DETERGENT-FREE CLEANSING WATER, PROCESS AND APPARATUS FOR PRODUCING THE CLEANSING WATER, AND METHOD OF SEPARATING EMULSION FORMED BY USING THE CLEANSING WATER INTO WATER AND OIL

摘要

A cleansing water containing hydroxyl ions (H3O2-) and hydronium ions (H3O+) is produced by passing water through soft water generators (10) and (12) each containing an ion-exchange resin (32) and an ion generator (14) containing a tourmaline mixture (46) comprising tourmaline and metal, said generators (10, 12 and 14) being interconnected in this order, to thereby bring water into contact with the resin (32) and the mixture (46) one by one. The cleansing water forms, after being used to wash off dirts such as oil, an O/W emulsion comprising the hydroxyl and hydronium ions and the oil enclosed by the ions. When this emulsion is mixed with hard water such as tap water, the hydroxyl and hydronium ions are converted into water, whereby the emulsion is separated into oil and oil-free water. IMAGE
