In situ investigation of tubular microbial fuel cells deployed in an aeration tank at a municipal wastewater treatment plant

- Three MFCs were installed in an actual aeration tank for more than 400 days.
- Those MFCs were able to produce electricity while reduce organic concentration.
- The performance was affected by cathode biofouling and operating conditions.
- MFC may not be suitable for deployment in aeration tanks unless further improvement.
