COD reduction and power generation from dual-chamber microbial fuel cells fed with sheep manure wastewater

Abstract

One of the significant sources of organic materials is livestock manure wastewater. In this study, the current density from livestock wastewater (sheep manure) was examined in a microbial fuel cell. Dry manure samples were added to clean water to form wastewater of manure liquid ratio. Four ratios of solid to liquid were used: 25, 50, 75 and 100 g/l. Per findings COD reduction efficiencies were up to 95%, 91%, 89% and 86% for MFC loaded with 25, 50, 75 and 100 g/L sheep manure wastewater and for a hydraulic retention time of 15 h. Per findings sheep manure can be a reusable feedstock for electricity production as the current density at the rate of 1608, 1166, 875 and 700 mA/m² for an MFC loaded with 100, 75, 50 and 25 g/L sheep manure wastewater for the same hydraulic retention time.
