microbial fuel cell wastewater treatment

07 Jan microbial fuel cell wastewater treatment

Current wastewater treatment technologies are not sustainable simply due to their high operational costs and process inefficiency. Extensive studies on MFC have focused on structural design and performance optimization, and tremendous advances have been made in these fields. Integrated Microbial Fuel Cells for Wastewater Treatment is intended for professionals who are searching for an innovative method to improve the efficiencies of wastewater treatment processes by exploiting the potential of Microbial Fuel Cells (MFCs) technology. Microbial fuel cell technology was examined in treating agricultural wastewater with nitrogenous and organic compounds. endobj 16 0 obj stream Exoelectrogens are more than happy to breakdown and metabolize the carbon rich sewage of a waste water stream to produce electrons that can stream into a cheap conductive carbon cloth anode. 4 0 obj Most such SMFCs contain plants to mimic constructed wetlands.
