Abstract
Recirculation is one of the effective techniques used to upsurge the output of anaerobic reactors. The present study investigates the effect of recirculation of anolyte on bioelectricity generation using food waste leachate in two chamber Microbial Fuel Cell (MFC) with carbon electrodes and Ultrex as proton exchange membrane (PEM). The MFCs are operated in fed-batch mode at varying COD concentrations of 500-1250Â mg/L with the hydraulic retention time of 17Â h for recirculation. Maximum current density, power density and columbic efficiencies of 100.34Â mA/m2, 14.42Â mW/m2 and 10.25% respectively for MFC without recirculation and 150.30Â mA/m2, 29.23Â mW/m2 and 14.22% respectively for MFC provided with recirculation are obtained at COD of 1250Â mg/L. Comparative performance analysis of the cells indicates that recirculation enhances the bioelectricity production in MFC. Scanning Electron Microscope (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) analyses are also done to find the changes in PEM.
