Evaluating the Influence of Substrate Types and Concentrations on Power Generation in Microbial Fuel Cells
Microbial fuel cells (MFCs) offer a sustainable solution for simultaneous wastewater treatment and electricity generation. This study investigates the impact of different substrate types glucose (1 g/L, 3 g/L, 5 g/L), sago wastewater, and landfill leachate on MFC performance. A dual-chamber MFC sy...

| Summary: | Microbial fuel cells (MFCs) offer a sustainable solution for simultaneous wastewater treatment and electricity
generation. This study investigates the impact of different substrate types glucose (1 g/L, 3 g/L, 5 g/L), sago
wastewater, and landfill leachate on MFC performance. A dual-chamber MFC system with stainless steel electrodes
and salt bridge was used over a 5-day batch operation. Voltage output and Chemical Oxygen Demand (COD) removal
efficiency were recorded. The highest COD removal (56%) was achieved with 1 g/L glucose, while the highest voltage
output (392 mV) came from 3 g/L glucose. Landfill leachate also performed well, showing 50% COD removal and
382 mV peak voltage. Sago wastewater showed moderate performance. These results underscore the importance of
substrate selection and concentration in optimizing MFC systems for renewable energy and wastewater treatment. |
