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.
