Abstract: Microbial fuel cells (MFCs) set a new trend of converting chemical energy or bio energy to electricity from wastewater (domestic and industries) at the same time removal of chemical oxygen demand (COD) from the wastewater. Electrical energy generated from microbial fuel cell could be used for small electrical device example biosensors. The main components of MFCs are the anode, and the cathode salt bridge. It contains an anode chamber and a cathode chamber which separate electrodes for the production of electricity, using wastewater in an anaerobic chamber helps grow native microorganisms. Adding substrates increases productivity of the electrons that are moving from the anode chamber to the cathode chamber by help of the salt bridge. Bioreactors based on power generation in MFCs are a new approach to wastewater treatment. Power generation and current is modulated in this system. If it is optimised, MFCs would prove to be new method to offset wastewater treatment plant operating costs.
