sludge disintegration with stirred ball mills
Comparison of Disintegration Methods at a Fullscale ...
of and behind the disintegration aggregate. Methods of Sludge Disintegration Stirred Ball Mills consists of a cylindrical grinding chamber which is almost completely filled with grinding beads. A rotor forces the beads into a rotational movement. The microorganisms are disintegrated between the beads by shear and pressure forces.

Dewatering of disintegrated surplus sewage sludge
The disintegration methods investigated in this research work have all been proven to be suitable for breaking up microorganisms. For continuous operation stirred ball mills and highpressure homogenizers are applied. The impact of disintegration on sewage sludge characteristics and dewaterability have been examined.
