A sustainable wastewater treatment technology should effectively reduce contaminant concentration, recovery energy contents and minimize liquid discharge. A potential candidate for such a technology is a microbial fuel cell (MFC) that can produce bioelectricity directly from wastewater treatment. However, the treated effluent from MFCs is not reused because of unsatisfied water quality. To produce high-quality water using MFCs, we proposed and studied two approaches with integrated membrane technologies. Especially, the osmotic MFCs that take advantage of both forward osmosis and MFCs have been proven feasible with bench-scale studies. The new function of producing high-quality water, although still very challengeable, will make MFCs a promising approach for sustainable wastewater treatment.
