The Overall Performance Improvement of Microbial Fuel Cells Connected in Series with Dairy Wastewater Treatment

To improve the potential of single chamber microbial fuel cells (SCMFCs) as an applicable technology, main challenge is a practical application for larger scales bioenergy production from potent exoelectrogenic microorganism with real dairy wastewater. increase power generation, three individual MFCs were together operated in series best under fed batch condition 15 days. The volume MFC 1 and 2 “ 300 mL” 3 “500 respectively. 1, gives open circuit voltage 0.60 V, 0.66 V 0.55 result total working when connected 1.745V, which lead LED to glow. maximum densities obtained are 62 mW/m2, 50 mW/m2 45 (normalized surface area anodic electrode, was cm2 all MFCs), corresponding current 141 mA/m2, 155 mA/m2 123 Therefore this work suggests cheapest way connect gain lowest operating cost chemical oxygen demand (COD) removal.
