Synthetic waste water contain organic compound can be oxidized in an anaerobic conditions in microbial fuel cell while biodegradation of Chemical Oxygen Demand (COD) takes place under anaerobic condition in anode compartment. The microorganisms for biological treatment of the organic matter were obtained from a UASFB bioreactor. In the treatment of waste water, ones COD was removed the current and power was generated and record. Also polarization curve was obtained. In cathode compartment ferocynide and potassium permanganate with several concentration were add for enhancement of proton oxidation. The performance of MFC for maximum current and power generation were obtained with 300 µM L-1 potassium permanganate as oxidizers agent. Maximum generated power and current densities were 22 mW/m2 and 70 mA/m2, respectively. Active microorganisms used acetone as electron donors and COD removal was 69% at the end of process.
