricity production with artificial wastewater and slaughter wastewater. The cost effectiveness of anode materials was also evaluated.
