Purolite Nitrate Select Resin, 1 CF Box

Purolite A520E Nitrate Select Resin, supplied here in a 1 cubic foot box, is a macroporous strong base anion resin engineered specifically to remove nitrates from drinking water in both residential and community water systems. Its nitrate-selective chemistry targets nitrate ions even in the presence of competing sulfate, helping bring treated water within safe limits for potable use, a key concern for wells and supplies affected by agricultural runoff.

Built for nitrate removal

A defining advantage of this Purolite media is that it avoids nitrate dumping at the end of the service run, a common problem with conventional anion resins where displaced nitrate can spike sharply in the treated water just before regeneration. By preventing that spike, A520E delivers safer, more predictable operation and noticeably longer service runs between regenerations, which lowers the day-to-day operating burden for system owners and operators.

• Regenerated with common sodium chloride brine
• No nitrate dumping at end of service for safer operation
• Volume: 1 cubic foot box; weight approximately 44.6 lbs each

Because A520E regenerates with ordinary salt brine, it integrates easily into softener-style control valves and brine systems that water-treatment installers already know well, simplifying both initial setup and ongoing maintenance. The macroporous matrix supports good kinetics and strong resistance to fouling, helping the resin maintain capacity across the varied water chemistries found in private wells and small municipal systems.

For homeowners and small communities facing elevated nitrate levels, this Purolite Nitrate Select Resin offers a proven ion exchange solution that pairs longer run lengths with the reassurance of consistent, safe treated water. Sizing the bed correctly and following recommended regeneration practices ensures reliable nitrate reduction throughout the resin's service life, making it a dependable choice for nitrate-impacted supplies.

When commissioning a nitrate system, operators should confirm the salt dosage and run length suit their incoming nitrate and sulfate levels, as these factors shape both capacity and regeneration frequency. With its proven nitrate selectivity and brine regeneration, this Purolite A520E media gives water professionals a reliable, salt-compatible tool for protecting families and communities from elevated nitrate in their drinking water.
