Purolite A860 Tannin Removal Anion Resin, 1.0 Cubic Foot

Purolite A860 is a Macroporous Type I 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 their reversible removal upon regeneration. This resin is regenerated very efficiently with lower levels of sodium hydroxide than those required for a polystyrene based type I 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, and is particularly resistant to organic fouling, even where loadings are relatively high.

Packaging
- Packaged to 1.0 cubic foot container
- Approx. 42-46 pounds of resin

Features & Benefits
     - High Capacity For Organics: Macroporous polyacrylic crosslinked with divinylbenzene provides the highest possible capacity for organics when operated in the chloride cycle
     - Excellent Regeneration Efficiency: Superior kinetics and low chloride selectivity yields high regeneration efficiency
     - Complies With US FDA Regulations: Conforms to paragraph 21CFR173.25 of the Food Additives Regulations of the US FDA

Applications:
     - Organic Trap: A860 has the highest possible capacity for tannins and other naturally occurring organic matter (NOM) due to its acrylic polymer backbone and macroporous physical structure. Tannins and similar naturally occurring organics cause most of the color in potable waters. A860 removes these substances and is easily regenerated with sodium chloride, in the same fashion as a water softener. Organic trap resins should be regenerated frequently to prevent the NOM from building up inside the resin beads and eventually causing fouling. For industrial applications it is sometimes useful to add a little caustic to the brine in order to increase capacity and reduce leakage.
