Amberlite PWA6

Summary

Product Identification

AMBERLITE™ PWA6 Resin is an anion exchange resin designed for drinking water applications, specifically for the removal of nitrate and perchlorate.

Properties

• Physical form: Pale yellow translucent beads
• Matrix: Cross linked copolymer
• Total exchange capacity: ≥ 1.25 eq/L
• Moisture holding capacity: 49 – 60%
• Shipping weight: 670 kg/m³ (42 lb/ft³)
• Particle size (screen grading): 0.3 – 1.2 mm (16 – 50 mesh US Std Screens)
• Fines content: <0.300 mm: 1% max

Suggested Operating Conditions

• Maximum operating temperature: 75 °C (170 °F)
• Minimum bed depth: 610 mm (24 inches)
• Typical service flow rate: 5 – 40 BV/h* (0.6 – 5 gpm/ft³)
• Regenerant (100% basis): NaCl
  • Concentration: 6 – 12%
  • Minimum level: 80 g/L (5 lbs/ft³)
• Minimum contact time: 30 minutes

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

Commissioning and Limits of Use

• For potable water applications, a full regeneration cycle with 120 g of NaCl per liter of resin, followed by an adequate rinse, is recommended.
• For non-regenerable applications, an initial commissioning rinse of 10 bed volumes of water at ambient temperature is suitable.
• Operating capacity is dependent on operating and feed water conditions.

Regulatory

• Certified to ANSI / NSF Standard 61 for drinking water components.
• Manufactured in ISO 9001 certified facilities.
