4 Purolite Selective Resins
Resins, Media & Chemicals
Purolite A520 Nitrate Selective Resin
A520 is a macro porous strong-base anion resin which is designed for the removal of nitrates from
water for potable processes for both residential and community water systems. Regenerated with brine.
No nitrate dumping at the end of service and longer service runs.
For Nitrate removal in residential and community water systems. Regenerated with brine.

Purolite A850 Tannin Resin
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.

Purolite A860 Tannin Resin
A860 is a macro porous 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. 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.
A macroporous resin for the adsorbtion of soluble tannins that contribute to color and taste in
drinking water.

Purolite Tanex Resin
TANEX is a proprietary blend of special and patented anion exchange resins used for removal of
tannins and organic matter in water used primarily for potable applications. TANEX is useful in reducing
more difficult-to-control organic matter and color that may exist as partially dissolved and partially
colloidal in nature.
Resin for the adsorbtion of soluble tannins that contribute to color and taste in drinking water.

Purolite SST-60 High Efficiency Softening Resin
SST-60 is a high-efficiency softening resin based on gel type shallow-shell technology. Lower hardness
leakage. Significant savings in salt usage. The shorter the diffusion path, the more
rapid the softening exchange occurs. Reducing the depth of penetration required to
cleanse the resin allows for a more complete regeneration and provides a higher,
more efficient utilization of the regenerant. The result is a resin with unsurpassed salt
efficiency, lower leakage and reduced rinse water requirements.
Certified by the WQA to
Gel Type Shallow Shell Technology (SST) resin for softening applications. Lower
NSF/ANSI-61 Standard
hardness leakage. Significant savings in salt usage.
