PROBLEM TO BE SOLVED: To provide a health water including an oceanic mineral component by simplicity at low cost.SOLUTION: A treated water of a river water, a tap water and a rain water or the like are passed in a crushed Ryukyu limestone particle layer, thereby the health water in which an oceanic mineral component abundantly dissolved is obtained. The Ryukyu limestone particle may be a calcination Ryukyu limestone particle in which crushed Ryukyu limestone is calcined at 300-825°C. Moreover, the Ryukyu limestone particle is desirably a mixing particle of the calcination Ryukyu limestone particle in which the Ryukyu limestone is calcined at 300-825°C and the calcination Ryukyu limestone particle in which the crushed Ryukyu limestone is calcined at 825-1,100°C. The treated water is desirably passed in the Ryukyu limestone particle layer after the treated water is passed in an active charcoal layer beforehand.COPYRIGHT: (C)2013,JPO&INPIT【課題】簡易・低コストで海洋ミネラル成分を含む健康水を提供する。【解決手段】破砕した琉球石灰岩粒層中に、水道水、天水、河川水等の被処理水を通水して海洋ミネラル成分が豊富に溶存した健康水を取得する。琉球石灰岩粒は、破砕した琉球石灰岩を300~825℃で仮焼してなる仮焼琉球石灰岩粒であってもよい。また、破砕した琉球石灰岩を300~825℃で仮焼してなる仮焼琉球石灰岩粒と破砕した琉球石灰岩を825~1100℃で焼成してなる仮焼琉球石灰岩粒との混合粒であることも好ましい。予め、被処理水を活性炭粒層中に通水した後、前記琉球石灰岩粒層中に通水することも好ましい。【選択図】なし
