Method for concentrating ions in a solution

A method for forming a concentrated solution of ions in a solvent, said solvent having a freezing temperature when said solvent is pure, said method comprising the steps:

• (i) mixing one constituent in said solvent,
• (ii) mixing another constituent in said solvent in an amount equal to a mole equivalent of said one constituent wherein said one constituent and said another constituent are selected to result in formation of a precipitate of said one constituent compounded with said another constituent and result in formation of said ion in said solvent;
• (iii) removing said precipitate from said solution leaving said solution containing said ions in said solution;
• (iv) reducing the temperature of said solution to a temperature range that is below said freezing temperature and where one portion of said solution is frozen and has a greater concentration of said ions in said solvent and another portion of said solution is liquid and has a lesser concentration of said ions in said solvent;
• (v) separating said one portion that is frozen from said another portion which is liquid.

A method for forming a concentrated aqueous solution of hydronium ions comprising the steps:

• (i) placing said water in an a container including an ion membrane filter between a cathode in a cathode chamber and an anode in an anode chamber;
• (ii) passing electrical current between said cathode and said anode whereby hydronium enriched aqueous solution is generated in said anode chamber.
• (iii) reducing the temperature of said hydronium enriched aqueous solution to a temperature selected from the range between 25° F. and 28° F. and where one portion of said aqueous solution is liquid and has a greater concentration of hydronium ions and another portion is solid and has a lesser concentration of said ions in said solvent;
• (iv) separating said one portion which is liquid and hydronium ion enriched from said another portion which is frozen.

An apparatus for increasing concentration of hydronium ions in an aqueous solution by removing water from said aqueous solution, said apparatus comprising:

• a container arranged for holding said solution;
• means for reducing temperature of said solution in said container to a temperature selected from a range between 25° F. to 28° F. wherein one portion of said solution remains liquid and another portion of said solution is frozen;
• means for agitating said solution whereby said said another portion is dispersed in said first portion;
• means for filtering said another portion from said one portion;
