  • Detergent-free washing water, method and apparatus for making the washing water, and water/oil separation method for separating matters emulsified with the washing water into water and oil phases
    Patent number: 5599455
    Abstract: Washing water containing hydroxyl ions (H.sub.3 O.sub.2.sup.-) and hydronium ions (H.sub.3 O.sub.2.sup.-) is prepared by connecting soft water generators (10), (12) each having an ion exchange resin (32), and an ion generator having a tourmaline mixture of tourmaline and a metal, and passing water through the ion exchange resin (32) and the tourmaline mixture (46). Water emulsified by removing stains such as of oils with the washing water is a kind of O/W emulsion wherein the hydroxyl ions (H.sub.3 O.sub.2.sup.-) and hydronium ions (H.sub.3 O.sub.2.sup.-) have oil wrapped therein. The aqueous O/W emulsion is mixed with hard water such as city water, whereupon the hydroxyl ions (H.sub.3 O.sub.2.sup.-) and hydronium ions (H.sub.3 O.sub.2.sup.-) covering the oil therewith are converted to water, thereby permitting the oil and oil-free water to be separated from each other.
