IMAC HP336

Summary

Product identification

IMAC® HP336 is a weak acid cation exchange resin containing carboxylic groups on an acrylic matrix. It is designed for potable water dealkalisation and treatment of waters used in food industries.

Properties

• Matrix: Polyacrylic
• Functional groups: -COO⁻
• Physical form: Opaque beads
• Ionic form as shipped: H⁺
• Total exchange capacity: ≥ 3.90 eq/L (H⁺ form)
• Moisture holding capacity: 54 to 58% (H⁺ form)
• Specific gravity: 1.14 to 1.18 (H⁺ form)
• Shipping weight: 700 g/L
• Particle size:
  • Uniformity coefficient: ≤ 1.9
  • Harmonic mean size: 550 to 750 µm
  • Fine contents (< 0.300 mm): 3.0 % max
  • Coarse beads (> 1.180 mm): 5.0 % max
• Maximum reversible swelling: H⁺ → Na⁺: about 60 %
• Chemical resistance: Sensitive to oxidants. Max. 0.1 to 0.2 ppm in the inlet water.

Suggested Operating Conditions

• Minimum bed depth: 700 mm
• Service flow rate: 5 to 40 BV*/h
• Regenerant:
  • HCl:
    • Concentration: 2 to 5 %
    • Level: 110 %
  • H₂SO₄:
    • Concentration: 0.5 to 0.8 %
    • Level: 110 %
• Regenerant flow rate: 2 to 8 BV
• Minimum contact time: 30 minutes
• Rinse requirements: About 10 BV

*1 BV (Bed Volume) = 1 m³ solution per m³ resin

Conditioning

IMAC HP336 is ready to use if stored at a temperature of less than 25°C, protected from UV radiation, and used within 6 months of the production date. A 20 bed-volume rinse with the water to be treated is required at commissioning.

Quality Control

All Imac HP resins are manufactured and purified for non-industrial applications. Batches are analyzed for physical and chemical properties, substance release in treated water (including TOC), and total microbial count.
