Further Investigation of the Power Generation and Pollution Removal Capacity of Microbial Fuel Cells for the Treatment of High Nickel Content Wastewater

This study investigates microbial fuel cells (MFCs) for the treatment of high nickel-contaminated wastewater and their ability to generate electricity at different nickel levels. As well as exploring trends in treatment capacity, optimal conditions for achieving functionality were identified and the effects of time and nickel dose were assessed. Nickel is commonly found in industrial wastewater, and this study measured removal efficiency by comparing influent and effluent concentrations. The results indicate that increasing nickel levels reduce the power generation capacity of the MFC, which may affect long-term efficiency. However, the ability of MFC to remove COD and nickel was unaffected by increasing nickel levels, highlighting the potential of MFC to treat industrial wastewater without increasing resources.
