Description
High-Efficiency Type II Anion Resin for Dealkalization and Nitrate Removal
The Franklin FWXA202 Strong Base Anion Resin Type II is a premium-grade gel-type anion exchange resin designed for water demineralization, dealkalization, and nitrate removal. Built on a polystyrene matrix with Type II quaternary amine functional groups (Dimethylethanolamine), this resin delivers excellent operating capacity and highly efficient regeneration, particularly in systems treating high free mineral acid (FMA) feed water.
FWXA202 is engineered to provide clean operation with no taste or odor contribution, making it ideal for applications where amine odor is unacceptable, including potable water and process water systems.
In chloride form, the resin is highly effective for alkalinity and nitrate removal, while in hydroxide form, it performs in full demineralization systems.
Key Features
- Type II strong base anion (SBA) resin
- Designed for dealkalization, nitrate removal, and demineralization
- High regeneration efficiency vs Type I resins
- Excellent performance in high FMA (free mineral acid) conditions
- Low odor profile – ideal for potable and sensitive applications
- Good operating capacity with reduced chemical usage
- Uniform bead size distribution for consistent flow performance
- Suitable for chloride (Cl⁻) or hydroxide (OH⁻) form operation

Why Choose Type II Anion Resin?
This is where the real differentiation happens.
Compared to Type I anion resins, FWXA202 offers:
- Higher regeneration efficiency → lower chemical consumption
- Better performance in dealkalization applications
- Reduced risk of amine odor carryover
- Improved performance in high FMA water conditions
Trade-off:
- Lower maximum temperature tolerance vs Type I resin
- Best suited for standard and moderate temperature systems
Typical Applications
- Dealkalization systems
- Nitrate removal systems
- Water demineralization (OH⁻ form)
- Municipal and potable water treatment
- Industrial and commercial water systems
- Pre-treatment for boiler and process water
Frequently Asked Questions (FAQs)
What is a Type II anion resin used for?
Primarily for dealkalization, nitrate removal, and demineralization.
What is the difference between Type I and Type II anion resin?
Type II resins offer better regeneration efficiency and lower chemical usage, but operate at lower maximum temperatures.
Can this remove nitrates?
Yes. In chloride form, it is effective for nitrate removal.
Is this suitable for potable water systems?
Yes. It is designed for safe use in drinking water and treatment systems.
Does this resin produce odor?
No. It is specifically designed to be low odor and suitable for sensitive applications.
