A system eliminating boron using an electrodeionizer is provided to minimize a maintenance cost and to simplify a series of apparatus by supplying and disposing again only a part of the fresh water filtered out by the sea water zone porous membrane unit to an electrodeionizer. A system eliminating boron using an electrodeionizer(10) contains a seawater reverse osmotic membrane unit(12), a water softener(14), an electrodeionizer(15), a fresh water bypass pipe(16) and an enriched water bypass pipe(17). The seawater reverse osmotic membrane unit accommodates filtering seawater, and filters and removes the boron included in the filtered seawater. The water softener accommodates the fresh water which is ejected by the seawater reverse osmotic membrane unit and removes hardness components. The electrodeionizer accommodates the fresh water ejected by the water softener and removes the residue boron and ionic components. The fresh water bypass pipe connects an evacuation pipeline of the electrodeionizer and an inflow pipe passage of the water softener. |
