FerrIX™ A33E is a highly porous hybrid anion ion exchange resin infused with iron oxide for efficient, selective removal of arsenic. Porous beads enable maximum utilization of the infused iron. Superior bead strength prevents the creation of fines during loading and the service cycle. Pressure drop remains low and backwash is minimized, reducing water loss and preventing arsenic-laden fine discharge into the sewer. FerrIX A33E can be used in most existing lead-lag or parallel configurations.
