PREPARATION OF DRINKING WATER COMPRISING ULTRA-PURE WATER FROM TAP WATER, GROUND WATER AND RIVER WATER

摘要

PURPOSE:To prepare ultra-pure water inexpensively by a mass production system, by applying magnetization treatment to tap water or ground water and purifying the treated water by activated carbon before applying hermatypic coral treatment and ultrashort wave treatment. CONSTITUTION:Properties of tap water, ground water and river water are changed by the actions of the magnetic fields of a cast magnet or a permanent magnet other than the cast magnet of 2,500G or more and an electromagnet of 5,000G and the treated water is subsequently purified by activated carbon. Succeedingly, the purified water is treated by hermatypic coral to perform pH adjustment, the removal of carbon dioxide or hydrogen sulfide and the enhancement of transparency and, thereafter, for example, ultrashort wave treatment for transmitting ultrashort waves with oscillation frequency of 392241.6 megahertz for 30min is performed. By this method, pure and tasteful water can be obtained economically.
