An optimum of the bead diameter and the stress intensity in stirred ball mills could be detected. A comparison of the results of different methods of sludge disintegration shows that the investigated ultrasonic homogenizers are inferior to a high pressure homogenizer and a stirred ball mill in terms of energy consumption.

The stirred ball mill (SBM) method is a common method applied in large-scale sludge disintegration. Many reports focus on the disintegration results of sludge or the influence of parameters on the anaerobic process of treated sludge, but there have been few studies on the mechanism of sludge disintegration by SBM.
