ELECTRICITY PRODUCTION FROM WASTE WATER BY MICROBIAL FUEL CELL

A microbial fuel cell (MFC) is a bio-electrochemical system that converts the chemical energy in the organic compounds such as acetate, lactate, and glucose. It converts renewable energy sources to electrical energy under anaerobic conditions. So it is possible to produce electricity in a MFC from wastewaters. This process is an alternative methodology for generation of electricity. Here the MFC used three different wastewater samples which were achieved maximum power with Tannery effluent was obtained  414 mV followed by municipal wastewater 254 mV and  domestic waste water  244 mV. It has been found that a mixture of cow dung can actually result in higher voltage than lechate and kitchen waste. MFC also used to treat the wastewaters under anaerobic process. The highest efficiency of DO removal has been achieved by Tannery waste water (57.14 %), followed by municipal wastewater (50 %) and pond water (44.4%). The Tannery effluent shows the highest efficiency for TSS ( 55.4 %), followed by  municipal waste water (51.64 %) and pond water (46.98 %).
