Microbial Fuel Cell Technology in the Treatment of Industrial, and Municipal Wastewater

Wastewaters are the main source of many water pollutants in Iran and the world. Widespread environmental pollution is a danger that threatens future generations. Microfiber fuel cell (MFC) as a multi-purpose renewable energy technology can be used in the treatment of various wastewater and generation of electricity or bio-hydrogen, simultaneously. In this review paper, the performance of MFCs with the criteria of power generation, removal of toxic pollutants such as heavy metals and wastewater treatment efficiency with parameters such as chemical oxygen demand (COD) and coulombic efficiency (CE) are presented. According to the high diversity of wastewater that has been investigated over the past few years, the presented subjects in this paper has been divided into several groups of synthetic, food and food-processing, industrial, municipal wastewaters.
