Development of microbial fuel cells (MFC) for wastewater treatment

Current wastewater treatment technology has some problem concerning the environmental load. For example, the activated sludge process of aerobic wastewater treatment requires the large consumption of electricity and the high excess sludge disposal cost. The methane fermentation process of anaerobic … Continue reading
