Dual Diaphragm Electrolysis cell assembly and method for generating a cleaning solution without any salt residues and simultaneously generating a sanitizing solution having a predetermined level of available free chlorine and PH

A method of making electrolyzed liquids utilizing an electrolysis cell comprising an outer cylindrical electrode separated from an inner cylindrical electrode by at least one cylindrical cation ion-exchange membrane and at least one anion ion-exchange membrane arranged coaxially one within the other to create a cathode chamber, an electrolyte chamber and an anode chamber wherein the outer cylindrical electrode is of greater diameter than the anion ion-exchange membrane proximal to the outer cylindrical electrode which is of a diameter greater than the cation ion-exchange membrane to the outer cylindrical electrode and the diameter of said cation ion-exchange membrane is greater than the inner cylindrical electrode;

• providing a pair of end pieces where the space between the inner tubular electrode and the cation ion-exchange membrane and the space between the anion ion-exchange membrane and the outer tubular electrode defines anode and cathode chambers;
• where the space between the anion or cation ion-exchange membrane defines the electrolyte chamber and where one of the electrodes functions as an anode and the other electrode functions as a cathode;
• providing a saturated brine solution to the electrolyte chamber of the electrolysis cell and providing softened water to the anode and cathode chamber applying a current across the electrodes, wherein each end piece provides a sealing engagement between four sections of the end piece and each of the cylindrical electrodes and the anion ion-exchange membrane and the cation ion-exchange membrane, wherein the end piece has a lateral inlet through an outer wall thereof, said inlet being provided with a fitting for tangential feeding of the liquid to the inside of the end piece, and wherein three pairs of ports for entrance or exit of fluid are situated in an upper and a lower end piece, each comprising an external fitting for attachment of a hose or pipe, wherein said first pair of ports at opposite ends of said assembly internally addresses a space between said outer electrode tube and said anion ion-exchange membrane and said second pair of ports at opposite ends of said assembly internally addresses a space between
• said·cation ion-exchange membrane and said anion ion-exchange membrane and said third pair of ports at opposite ends of said assembly internally addresses a space between said inner electrode tube and said cation ion-exchange membrane.
