New high-capacity ion exchange resin cuts the cost of perchlorate removal
The Water Quality Association recently certified Purolite’s A532E perchlorate selective resin under the NSF/ANSI Standard 61 for use in drinking water. This is the highest capacity resin for the removal of oxyanions such as perchlorate.
Perchlorate is a major problem in the U.S. and affects the water supply of 20 million people 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.
The resin allows for long run lengths meaning less frequent changeouts, a reduction in waste disposal costs, less downtime and lower treatment costs. In addition to perchlorate, the resin will also remove other oxyanions such as pertechnetate, and can be retrofitted into existing plants currently using alternative media.
