Franklin FWXA213 Macroporous Strong Base Anion Resin Type I – Tannin & Organic Removal, Demineralization Media

Macroporous Type I Anion Resin for Tannins, Organics & Fouling Control

The Franklin FWXA213 Strong Base Anion Resin Type I is a premium-grade macroporous ion exchange resin engineered for organic removal, tannin reduction, and demineralization system protection. Built on a polyacrylic matrix with Type I quaternary amine functional groups (Trimethylamine), this resin is specifically designed to adsorb dissolved organic contaminants that standard gel resins cannot effectively remove.

Its macroporous structure provides increased surface area and pore volume, allowing it to capture large organic molecules such as tannins and humic substances, while maintaining strong resistance to oxidation, osmotic shock, and mechanical degradation.

FWXA213 is widely used in multi-bed demineralization systems to prevent organic fouling, significantly extending the life and performance of downstream resins.

Why Macroporous Resin Matters

If organics are in the water, standard resin isn’t enough.

FWXA213 is built for exactly that problem:

• Removes tannins and dissolved organics that cause color and fouling
• Prevents organic fouling in mixed bed systems
• Maintains performance in high organic load environments
• Releases organics more effectively during regeneration

This is not a general-purpose resin—it’s a problem-solving resin.

Typical Applications

• Tannin removal from well water
• Organic scavenging in industrial systems
• Pre-treatment for demineralization systems
• Mixed bed protection (prevents fouling)
• Sugar decolorization processes
• High organic content water treatment

Why Choose FWXA213 Over Standard Anion Resin

Most buyers make the wrong call and use gel resin for organics—that fails.

FWXA213 fixes that:

• Gel resin → limited organic removal
• FWXA213 → designed specifically for organic adsorption and release

Trade-off:

• Slightly lower exchange capacity vs gel resin
• Significantly better real-world performance in organic-heavy water

Frequently Asked Questions (FAQs)

What does this resin remove?

Tannins, humic substances, and other dissolved organic contaminants.

Is this a standard anion resin?

No. It is a macroporous specialty resin designed for organics, not just ion exchange.

Can this be used in demineralization systems?

Yes. It is commonly used as a pre-treatment resin to prevent fouling of primary resins.

Why use macroporous instead of gel resin?

Macroporous resins have larger pore structures, allowing them to capture larger organic molecules.

Can this be used for sugar processing?

Yes. It is suitable for sugar decolorization applications.
