Abstract

Remediation of textile industrial waste water using a Microbial Fuel Cell (MFC) with 0.4% sodium acetate as substrate is described. In this study, waste water samples from textile industry have been used with varying optical densities of Enterobacter cloacae to assess the bio-remediation efficiency and electrical potential. Textile waste water was found to generate voltage of 502.1 mV which increased to 801.33 mV when pellet of 100 mL Enterobacter cloacae culture was mixed with textile waste water in anodic chamber. Coulombic efficiency of textile waste water alone was 57%, which increased to 80.1% with textile waste water containing 100 mL Enterobacter cloacae pellet. The present study clearly demonstrated that remediation of waste water using MFC technology can be greatly improved by the addition of Enterobacter cloacae as revealed by a decrease in COD value
