摘要
PURPOSE: A manufacturing method of mineral water which removed the anion with a nanofiltration membrane and electrodialysis is provided to remarkably remove the anion included in the mineral water and manufacturing the mineral water which improved the eating feeling, thereby fitting the rate of magnesium and potassium which is useful for the body in optimum state(approximately 3:1). CONSTITUTION: The manufacturing method of mineral water which removed the anion comprised next; a step of obtaining the concentrated water(120) including ion component and desalted water which the ion component is removed by letting a deep sea water to pass through the osmosis membrane; a step of dividing calcium salt crystallization by heat-concentrating and filtering the concentration water to a first evaporator, a step of obtaining the concentration water which salt is removed by heat-concentrating and filtering the concentration water which the calcium crystallization is divided with a second evaporator, a step of obtaining NF permeated water which negative ion with the mineral concentration water to be removed by manufacturing the mineral concentration diluted water as mixing the desalted water and mineral concentration water and enabling the mineral concentration dilute water to the NF having negative ion, a step of obtaining the mixed solution by mixing the calcium salt crystallization with desalted water, a step of obtaining the mineral water by mixing the NF permeated water, the desalted water and the calcium solution.
