[0034] During use, the offline hydraulic oil is fed into the sedimentation chamber 2 through the feed pipe 25. First, the entering hydraulic oil is filtered by the filter plate 5, and the solid impurities remain on the upper surface of the filter plate 5. Then, the hydraulic oil is sedimented in the sedimentation chamber 2. The solenoid valve 20 on the drain pipe 17 is opened to discharge the sedimented water in the sedimentation chamber 2. Then, the drain pipe 17 is closed, and the solenoid valve 20 on the first delivery pipe 18 is opened to allow the hydraulic oil in the sedimentation chamber 2 to enter the water absorption chamber 3 through the first delivery pipe 18.
