Abstract

The growing need for sustainable energy solutions and efficient wastewater treatment methods is bringing microbial fuel cells (MFCs) into the spotlight. One of the unique renewable energy options that effectively treats wastewater while simultaneously generating power is microbial fuel cells (MFCs). This research explores the potential of using MFCs to produce electricity from dairy wastewater, which is characterized by a high organic content. With its significant amounts of lactose, lipids, and proteins, dairy effluent serves as an excellent substrate for microbial activity. The MFC setup was constructed with two compartments utilizing graphite electrodes and a proton exchange membrane. The evaluation of performance was centered on voltage generation and power density. The microbial fuel cell (MFC), an essential category of bio-electrochemical systems, utilizes the activity of microorganisms.
