Efficient decolorization of real dye wastewater and bioelectricity generation using a novel single chamber biocathode-microbial fuel cell

▸ A highly scaled-up MFC for decolorization of real dye wastewater and electricity generation. ▸ We have addressed most of the obstacles that hinder large scale applications of MFC. ▸ The proposed MFC produced a high power density with high removals of color, toxicity and COD. ▸ GAC-biocathode can be an excellent alternative to Pt and other chemical catalysts.
