Abstract: Disclosed is a water treatment device such as a water purifier. In particular, a water treatment device capable of producing sterilizing water is disclosed. The device includes a sterilizing water producing module for electrolyzing raw water to produce sterilizing water, wherein the sterilizing water producing module includes a plurality of first electrodes and a plurality of second electrodes arranged alternately with each other and spaced from each other, wherein the first and second electrodes have opposite polarities to each other, wherein a polarity of each of the first electrode and the second electrode is switchable to between a positive potential and a negative potential, such that the sterilizing water producing module operates such that a positive potential operation and a negative potential operation are alternately repeated, wherein a magnitude of voltage or current applied to the sterilizing water producing module under the negative potential operation is smaller than a magnitude of voltage or current applied to the module under the positive potential operation.
