Description
A520E Food Grade Nitrate Removal Media (25L) is a premium-grade; macro porous strong base anion exchange resin explicitly engineered for the selective removal of nitrates from potable water supplies. It features a unique chemistry that prioritizes nitrate exchange even when high levels of sulfates are present. This makes it a highly reliable solution for domestic boreholes, wells, and municipal systems prone to agricultural contamination.
Core Mechanism and Selectivity
- Sulfate Blindness: Standard anion resins lose efficiency because sulfates displace captured nitrates.
- Fixed Retention: The macro reticulated structure of this resin retains a high affinity for nitrate ions.
- No Nitrate Dumping: It prevents “dumping”, a phenomenon where a resin suddenly releases harmful concentrations of nitrates back into the treated stream.
