Purolite A400 Demineralization and Silica Removal Anion Exchange Resin

Documentation

Spec Sheet

Description

• Industrial Water Demineralization:
• Used as the anion component in ion-exchange systems (often paired with a cation resin) to remove dissolved anions (e.g., chloride, sulfate, nitrate, bicarbonate, silica) and produce high-purity water.
• Silica Removal:
• Particularly effective at reducing silica levels in water treatment applications — important in boiler feed water and power plant condensate treatment.
• Mixed and Layered Bed Systems:
• Suitable for both mixed bed and layered bed demineralizers, helping achieve excellent separation and water purity.
• Warm Water Applications:
• Can operate in warm water or where pre-heated regeneration solutions are present, making it versatile in industrial settings.
• High Operating Capacity:
• Has a strong anion exchange capacity, meaning it can remove a large amount of anionic contaminants before needing regeneration.
• Efficient Regeneration:
• Regenerates effectively with common regenerants (e.g., NaOH), which helps reduce chemical use and operational costs.
• Good Kinetic Performance:
• Good exchange kinetics allow efficient ion uptake and discharge at practical flow rates, helping achieve low residual ion levels in treated water.
• Physical Stability:
• Stable gel polystyrene structure resists breakdown and minimizes pressure drop in service, contributing to longer resin life.
• Clear Gel Structure:
• Gel matrix and controlled particle size enable consistent performance and good rinse characteristics after regeneration.
• Regulatory Certifications:
• Halal and Kosher certified
