Purolite (A-520E) Nitrate Selective Resin CF Bag 44 lbs
Purolite A-520E Nitrate Selective Resin
The Purolite A-520E resin is purpose-built for nitrate removal in potable water systems where standard ion exchange resins fall short. Its macroporous polystyrene matrix and specialized functional groups deliver ideal nitrate selectivity even in water with moderate to high sulfate concentrations. Total capacity of 0.90 eq/l (19.65 kGr/ft³) with a mean bead size of 0.60-0.85 mm ensures consistent performance in municipal and commercial applications.
Why A-520E Outperforms Standard Resins
Superior Nitrate Selectivity
Macroporous structure with specialized ion exchange groups preferentially targets nitrates over competing ions, maintaining efficiency even with high sulfate levels
Regulatory Compliance
Produces potable water meeting EU Directive 80/778 (50 mg NO3/l max) and US drinking water standards (45 mg NO3/l max) for safe consumption
Type 1 Quaternary Ammonium
Strong base anion functionality in chloride form provides robust nitrate exchange capacity with reliable regeneration characteristics
Wide Operating Range
Stable across pH 0-14, with optimal operating range of 4.5-8.5 and temperature tolerance up to 100°C (212°F) in chloride form
Consistent Bead Quality
Uniformity coefficient max 1.70 with spherical beads ensures even flow distribution and predictable pressure drop across the resin bed
Commercial Volume
44 lb cubic foot bag with shipping weight 675-705 g/l and specific gravity 1.07 provides convenient handling for system refills and new installations

Designed For Potable Water Nitrate Removal
The Purolite A-520E nitrate selective resin is engineered for municipal water treatment plants, well water remediation systems, and commercial potable water applications where nitrate levels exceed regulatory limits. Ideal for regions with agricultural runoff, high groundwater nitrate concentrations, or where sulfate interference limits the effectiveness of standard anion resins. Compatible with standard ion exchange vessels and regeneration equipment using sodium chloride brine. This resin bed media replaces or supplements existing nitrate removal systems requiring cubic foot quantities. Best performance achieved in systems designed for Type 1 strong base anion exchange with proper backwash, regeneration, and rinse cycles.
Purolite A-520E has been the benchmark for selective nitrate removal in potable water systems worldwide, trusted by water treatment professionals who demand compliance and consistency.
