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.
