Purolite Gelular Tannin Res, 1/2 CF Box

A850 is a gelular type 1 strong base anion exchange resin with an acrylic matrix for the adsorption of soluble tannins that contribute to color and taste in drinking water. 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 I resin, and yet it has a comparable ability to remove weaker acids including carbonic acid and silica. It’s used 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.

A860 is a macroporous type 1 strong base anion exchange resin with an acrylic matrix for the adsorbtion of soluble tannins that contribute to color and taste in drinking water. Since is has an acrylic matrix like the A850, it works the same way with the removal of organic matter, regeneration and removing weaker acids. It can also be used is combination with a polystyrene-based resin for the same effects. It is particularly resistant to organic fouling, even where loadings are relatively high.
