Abstract: The waste sewage that accumulates from humans, animals and vegetables is first diluted with water to provide a product comprising twenty parts water to one part solids by weight. This diluted product is subjected to a macerating and comminuting and mixing operation that breaks down the lumps in the solids to a size where they are either dissolved or carried in suspension. From the macerator, the fluid is moved up through a screen chamber having a screen of 1/8 inch to remove any heavy, large particles therein and is next pumped into non-conductive electrolytic cell containers. An overflow connection returns any gas and excess liquid into the screening chamber.
