Technical publication describing the systems of ion exchange deionization for treating boiler condensate, a major source of feedwater contamination. Proves how it is economically desirable to carry out high flow rate condensate polishing operations through the use of ion-exchange resins such as Amberlite, a high-quality resin produced by the Rohm and Haas Company for use in industrial softening applications when high performance and cost-effective operation is required. Includes photomicrographs and tables. Work is digitized in its entirety. The Rohm and Haas Company was founded in 1907 in Esslingen, Germany through the partnership of German chemist Otto Röhm and German businessman Otto Haas. In 1933, Röhm's experiments with the polymerization of methyl methacrylate led to the creation of a clear, solid plastic sheet, which he trademarked Plexiglas. During World War II, the demand for Plexiglas, which both Allied and Axis forces used for submarine periscopes and aircraft windshields, canopies, and gun turrets, helped transform Rohm and Haas into a major chemical firm.</div>
