Beschreibung
Zusammenfassung:	A system that allows the flexibility of primary and secondary treatment of municipal sludge, paper-pulp sludge, animal and plant waste, whereby the treatment thereof via electroporation may be used either as the primary dewatering treatment, secondary dewartering treatment, direct WAS-treatment, and combinations with other conventional dewatering techniques, in order to provide the municipal treatment platn, or the paper-pulp treatment plant, wi th the most cost-effective and efficient system as possible. The electroporated - treated sludge releases hitherto unreleased biosolids exiting from the PEF- electroporation system, which are returned to aeration tanks. The elelctroporation process causes the release of intracellular dissolved/organ ic matter, which is used as "food" for the bacteria of the aeration tanks.
