Ion Exchange Resin Becomes NSF/ANSI Certified

The Water Quality Association recently certified Purolite's A532E perchlorate selective resin under the NSF/ANSI 61 Standard for use in drinking water. This is the highest capacity resin for the removal of oxy-anions such as perchlorate.

Perchlorate affects the water supply of 20 million people located in 20 states. It has been shown to interfere with iodine uptake by the thyroid gland, reducing thyroid hormone production and impacting metabolism and growth.

Purolite A532E allows for long run-lengths -- meaning less frequent change outs, a reduction in waste disposal costs, less downtime and lower treatment costs. The resin also removes other oxy-anions such as pertechnetate and can be retrofitted into existing plants using alternative media, allowing this technology to be adopted quickly throughout the water treatment industry.

Bala Cynwyd, Pa.-based Purolite Corporation was founded in 1981 and is a leading manufacturer of ion exchange, catalyst, adsorbent and specialty resins.
