Bioenergy recovery associated with treatment of actual meat industry wastewater in blue green algal biocathode based microbial fuel cell: Experimental and modeling study

Abstract

The photosynthetic microbial fuel cell (PMFC) being one of the microbial fuel cells (MFCs) type, seems to be as a great promising technology for wastewater treatment accompanied with renewable energy production. This study aimed to evaluate the performance of blue-green algae-based PMFC for simultaneous biotreatment of actual slaughterhouse wastewater (SWW), ammonium removal, and bioenergy recovery. The experimental results demonstrated significant removal efficiency of chemical oxygen demand (COD) and ammonium (NH4+) of 99.6 ± 0.5%, and 82.7 ± 1.5%, respectively associated with a power output of 469.6 ± 3.0 mW/m². Butler–Volmer–Monod model was applied to describe the overpotential-polarization curve for the suggested PMFC. A significant agreement was observed between the experimental and predicted results with a determination coefficient (R2) value of 0.974. The observed favorable results reported in this investigation strongly encourage the use of the proposed technique for the treatment of slaughterhouse effluents.
