Development of microbial fuel cell for wastewater treatment and electricity generation using domestic wastes

Background: The energy crisis is a growing problem around the world, requiring creation of alternative sources that can generate less carbon dioxide and benefit ecosystem. Reutilization wastewater becoming emerging solution. Wastewater contains large amount organic matter be oxidized in microbial fuel cells (MFCs) to produce electricity. MFCs use biodegradable materials create presence microorganisms. Methods: Purposive sampling technique was employed collect samples from critical polluting sources. were certainly maintained refrigerator at 4°C. Several mixes for sample prepared tested analytically- physio-chemical bacteriological characterizations each substrate status pre- post-treatment stages. Electricity generating capacity employing different substrates investigated experimentally using batch reactors. cross-sectional methodology study possible power generation. Results: maximum voltage output 118.93, 144.84, 89.76 mV produced keeping resistance unlimited MFC1 (urine substrate), MFC2 (blackwater MFC3 (graywater respectively. MFC utilized graywater as brought tiniest quantity electricity; however, it stood most stable. highest COD reduction (65.83%) process reported urine BOD5 removal (69.18%) black water substrate. Conclusion: experimental results provided promising indication viability, providing hope future generation treatment option developing countries.
