Abstract:
The present invention relates to an electro-deionization water treatment apparatus. The electro-deionization water treatment apparatus according to the present invention comprises: an electro-deionization unit for adsorbing ions in a source water during purified water extraction and desorbing the adsorbed ions during a reclaiming process; a reclaimed water producing unit comprising a storage part, for storing purified water filtered by the electro-deionization unit, and an antiscalant supply part, supported on the storage part and equipped with an antiscalant, and for producing reclaimed water by dissolving the antiscalant in the purified water stored in the storage part; and a control unit for controlling the electro-deionization unit. The control unit controls a valve for forming a flow path enabling the reclaimed water to flow into the electro-deionization unit during the reclaiming process of the electro-deionization unit.
