Purolite A850 is a gel-type 1 strong base anion exchange resin with an acrylic matrix. The acrylic matrix ensures excellent removal of organic matter from a water supply in conjunction with its reversible removal upon regeneration. This resin is regenerated very efficiently with lower levels of sodium hydroxide than those required for a polystyrene based type 1 resin, and yet it has a comparable ability to remove weaker acids including carbonic acid and silica. Its use in combination with a polystyrene based resin (for instance in a mixed bed positioned after the anion unit) can often result in the removal of a wider spectrum of organic compounds than either type of anion resin alone.ApplicationOrganics ;Tannin Removal and Demineralization - Excellent Resistance to Fouling Polymer StructureGel Polyacrylic crosslinked with divinylbenzene AppearanceSpherical beads Functional GroupQuaternary Ammonium Ionic Form as ShippedCl- Total Capacity (min.)1.25 eq/l (27.3 Kgr/ft3) (Cl- form) Moisture Retention, Cl- Form57 - 62 % Particle Size Range300 - 1200 µm <300 µm (max.)1 % Uniformity Coefficient (max.)1.7 Irreversible Swelling (max.)10 % Reversible Swelling, Cl- ?
