A850-50-BOX, =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.
