This study was conducted to develop a new feeding wastewater system that alkali supply is reduced in methane fermentation processes treating two types of acidic wastewater, i.e. sweet potato-based alcohol distillery wastewater and bio-ethanol distillery wastewater. The system could supply wastewater in the height direction, and was successful to reduce alkalinity to 63% and 36% in mesophilic and thremophilic methane fermentation processes, respectively, at the COD loading rate of 30 kgCOD/m3/day.
