Abstract

Microbial Fuel Cells (MFCs) offers a promising solution for addressing both waste water treatment and challenges in renewable energy production. This study aims to explore the integration of MFCs with adsorption/bio-oxidation (AB) process to tackle wastewater management difficulties while generating renewable energy. By investigating microbial mechanisms within MFCs, enhancing pollutant removal efficacy, and assessing MFC application feasibility, we seek to advance eco-friendly wastewater treatment and renewable energy harvesting. Lab-scale experiments will identify microbial communities, characterize electron transfer processes, and evaluate MFC performance in pollutant removal. Through systematic experimentation with varied operational parameters and substrate concentrations, we aim to optimize MFC efficiency. Electrochemical assessments, including power output tests and electron flow rates, quantify MFC energy generation capabilities. Environmental and financial sustainability aspects, such as cost-benefit analysis and life cycle assessment, will be integrated to assess MFC viability compared to traditional wastewater treatment systems. The outcomes of this research will contribute to scientific knowledge expansion, providing insights for policymakers, water utilities, and environmentalists to embrace green technologies for water contamination mitigation, energy efficiency enhancement, and sustainable development.
