    The purpose of this study was to clarify the temperature effect of continuously expanding anaerobic digester(CED) for raw dairy slurry at temperatures of 15, 20, 35 and 42.5 C using bench size digesters.
    The results were summarized as follows :
1. There were no significant differences between 20, 35 and 42.5 C in the methane concentration.
2. Methane yield at 35 C digester was higher than other temperature (15, 20 and 42..oC) digesters.

Keywords: continuously expanding anaerobic digestion, temperature dependency, dairy manure slurry, methane digestion.
