The discharge of emerging contaminants (ECs) into the environment has raised great concerns due to their negative effects on the ecosystem. Intensive research efforts have been undertaken in order to find effective methods to treat these compounds. In this study, the removal of four ECs including Bisphenol A (BPA), Estrone (E1), Sulfamethazine (SM2), Triclocarban (TCC) was investigated in the microbial fuel cell (MFC)-Fenton system. Glucose and graphite rod with stacked graphite granules were used as the substrate and electrode, respectively since they improved current density of MFCs system and increased cathodic H2O2 synthesis. Both batch and continuous flow modes of MFCs were compared and the operational parameters for higher H2O2 yield were also studied. The results showed that for both batch and continuous flow modes, initially the H2O2 production had a rising trend and arrived at the highest level but subsequently it decreased. We later
