METHOD FOR PRODUCING MINERAL WATER FROM MAGMA SEAWATER WITH MINERAL ISOLATION AND BLENDING

摘要

The present invention relates to a method for producing mineral water by using seawater, and, more specifically, to a method for producing mineral water from seawater by mineral isolation and blending. The method for producing mineral water from seawater by mineral isolation and blending of the present invention comprises (a) a step of obtaining ED desalinized water by treating seawater with an electrodialysis device; (b) a step of obtaining R/O condensed water and R/O permeated water by processing the ED desalinized water with a reverse osmosis membrane; (c) a step of precipitating calcium mineral salts and separating by evaporating and concentrating the R/O condensed water; (d) a step of precipitating manganese mineral salts and separating by further evaporating and concentrating the R/O condensed water with calcium mineral salts removed; (e) a step of obtaining calcium mineral water with sulfate ions (SO_4^2-) removed by adding the separated calcium mineral salts to the R/O permeated water, and, then, treating with an electrodialysis device; (f) a step of obtaining mineral water mixed with calcium and manganese by adding the separated manganese mineral salts to the calcium mineral water with sulfate ions (SO_4^2-) removed; and (g) a step of adding drinkable water to the mineral water mixed with calcium and manganese.
