The Effect of Temperature on Continuously Expanding Anaerobic Digestion (II)

A Characteristics of Dairy Slurry for CED

Abstract

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 42.5°C) digesters.
