ABSTRACT:
An electro-chemical system for liquid filtration for effecting removal of dissolved and suspended solids, undesirable ions, etc, therefrom, and decontaminating same, involving a basic electro-chemical filter device that comprises 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 filrant and being closed off at its lower end. The canister adjacent its lower end is equipped with a cross tube extending therethrough and across the canister bore and having a width that is on the order of seventy-five percent of 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, of which the sheeting is a pair of foraminous electrically conductive sheets separated by a sheet of fibrous material defining pore spaces approximating one-five microns in size. 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 sheets separated by one or more layers of fibrous material defining porous space openings on the order of fifteen-twenty-five microns in size. The foraminous sheets in the two filter units involved are charged anode-cathode fashion by electrical connection to a 12 volt 50 amp D.C power source for polarizing the filter units, continuous recirculating passing of filtrant through the filtration system at a normal 50 psi pressure provides a pure filtrate outflow on the order of 150 gallons per minute with solid size removal efficiency in the range of down to 0.5-5 microns
