Abstract The effects of charge size, cycle time, and the presence of added N on the extent of solubilization and biodegradation of microbial solids were investigated during semi-continuous operation of an aerobic thermophilic digestion process. Use of a charge size of 50% of the bioreactor operating volume resulted in the removal of more than 59% of the total suspended solids concentration in the feed and showed enhanced performance compared with when a 25% charge size was used. The addition of a supplementary N source resulted in enhanced dissolved organic carbon (DOC) concentrations with the 50% charge size, but did not affect overall solids removal. With the 25% charge size, addition of a supplementary N source resulted in an overall improvement in process performance.
