Amberlite PWA5

Summary

Product identification

AMBERLITE™ PWA5 Resin is a drinking water grade, nitrate-selective, strongly basic anion exchange resin. It is designed for selective nitrate removal from drinking waters, preferentially to sulfate, and is compatible with the Advanced Amberpack™ Municipal system.

Properties

• Matrix: Cross-linked copolymer
• Physical form: Cream beads
• Total exchange capacity: ≥ 1.0 eq/L
• Moisture holding capacity: 52 – 58%
• Shipping weight: 690 kg/m³ (43 lb/ft³)
• Particle size:
  • Screen grading: 0.3 – 1.2 mm (16 – 50 mesh US Std Screens)
  • Fines content (<0.300 mm): 0.3% 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: 20 minutes

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

Commissioning and limits of use

AMBERLITE PWA5 resin is suitable for potable water applications after a full regeneration cycle with 120 g NaCl per liter of resin, followed by adequate rinsing. The operating capacity depends on operating and feed water conditions.

Hydraulic characteristics

Pressure drop and bed expansion data are presented in figures within the original document. These figures show the relationship between flow rate, water temperature, pressure drop, and bed expansion.

Regulatory

AMBERLITE PWA5 resin is certified to ANSI/NSF Standard 61 for drinking water components and approved for use in public water supplies in the UK. Resin products are manufactured in ISO 9001 certified facilities.
