Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 6,   Pages 1108-1116 doi: 10.1007/s11783-015-0806-x

Abstract: High-solids anaerobic digestion of sewage sludge was a promising process, but high solid concentrationThe results showed that TS 6% was the boundary between low-solids and high-solids anaerobic digestionThe performance of anaerobic digestion was directly determined by the efficiency of mass transfer, anddigestion.Consequently, the deterioration of high-solids anaerobic digestion was related to the blocked mass transfer
