Extrepure Cation Resin

Technical Specifications

General Specifications

• Type: Strong Acid Cation Exchange Resin
• Matrix: Polystyrene crosslinked with divinylbenzene (DVB)
• Functional Group: Sulfonic Acid (-SO₃H)
• Appearance: Golden yellow, spherical beads
• Ionic Form as Shipped: Sodium (Na⁺)

Performance Parameters

Applications

• Water Softening: Removal of calcium and magnesium ions to prevent scale formation.
• Demineralization: Paired with anion resins for complete removal of dissolved solids.
• Pre-Treatment for RO Systems: Protects membranes by reducing hardness and scaling potential.
• Boiler Feed Water: Ensures water quality for high-pressure boiler operations.

Features and Benefits

• High Exchange Capacity: Efficient removal of hardness ions for superior softening performance.
• Durable Structure: Resists physical, chemical, and thermal stress for extended resin life.
• Uniform Beads: Ensures consistent flow and regeneration efficiency.
• Wide Compatibility: Suitable for a range of water treatment systems and conditions.
• Regeneration Efficiency: Operates effectively with common regenerants like NaCl or KCl.

Usage Guidelines

System Design and Sizing

• Bed Depth: 24–36 inches (60–90 cm)
• Service Flow Rate: 10–40 m³/m²/h (4–15 gpm/ft²)
• Regeneration Flow Rate: 2–8 m³/m²/h (1–3 gpm/ft²)

Regeneration Guidelines

• Use 10–15% salt solution (NaCl or KCl) for regeneration.
• Recommended regeneration dosage: 150–200 g/L of resin.
• Rinse thoroughly after regeneration to prevent excess salt in treated water.
