Perumbavoor is a densely populated and industrialized urban area, resulting in heavily polluted effluent, making the wastewater treatment a critical issue. This project aims to discover a better alternative, a microbial fuel cell (MFC) plant, which not only cleans the waste water but also produces electricity. The MFC generates electricity through microbial activity, in which bacteria break down the organic matter in the waste water. This innovative approach treats the restaurant waste water which is rich in organic pollutants, by using MFCs to convert chemical energy into electrical energy and clean the wastewater. The plant design includes multiple MFCs arranged in series-parallel to optimize power output and treat large volumes of wastewater.
