Amberlite PWA5
PDF datasheet mirror for Amberlite PWA5 (Rohm & Haas). Verify with OEM before design.
Summary
Product identification
AMBERLITE™ PWA5 Resin
- Drinking Water Grade
- Nitrate Selective
AMBERLITE PWA5 resin is a strongly basic anion exchange resin designed for selective nitrate removal from drinking water, preferentially removing nitrate over sulfate. It is suitable for regenerable nitrate removal processes in municipal water treatment 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
Contact your Rohm and Haas representative for system design and application testing details.
- 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)*
- *1 BV (Bed Volume) = 1 m³ solution per m³ resin
Regenerant (100% basis)
- Type: NaCl
- Concentration: 6 – 12%
- Minimum level: 80 g/L (5 lbs/ft³)
- Minimum contact time: 20 minutes
Commissioning and Limits of Use
AMBERLITE PWA5 resin is suitable for potable water applications after a full regeneration cycle using 120 g of NaCl per liter of resin, followed by adequate rinsing. Operating capacity depends on operating and feed water conditions.
Regulatory
- Certified to ANSI/NSF Standard 61 for drinking water components.
- Approved for use in public water supplies in the UK.
- Manufactured in ISO 9001 certified facilities.
Hydraulic Characteristics
Pressure drop and bed expansion data are provided in figures within the original document.
- Pressure Drop: Shown as a function of flow rate and water temperature (Figures 1 & 2). Data is valid at the start of a service run with clean water and a correctly classified bed.
- Bed Expansion: Shown as a function of backwash flow rate and water temperature (Figures 3 & 4).
Disclaimer: This extraction may miss figures, footnotes, or revisions. Contractual data must match the OEM PDF revision used on the project.
