Felite™ FS600-P is a Macroporous Type I strong base acrylic anion exchange resin. Due to its acrylic polymer backbone and macroporous physical structure, it gives the highest possible capacity for tannins and other naturally occurring organic matter. Tannins and similar naturally occurring organics cause most of the color in potable waters. The acrylic matrix ensures excellent removal of organic matter from a water supply in conjunction with their reversible removal upon regeneration. Its use in combination with a polystyrene based resin 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.
