Resumen
Background: The present work explores the catalytic and electric performance of a microbial fuel cell (MFC) implementedwith high chemical oxygen demand (COD) industrial wastewater from Spain. The polymer inclusion membrane based on 70%[MTOA][Cl] IL was used as separator and showed a good efficiency in power production and COD removal .Results: Outputs of 72% in COD conversion, 200 mV voltage and 32 mW m−3power density were obtained, demonstrating thatslaughterhouse wastewater is a good feedstock for the scale-up of this technology. Furthermore, the effect of the microbialfuel cell on the physical/chemical parameters of the slaughterhouse wastewater was analyzed. The concentration of nitrite,orthophosphate, sulfate and ammonium was reduced by more than half. conclusions: Air breathing cathode-microbial fuel cells based on polymer ionic liquids inclusion membranes allow thetreatment of an industrial and high load slaughterhouse wastewater with good depuration and electrical performanceef ...
