PROBLEM TO BE SOLVED: To accelerate the deposition of dissolved components and to smoothly and surely deposit the dissolved components from high temperature and pressure water by providing a deposition accelerating means for locally enhancing a flow rate and causing a change of pressure in the high temperature and high pressure water, in the purifying method depositing the dissolved component from the high temperature and high pressure water. SOLUTION: The high temperature and high pressure water purifying device 10 is provided with parallel-connected two set of units 20 consisting of valves 11, 16, a flow rate meter 12, pressure meters 13, 15, a thermometer 14, and a filter chamber 1 to a main line 30 via valves 31, 32, is assembled in a high temperature and high pressure water plant such as a boiler. In this case, a pair of metallic porous filters are attached in the filter chamber 1. In the case that the high temperature and high pressure water flows from the main line 30, a hole size of the filter of the filter chamber 1 is made narrow and the flow rate is made faster and a change of pressure is locally generated, thus deposition phenomenon of the dissolved metallic component in the high temperature and high pressure water is accelerated and the component is suspended so that ionic iron and suspended iron are easily collected.
