ELECTRO-CHEMICAL SYSTEM FOR LIQUID FILTRATION Abstract of the Disclosure An electro-chemical system for liquid filtration involving a basic electro-chemical filter device that com- prises a canister of cylindrical form that in mounted position is vertically disposed and that defines a bore extending longitudinally of same, with the canister at its upper end being connectable to the source of liquid filtrant and being closed off at its lower end. The canister adjacent its lower end is equipped with a first filter unit comprising a cross tube extending therethrough and across the canister bore and having a width that is less than the width of the canister bore, with the cross tube having a tubular mandrel disposed in same and extending substantially coextensively thereof, and with the portions of the cross tube and mandrel disposed within the canister each being formed to define multiple liquid passing apertures thereabout. Convoluted about the mandrel and in tight fitting relation between the mandrel and cross tube is an elongate composite filter sheeting in the form of a pair of foraminous electrically conductive and charged sheets separated by a sheet of fibrous material defining relatively small pore openings. Disposed in the canister bore between its upper end and the cross tube is a second coarser filter unit of composite disc form disposed crosswise of the canister bore and comprising a pair of foraminous electrically conductive and charged sheets separated by one or more layers of fibrous material defining larger porous space openings than those of the first filter unit.
