Abstract:
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.
