<P>PROBLEM TO BE SOLVED: To develop new hardness-regulated natural water by regarding that the water content of human body is about 77% in infants, is about 62% in young persons and is about 53% in aged persons, and the mineral content of deep sea water remarked in recent years is approximately equal to the mineral content constituting the human body, and by utilizing such a knowledge. <P>SOLUTION: This hardness-regulated natural water consists of low-hardness land natural water 1 which is taken on land and high-hardness sea natural water 5a which is obtained from the deep sea water 5 of the depth ≥200 m by desalting separation. As the land natural water 1, mineral water 1a taken from underground is used and, for the sea natural water 5a, the deep sea water 5 is at first separated into fresh water 6 and concentrated deep layer water 7 by means of a multistage electrodialysis and, subsequently, the hardness of the hardness regulation natural water is regulated to 20-1,500 by using at least one of concentrated mineral water 8 and concentrated salt water 9 which are obtained by separating the concentrated deep layer water 7. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
