PROBLEM TO BE SOLVED: To provide a water treatment apparatus capable of supplying treated water, which is obtained by efficiently treating supplied water in an amount corresponding to the water supply request of a thermal device and capable of efficiently degassing a dissolved gas even if the temperature of the supplied water is lowered. SOLUTION: The water treatment apparatus is equipped with a filter film part for filtering supplied water using a filter film for trapping a corrosion accelerating component for causing the corrosion of the thermal device is provided on the upstream part of the water supply line to the thermal device and a pump for supplying water to the filter film part is provided on the upstream side of the filter film part while a membrane type degassing part for using a gas permeable film for permitting the dissolved gas in the supplied water to permeate is provided on the downstream side thereof. After the corrosion accelerating component is filtered from the water flowing through the water supply line in the filter film part, the dissolved gas is degassed in the membrane type degassing part to supply the degassed water to the thermal device. In this water treatment apparatus, a plurality of filter film parts 2a, 2b and 2c are connected to the water supply line 1 side by side and pumps 3a, 3b and 3c are arranged with respect to the filter film parts 2a, 2b and 2c, and back flow preventing control valves 4a, 4b and 4c are arranged on the down stream side of the back flow preventing 2a, 2b and 2c.
