摘要： The method and apparatus for concentration aqueous solution in accordance with the present invention is characterized in that a hydrophobic porous membrane (2) through which vapor (4) can permeate, but not liquid, is brought into contact with an aqueous solution containing a solute at a concentration of at least 30%, and the water contained in the aqueous solution at the interface with the membrane is evaporated and permeates through the membrane (2). A method and an apparatus of recovering temperature of an aqueous solution comprising an aqueous solution concentration step in which the aqueous solution is in contact with the membrane (2), the water being evaporated; and a dilution step in which the resultant concentrated solution (11) is diluted; wherein a temperature is obtained higher or lower than that of said aqueous solution The method and apparatus for concentrating an aqueous solution can be used as a means or apparatus for concentrating an aqueous solution in a dilution type of heat pump, and absorption type of heat pump or an absorption type of refrigerator. Aqueous solutions for high temperature outputs of dilution systems include aqueous solutions of sulfuric acid, nitric acid, etc., and for low-temperature outputs I include aqueous solutions of potassium nitrate, sodium nitrate, etc. and further for absorption systems include aqueous solutions of NaCℓ0 3 , lithium bromide, etc.

摘要： Projections are removed from the surfaces of ion exchange resin particles by contacting the resin particles with a liquefied gas or supercritical gas in advance. The ion exchange resin thus prepared can remove ions from raw water so thoroughly that the water quality can be improved to that of ultra-pure water.
