title: Enhanced methane production from pig slurry with pulsed electric field pre-treatment.
abstract: Intensive amount of manure produced in pig breeding sectors represents negative impact on the environment and requires optimal management. Anaerobic digestion as a well-known manure management process was optimized in this experimental study by pulsed electric field (PEF) pre-treatment. The effect of PEF on methane production was investigated at three different intensities (15, 30 and 50 kWh/m3). The results indicate that the methane production and chemical oxygen demand (COD) removal was improved by continuous escalation of applied intensity, up to 50 kWh/m3. In comparison with untreated slurry, methane production and COD removal were increased up to 58% and 44%, respectively.
