• Ionic form as shipped: Free base (FB)
• Total exchange capacity: ≥ 1.25 eq/L (FB form)
• Moisture holding capacity: 57 to 63% (FB form)
• Shipping weight: 670 g/L
• Specific gravity: 1.040 to 1.060 (FB form)
• Particle size:
  • Uniformity coefficient: ≤ 1.80
  • Harmonic mean size: 0.550 to 0.750 mm
  • Particles < 0.300 mm: 1.0% max
• Reversible swelling: FB → Cl- ≤ 15%

Suggested operating conditions

• Maximum operating temperature: 60 °C
• Minimum bed depth: 700 mm
• Service flow rate: 5 to 40 BV*/h
• Regenerant: NaOH, NH₃, Na₂CO₃
  • Level (% of ionic load): 120 (NaOH), 150 (NH₃), 200 (Na₂CO₃)
  • Concentration (%): 2 to 4 (NaOH), 2 to 6 (NH₃), 5 to 8 (Na₂CO₃)
• Minimum contact time: 30 minutes
• Rinse:
  • Slow rinse: 2 BV at regeneration flow rate

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

Hydraulic Characteristics

Figures 1 and 2 in the original document provide data on bed expansion and pressure drop, respectively, as functions of backwash flow rate, service flow rate, and water temperature. These figures are valid for water treatment and may need correction for other solutions.

Limits of Use

AMBERLITE IRA96 resin is suitable for industrial uses. For pharmaceutical, food processing, or potable water applications, consult Rohm and Haas for advice on resin selection and operating conditions.
