Claim 5:
6. A process of producing alkaline water containing sodium ions, carbonate ions, and bicarbonate ions having a pH of between 10.0 and 12.0, and acidic water having a pH of between 4.0 and 5.0 from an initial stream of water having a total dissolved solid content of between 0 ppm and 10 ppm, by electrolysis using an electrolysis machine having at least one cathode and at least one anode, and at least one filter of porous membrane having a particle size of no more than 1 μm, said process comprising the steps:
heating the initial stream to a predetermined temperature of at least 150° F.,
dissolving an alkaline salt of sodium propionate in the initial stream in a range from 26 ppm to 1321 ppm to produce a feed stream containing the cations of sodium and the anions of propionate and a residual of undissolved alkaline salt of sodium propionate,
removing the residual of undissolved alkaline salt from the feed stream by filtering the feed stream through at least one filter of porous membrane having a particle size of no more than 1 μm,
sterilizing the feed stream,
said step of sterilizing the feed steam being further defined as heating the feed stream to a boiling temperature of at least 212° F. for at least three minutes to sterilize the feed stream and eliminate bacteria,
sterilizing a cathode and an anode and an electrolysis machine,
said step of sterilizing the cathode and the anode and the electrolysis machine being further defined as washing the electrolysis machine and the cathode and the anode with an alkaline solution having a pH of at least 11.5,
directing the feed stream through the electrolysis machine at a predetermined flow rate of three liters per minute,
electrolyzing the feed stream to dissociate water into hydrogen ions and hydroxide ions and to produce the alkaline water adjacent to the cathode and acidic water adjacent to the anode,
said step of electrolyzing the feed stream further including a step of inserting the cathode and the anode into the feed stream in a spaced relationship,
said step of electrolyzing the feed stream further including a step of applying an electric potential between the cathode and the anode,
removing the alkaline water,
removing the acidic water,
isolating the alkaline water from ambient air and the acidic water to prevent the alkaline water from interacting with ambient air and the acidic water after said step of removing the alkaline water, and
isolating the acidic water from the ambient air and the alkaline water to prevent the acidic water from interacting with the ambient air and the alkaline water after said step of removing the acidic water,
and characterized by,
said step of applying the electrical potential being further defined as applying the electrical potential of between 20V and 50V between the cathode and the anode thereby migrating the hydrogen ions toward the anode to produce the acidic water having a pH between 4.0 and 5.0 and migrating the hydroxide ions toward the cathode to produce the alkaline water having a pH between 10.0 and 12.0 and dissociating the anions of propionate into hydrogen gas and carbon dioxide and ethylene and to react the carbon dioxide and the hydrogen gas and the hydroxide ions to produce carbonate ions and bicarbonate ions dissolved in the alkaline water containing sodium ions being present between 10 ppm and 150 ppm and the carbonate ions being present between 31 ppm and 440 ppm and the bicarbonate ions being present between 9 ppm and 70 ppm and zero hydroxide ions to define a total alkalinity between 40 ppm and 510 ppm and a total dissolved solids between 58 ppm and 1000 ppm, wherein the alkaline water has an Oxidation-Reduction Potential (ORP) of between −220 mV and −280 mV.
