METHOD OF PREPARING CURATIVE DRINKING WATER AND APPARATUS FOR EFFECTING SAME Russian patent published in 1994 - IPC

FIELD: water processing. SUBSTANCE: new method prescribed preparing ice from starting water by freezing water vapor at temperature not exceeding +10 C. For this purpose, vacuum was set up in housing to enable vigorously evolving vapor to condense and freeze on surfaces of freezer pipes, resultant ice was allowed to thaw and at the same time exposed to ultraviolet and infrared radiation and thawed-ice water was then saturated with either gas or gas mixture (for example, carbon dioxide or mixture of carbon dioxide and xenon) admitted in housing via apparatus branch pipe. Thus prepared drinking water possessed curative properties. EFFECT: ameliorated biological qualities of drinking water. 1 cl, 2 dwg
