Comparative Analysis of Voltage Output and Physico-Chemical Effects of Four Membranes in Microbial Fuel Cells Using Domestic Wastewater

Currently, the vision of the manufacturing industry intends to supply its production with efficient energy resources whose purpose is to replace conventional energy production technologies, which cause environmental imbalance by generating high amounts of pollution, for which microbial fuel cells They are a viable alternative where energy is generated from the removal of the organic load from domestic or industrial wastewater. In this study, the efficiency of the proton exchange membrane was evaluated in relation to the production of potential difference and removal of organic matter, for which four cells were assembled on a laboratory scale with different membranes under the same conditions and components. Regarding the potential difference efficiency, it was decided to collect and analyze the data for three months every 25 min, resulting in the Nafion 117 membrane being the one with the best efficiency with an average of 98.61568 mV, in terms of organic load removal the Parafilm membrane was the most efficient option with a percentage of 20.16% BOD & 35.27% COD, however, the most viable option for the design of a microbial fuel cell was Parafilm as the most complete membrane in terms of the production of potential difference and decontamination of domestic wastewater.
