Purolite FerrlX Resin

Purolite’s FerrlX A33E resin is a direct replacement for E33 media with regeneration, extraction, and loading services available

Ever at the forefront of removing contaminants from potable and groundwater, Purolite meets the challenges of water treatment and purification head-on with new solutions for hexavalent chromium, arsenic and nitrates removal and disinfection byproduct control.

Purolite’s FerrlX A33E resin, a direct replacement for Bayoxide E33, is manufactured and regenerated in the United States. Regeneration reduces operating costs as much as 50% and eliminates the potential of hazardous waste disposal.


FerrlX – Modified Resin Infused with Iron Oxide Particles for Removing Arsenic from Water


Purolite® FerrIX™ A33E is an iron-infused anion resin that uses iron oxide to complex and remove Arsenic III and Arsenic V from water. FerrIX™ A33E reduces arsenic levels to < 2 ppb and is ideal for municipal treatment plants, point-of-entry (POE) and point-of-use (POU) systems. It is compatible with most existing lead-lag or parallel design configurations and is recommended for either single use or for applications needing off-site regeneration.


The highly porous FerrIX™ A33E 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.


Water treatment systems incorporating FerrIX™ A33E resin are designed and operated using the same engineering guidelines as conventional ion exchange resins. Purolite’s proprietary simulator accurately calculates the throughput capacity for treating the water supply, eliminating the need for extensive field trials. Call us at 480-998-4097 or contact us online today to see what we can do for you!


Upon prior arrangement with Purolite®, exhausted FerrIX™ A33E can be returned to Purolite® for regeneration under an NSF/ANSI 61 approved process that utilizes full chain of custody documentation. (Note: currently this service is only available in the USA).
