GREEN APPROACH FOR THE TREATMENT OF TEXTILE WASTEWATER USING MICROBIAL FUEL CELL AND BIOELECTRICITY PRODUCTION

Abstract

Microbial fuel cell (MFC) is a green and promising alternative for saving the depleting nonrenewableresources. In the present research, MFC technology is utilized to bring aboutdetoxification of textile wastewater with simultaneous production of electricity. Textile wastewaterhas a high pH value, high concentrations of dyes, organic pollutants, suspended solids, chlorides,nitrates, heavy metals (high BOD and COD values). The high organic load in the wastewatermakes it function as the useful substrate for microorganisms in MFC. Experimental results showedthat MFC using textile wastewater gave excellent electrical output of 546 mV after 60 h of operationIt has been found under the operating conditions of the experiments, there was 90–95% reductionin colour, TDS, BOD and COD of the textile wastewater.
