A water treatment apparatus includes a primary column having an iodine disinfection layer and an activated carbon layer juxtapositionally provided in the primary column for killing bacteria and for absorbing odors in a feed water, and a secondary column adjacent to and connected to the primary column and having an ion exchange layer, and a mineralizing layer juxtapositionally installed in the secondary column for alternatively removing ions from the water, or for adding minerals into the treated water for health reason as manipulated by a switching valve device having a first valve and a second valve which are simultaneously operated for selectively opening the first valve for directing the water to be mineralized but closing the second valve for interrupting the water into the ion exchange resins if only a mineralized water is required.
