Textile dye decolorization & bioelectricity generation in a microbial fuel cell

Abstract

Microbial fuel cells (MFC) have been gained a considerable attention during past few decades due to its ability to treat wastewater effluents while generating bioelectricity. In this study anode to cathode area ratio was varied to maximize the output voltage simultaneously achieving the required color reduction. The highest voltage was observed as 515mV from anode to cathode area ratio of 3:1 on the 7th day from the beginning. At the latter stage, all arrangements show more than 85% color reduction at 200h. Therefore, it can be concluded that electrode area ratio has no significant effect for the fractional color reduction.
