Patent ID: 7691249

Claim:
A method of making an electrolyzed liquid comprising: providing an electrolysis cell comprising an outer tubular electrode separated from an inner tubular electrode by a tubular ion permeable membrane arranged coaxially one within the other and a pair of end caps where the space between the inner tubular electrode and the membrane and the space between the membrane and the outer tubular electrode defines anode and cathode compartments where one of the electrodes functions as an anode and the other electrode functions as a cathode; providing a liquid comprising water or brine to the electrolysis cell and while in the electrolysis cell is contained within the anode and cathode compartments and the end caps; and applying a current across the electrodes, wherein each end cap provides a sealing engagement between the end cap and each of the inner tubular electrode, the outer tubular electrode, and the membrane, wherein the end cap 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 cap, and wherein the end cap comprises: a first annular section of insulating material with first and second axial ends, having at its first axial end a circular seating for one end of the outer cylindrical electrode and at its second end a circular aperture, of smaller diameter than the circular seating and coaxial therewith, to accommodate one end of the cylindrical membrane, and a second annular section of insulating material detachably secured to the first annular section and having a central circular aperture, of smaller diameter than the central aperture of the first annular section and coaxial therewith to accommodate one end of the inner cylindrical electrode.
