| Research Abstract |
Microbial fuel cells (MFCs) were studied for simultaneous wastewater treatment and biological electricity generation by direct conversion of chemical energy in organic compounds into electricity. Electricity generation from artificial wastewater was examined using two-chamber MFCs and air-cathode single-chamber MFCs. Anaerobic sludge and activated sludge were used as biocatalysts. The air-cathode single-chamber MFCs showed higher power densities. It was suggested that electrochemically active bacteria in activated sludge differed from those in anaerobic sludge. For realization of the MFC systems, improvement of the reactors and information on the MFC bacteria will be further needed.
