Notes on dimensions:

• These elements are bagged dry before shipping.
• Dimension B refers to internal diameters unless specified OD (outside diameter).
• Dimension C (element diameter) is designed for optimum performance in SUEZ pressure vessels. Other pressure vessel dimensions and tolerances may result in excessive bypass and loss of capacity.

Operating limits

• Typical Operating Pressure: 80-135 psig (555 – 931 kPa)
• Typical Operating Flux: 10-25 GFD (15-40 LMH)
• Maximum Operating Pressure: 200 psig (1,379 kPa)
• Clean Water Flux (CWF): 1.3-2.5 gfd/psi (30-60 lmh/bar) at 77°F (25°C)
  • Note: CWF is the rate of water permeability through the membrane after cleaning (CIP) at reproducible temperature and pressure. Monitoring CWF after each cleaning cycle helps determine cleaning effectiveness.
• Maximum Temperature:

  • Clean In Place (CIP): 122°F (50°C)
• pH Range:
  • Continuous operation: 4.0-11.0
  • Clean In Place (CIP): 2.0-11.5
• Maximum Pressure Drop:
  • Over an element: 12 psig (83 kPa)
  • Per housing: 50 psig (345 kPa)
• Chlorine Tolerance: 5,000+ ppm-days
