Abstract
This work examines the methane production potential for the anaerobic co-digestion of swine manure (SM) with winery wastewater (WW). Batch and semi-continuous experiments were carried out under mesophilic conditions. Batch experiments revealed that the highest specific methane yield was 348Â mL CH4Â gâ1 COD added, obtained at 85.4% of WW and 0.7Â g CODÂ gâ1Â VS. Specific methane yield from SM alone was 27Â mL CH4Â gâ1 COD added dâ1. Furthermore, specific methane yields were 49, 87 and 107Â mL CH4Â gâ1 COD added dâ1 for the reactors co-digesting mixtures with 10% WW, 25% WW and 40% WW, respectively. Co-digestion with 40% WW improved the removal efficiencies up to 52% (TCOD), 132% (SCOD) and 61% (VSS) compared to SM alone. These results suggest that methane can be produced very efficiently by the co-digestion of swine manure with winery wastewater.
