  • Fluid treating method
    Patent number: 4421652
    Abstract: A fluid treating apparatus and method are provided which employ finely subdivided surface active particles arranged in loose bed form and confined within a treating tank by means which prevent the escape of such particles but which permits fluid flow therethrough at a high rate with a minimum pressure drop. In an important embodiment, the apparatus and method of this invention are particularly directed to the treatment of water with fine mesh ion cation exchange resin particles of below 50 mesh size, and preferably 100 to 200 mesh or smaller, measured on a dry basis.
