SW30XHR-400i

Summary

Product identification

FilmTec™ SW30XHR-400 Elements are premium seawater reverse osmosis (RO) elements, representing the highest rejection seawater RO elements in the FilmTec™ Element portfolio.

Product Type Spiral-wound element with polyamide thin-film composite membrane.

Key Benefits

• Very high NaCl and boron rejection to help meet World Health Organization (WHO) and other drinking water standards.
• Guaranteed active area of 400 ft² maximizes productivity and enables accurate system design.
• Effective use in permeate staged seawater desalination systems.
• High performance over the operating lifetime with durability and cleanability over a wider pH range (1 – 13).
• Automated, precision fabrication with a greater number of shorter membrane leaves to reduce fouling and maximize efficiency.

Product water

The following benchmark values are based on test conditions: 32,000 ppm NaCl, 800 psig (5.5 MPa), 77°F (25°C), pH 8, 8% recovery.

• Active Area: 400 ft² (37 m²) (guaranteed ± 5%)
• Feed Spacer Thickness: 28 mil
• Permeate Flowrate: 6,000 gpd (23 m³/d)
  • Permeate flows for individual elements may vary ± 15%.
• Stabilized Boron Rejection: 93%
• Stabilized Salt Rejection: 99.82%
  • Minimum Salt Rejection is 99.70%.
  • Stabilized salt rejection is generally achieved within 24 – 48 hours of continuous use.

Mechanical / hydraulic

The element is designed to fit a nominal 8-inch (203-mm) I.D. pressure vessel.

Dimensions – inches (mm)

• A: 40.0 in (1,016 mm)
• B: 1.125 ID (29 ID)
• C: 7.9 in (201 mm)

Operating limits

• Maximum Operating Temperature: 113°F (45°C)
  • 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
• pH Range – Short-term Cleaning (30 min): 1 – 13
• Maximum Feed Silt Density Index (SDI): SDI 5
• Free Chlorine Tolerance: < 0.1 ppm
  • Presence of free chlorine and other oxidizing agents will cause premature membrane failure. Oxidation damage is not covered under warranty.

Notes for Use

• 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.
• Permeate obtained from the first hour of operation should be discarded.
• This product may be subject to drinking water application restrictions in some countries; check application status before use and sale.
