(57) [Abstract] [Purpose] An apparatus and method for removing boron dissolved in freshwater obtained by desalination by reverse osmosis or raw water used for water supply by reverse osmosis. In the above, by stabilizing the amount of permeated water of the reverse osmosis membrane and improving the boron removal performance, it is possible to easily and efficiently obtain safe drinking water that satisfies the guideline values of the tap water quality monitoring items. [Structure] Means for removing divalent or higher cations dissolved in water to be treated, means for adjusting the pH of water from which divalent or higher cations have been removed to 9 or higher, and boron removal An apparatus for removing boron in water, characterized by comprising a reverse osmosis membrane separation device for performing the same, and a method for removing boron, characterized by using this apparatus. |
