Abstract:

The hydrolysis of particular organic solids, which is often the rate-limiting step of anaerobic digestion, can be supported by comminution of the material, creating new surfaces and releasing cell compounds in the suspension. An accelerated digestion of all solids and an extended degradation of substrates with a high fibre content could be observed.

 

Keywords:
