SW30HRLE-400

Summary

Product identification

The FilmTec™ SW30HRLE-400 is a spiral-wound element with a polyamide thin-film composite membrane, designed for seawater reverse osmosis (RO) systems. It aims to reduce capital and operation costs by offering a combination of high rejection and low energy requirements, suitable for medium- and high-salinity feedwater.

Benefits include:

• Optimization of operating cost through lower energy consumption or capital cost through higher productivity at lower operating fluxes.
• High NaCl and boron rejection to help meet World Health Organization (WHO) and other drinking water standards.
• Effective use in permeate staged seawater desalination systems without impairing downstream performance.
• High performance over the operating lifetime without oxidative post-treatments, allowing for cleaning over a wider pH range (1 – 13).
• Automated, precision fabrication with more shorter membrane leaves to reduce fouling and maximize efficiency.

Product specifications

These values are normalized to the following conditions: 32,000 ppm NaCl, 5 ppm boron, 800 psi (5.5 MPa), 77°F (25°C), pH 8, 8% recovery.

• Active Area: 400 ft² (37 m²)
• Feed Spacer Thickness: 28 mil
• Permeate Flowrate: 7,500 gpd (28 m³/d)
• Stabilized Boron Rejection: 92 %
• Stabilized Salt Rejection: 99.80 %
• Minimum Salt Rejection: 99.65 %

Permeate flows for individual elements may vary ± 15%. Stabilized salt rejection is generally achieved within 24 – 48 hours of continuous use. Active area is guaranteed ± 5%.

Mechanical / hydraulic

Dimensions – inches (mm):

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

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

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
  • The presence of free chlorine and other oxidizing agents can cause premature membrane failure. Oxidation damage is not covered under warranty. Pretreatment to remove residual free chlorine is recommended.

Additional important information

• The use of this product alone does not guarantee the removal of cysts and pathogens from water; this depends on the 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.
