Abstract

Biodegradable materials are used in microbial fuel cells to produce energy when microbes are present. Large amounts of organic material found in wastewater can be oxidized in MFCs to provide power. In the current situation energy crisis is a growing problem throughout the world, which necessitates the creation of alternative energy sources that generate less carbon dioxide and benefit the ecosystem, like the use of wastewater best solution for such challenge. The goals of the study were examined through laboratory-based experimentation. The capacity of microbial fuel cells and the type of substrate employed were evaluated using experimental research designs. Experimental methods were used to determine the amount of electric current generated by wastewater during treatment. Maximum Voltage Output or OCV (open circuit voltage) values of 118.93 mV, 144.84 mV, and 89.76 mV are attained for MFC1, MFC2, and MFC3, respectively, when the resistance is infinite. The MFC that employed graywater as a substrate produced the least amount of electricity of the three, but it was the most stable. COD reduction was highest in urine waste, at roughly 65.83%, compared to 56.69% and 58% for blackwater and graywater waste, respectively and BOD₅ removal of substrate urine, blackwater and graywater are 67.79%, 69.18% and 28.89% respectively value. MFC 2 had the highest maximum power output, with a value of 0.00655 W/cm² equating to 0.00453A/cm² of current. It found the following values for the other fuel cells: 0.00442 W/cm², and 0.00251 W/cm², corresponding to current values of 0.00372 A/cm², and 0.00281 A/cm²are respectively value of MFC1 and MFC3 are respectively value.
