WebThe results indicated that CD and PGD inoculum were more suitable for the anaerobic digestion of FW than other livestock dungs. Reactors inoculated with CD achieved higher methane production (227mLg1VS degraded) and volatile solids degradation (54.58%) at F/M ratio maintained at 2. 展开 Webvolatile acids to alkalinity ratio at 0.25 or less is desirable for good operations. Temperature control is important for methane forming bacteria. They function in the range of 85 degrees - 100 degrees F. which is known as the mesophilic range. Another temperature range is 120 degrees - 135 degrees F. and is known as the thermophilic range.
