Abstract: A water treatment apparatus includes a first ion removal module including a first cation exchange membrane, a first anion exchange membrane, and a first deionization channel therebetween; a second ion removal module including a second cation exchange membrane, a second anion exchange membrane, and a second deionization channel therebetween; and a fluid separation device to separate a fluid, discharged from the first deionization channel, and to guide the fluid. The fluid separation device includes an outer guide to guide a portion of the fluid discharged from the first deionization channel to an outside of the second deionization channel, and a center guide to guide another portion of the fluid from the first deionization channel to the second deionization channel, and the center guide arranged inside of the outer guide.
