Three-layer Bed Water-Purification System Macroporous Type I Strongly Basic Polystyrene Anion Exchange Resin


D201TB is a premium grade strong-basic styrene-based anion exchange resin of the macroporous type I that contains quaternary amine functional groups, synthesized by special technology. Characterized by the high intensity and solid structure of its macropore, excellent regeneration efficiency as well as strong rinse capability, this resin is specialized in exchanging both strong and weak negative-polar &nonpolar organic molecules as well asacids radicals of inorganic salts, performance of which is qualified enough to compete equivalent model AmberLite™ IRA900.

Stacking by specific gravity of resin beds from light to heavy, D201TB often overlies on the very top for its lighter moisture true density while the heavy cation-bed is placed on the bottom. With adding extra inert-resin bed of medium density in between, altogether a three-layer bed water treatment system is fully configured to process water demineralization &decolorization for pure water, ultrapure water and condensed water preparations within various industries.
