SW30XLE-400

Summary

Product identification

• Product Name: FilmTec™ SW30XLE-400 Element
• Product Type: Seawater Reverse Osmosis Element
• Membrane Type: Spiral-wound element with polyamide thin-film composite membrane
• Key Features:
  • High productivity, with an active area of 400 ft², designed for low total cost of water by optimizing energy consumption, system productivity, and operating flux.
  • Can be effectively used in permeate staged seawater desalination systems without impairing downstream stage performance.
  • Delivers high performance over its operating lifetime without oxidative post-treatments.
  • May be cleaned more effectively over a wider pH range (1 – 13) than other RO elements.
  • Automated, precision fabrication with a greater number of shorter membrane leaves to reduce overall fouling and maximize element efficiency.

Operating limits

• Maximum Operating Temperature: 113°F (45°C)
  • Note: Maximum temperature for continuous operation above pH 10 is 95°F (35°C).
• Maximum Operating Pressure: 1,200 psig (83 bar)
• Maximum Element Pressure Drop: 15 psig (1.0 bar)
• pH Range:
  • Continuous Operation: 2 – 11
  • Short-term Cleaning (30 min): 1 – 13

Feed water

• Maximum Feed Silt Density Index (SDI): SDI 5
• Free Chlorine Tolerance: < 0.1 ppm (DuPont recommends removing residual free chlorine by pretreatment prior to membrane exposure.)

Product water

• Active Area: 400 ft² (37 m²) (guaranteed ± 5%)
• Feed Spacer Thickness: 28 mil
• Permeate Flowrate: 9,000 gpd (34 m³/d) (Individual element flows may vary ± 15%)
• Stabilized Boron Rejection: 91.5%
• Stabilized Salt Rejection: 99.8%
• Minimum Salt Rejection: 99.6%
• Test Conditions (Normalized):
  • 32,000 ppm NaCl
  • 5 ppm boron
  • 800 psi (5.5 MPa) operating pressure
  • 77°F (25°C) temperature
  • pH 8
  • 8% recovery
• Note: Stabilized salt rejection is generally achieved within 24 – 48 hours of continuous use.

Mechanical / hydraulic

• Element Dimensions (Nominal):
  • A: 40.0 inches (1,016 mm)
  • B (ID): 1.125 inches (29 mm)
  • C: 7.9 inches (201 mm)
• Designed to fit a nominal 8-inch (203-mm) I.D. pressure vessel.

Important Operational Notes

• Permeate obtained from the first hour of operation should be discarded.
• The use of this product does not necessarily guarantee the removal of cysts and pathogens from water; effective reduction depends on complete system design, operation, and maintenance.
• This product may be subject to drinking water application restrictions in some countries; users should check the application status before use and sale.
