Method of treating waste-activated sludge using electroporation

In parent application Ser. No. 09/468,427, there is disclosed a system and method for dewatering and treating waste-activated sludge (WAS) emanating from municipal waste, or pulp-waste from a paper mill, as well as treating animal and plant waste. In that application, the method for breaking down the WAS is to subject the WAS to electroporation, which incorporates nonarcing, cyclical high voltages in the range of between 15 KV and 100 KV, which break down inter-cellular and intracellular molecular bonds, to thus release inter-cellular and intracellular water, whereby the WAS is rendered inactive and greatly reduced in mass. 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 dewatering treatment, direct WAS-treatment, and combinations with other conventional dewatering techniques, in order to provide the municipal treatment plant, or the paper-pulp treatment plant, with 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 electroporation process causes the release of intracellular dissolved/organic matter, which is used as "food" for the bacteria of the aeration tanks.
