The anaerobic sludge stabilisation (digestion) is the most common method for sludge treatment in Europe and Germany. Using non-mechanical (chemical, biological and physical) or mechanical disintegration the degradation of sludge can be improved. Beside the common sludge disintegration methods, the technology of electrical shock waves produced by pulsed power system seems to be an economical alternative.
Beside the technical concept of the pulsed power system and the general operation parameters, large and small scale sludge disintegration experiments will be presented. The influence of specific energy input on the degradability of disintegrated sewage sludge in anaerobic digestion systems can be seen.
The results of the disintegration experiments will be compared to the results of the common disintegration methods, and the up-scaling relations for a full scale electrical shock wave disintegration system will be deducted.
