Ion exchange resin refining technology and system

The cleaning process of semiconductor manufacturing and nuclear power stations require ultrapure water, in which impurities have been reduced to the extreme. Used for manufacturing this ultrapure water, ion exchange resins require special refining processes including elution reduction.

Organo is the only water treatment engineering manufacturer in Japan that has a factory dedicated to refining ion exchange resins, namely the Tsukuba Factory located in the industrial park of the Techno Park Toyosato in the city of Tsukuba, Ibaraki Prefecture. In operation since 1990, it is one of the world’s largest factories exclusively refining ion exchange resins. It manufactures refined ion exchange resins by processing the Amberlight resin produced by U.S. firm Rohm and Haas in accordance with Organo’s proprietary refining method.

The refined ion exchange resins are customized to the specifications designated by different customers. Ultrapure water manufacturing systems designed and built by Organo satisfy the wide-ranging needs of numerous customers.
