Abstract :
The need for alternate eco-friendly fuel is growing rapidly with depletion of non-renewable energy resources. Also it has ignited extensive research in identifying a potential, cheap and renewable source for energy production. Besides the building of a sustainable society will require reduction of dependency on fossil fuels and lowering of the amount of pollution that is generated. Waste treatment is an area in which these two goals can be addressed simultaneously. As a result, there has been a paradigm shift recently, from disposing of waste to using it. Microbial fuel cells (MFCs) represent a new form of renewable energy by converting organic matter into electricity with the help of microorganisms already present as catalyst, while simultaneously treating the wastes. This study was designed with the purpose of evaluation the simultaneous electricity production and wastewater bioremediation by microorganisms in a microbial fuel cell based on salt bridge. Results showed that the maximum voltage produced was 1 V on the earlier day of MFC operation. After that the voltage was lowed slowly and the wastewater sample was also treated partly. Also the MFC produced a maximum current of 256μa on day 2. Hence we can describe twofold and successful role of this reactor in electricity generation and wastewater bio-filtration.
