Purolite A850 is a gel-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 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.

This resin is often used with Purolite C100H (cation load) loaded into another column

Demineralization Resins are used to reduce the TDS (polishing the water).

The TDS from a RO unit is not always as low as required so using DI resin will bring the TDS down to zero.
