Method for preparing mineral water with high hardness using deep sea water or saline groundwater

摘要

The present invention relates to a method for producing mineral water of high hardness from deep ocean water or salt ground water and to a mineral water of high hardness produced by the method. The present invention provides a method for effectively providing chlorine ions, sulfate ions, and impurities in a mineral concentrated liquid, thereby making it possible to produce a hardened mineral water having excellent cooling feel. In addition, the present invention provides a purification method for effectively removing a salt component and calcium carbonate from a calcium salt crystal, thereby making it possible to produce a high-hardness mineral water having excellent cooling sensation.
