The purpose of this study was to investigate the potential of methane production from anaerobic co-digestion of coco husk with digested swine manure. The experiment was set up in the batch system. Inoculum utilized in this experiment was derived from semi-continuous reactor run at steady state condition, with 25 days of hydraulic retention time and mesophilic condition. The temperature applied in this experiment was maintained under mesophilic condition, which was 35oC. The highest methane productivity generated from anaerobic co-digestion of cocoa husks (CH) with digested swine manure was 345.8 ± 7.82 mL/day, which was higher compared with the anaerobic digestion of digested swine manure alone (286.97 ± 16.8 mL/day). CH reactors had less methane... |
