Amberlite™ PWA2 is the first potable water grade anion exchange resin designed for specific removal of perchlorate from drinking water.

The unique structure of Amberlite PWA2 is highly selective for the perchlorate ion. This means that unlike conventional anion exchangers, Amberlite PWA2 continues to show excellent perchlorate removal in the presence of competing background ions such as sulfate and nitrate.

These characteristics make Amberlite PWA2 the perfect choice for a simple, economical, once through purification process, which can be applied in municipal water treatment systems or in point-of-entry applications.
