Background/Objectives: Swine slurry is generally used as raw liquid fertilizer and leads environmental pollution. Therefore to overcome that, anaerobic digestion before its field application would reduce pollution and give bioenergy. Methods/Statistical Analysis: The dynamics of biochemical parameters in swine slurry are not fully evaluated in anaerobic system. In this study, basic changes in physico-biochemical character (pH, EC, solids, organic matters, nutrients, heavy metals, pathogens and methanogens) of swine slurry under mesophilic anaerobic digestion using batch system is evaluated. Findings: During mesophilic anaerobic digestion of swine slurry was shown the removal rate of organic matters at 85% and 75% in terms of BOD5 and SCODCr. The pathogens of Salmonella and fecal coliforms removed at 100% and 97%. Interestingly, the nutrients contents were increased at 19% and 12% in terms of NH3-N and available phosphorous, respectively. The biochemical methane potentials of swine slurry was observed at 236 L/kg CODadded, and 307 L/kg VSadded, respectively. The methane accounted for 54.3% of the biogas produced with the dominant population of Methanosarcina sp. Conclusion/Improvements: It is concluded that the mesophilic anaerobic digester is greatly desirable for swine slurry with regards of bioenergy, ecofriently liquid biofertilizer production and significant biodegradability of organic waste.
