FilmTec™ SW30HRLE-400

Summary

Product identification

The FilmTec™ SW30HRLE-400 is a seawater reverse osmosis (RO) element. It is a spiral-wound element featuring a polyamide thin-film composite membrane.

Description & Benefits

These elements are designed to reduce the capital and operation costs of seawater RO systems by offering a combination of high rejection and low energy requirements, suitable for medium- and high-salinity feedwater.

Benefits include:

• Optimized operating cost through lower energy consumption or optimized 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 the performance of the downstream stage.
• High performance over the operating lifetime without oxidative posttreatments, making elements more durable and cleanable over a wider pH range (1–13).
• Automated, precision fabrication with a greater number of shorter membrane leaves to reduce overall fouling and maximize element efficiency.

Typical Properties

• 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%

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

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.

Mechanical / hydraulic

• Element Length (A): 40.0 in (1,016 mm)
• Element Internal Diameter (B): 1.125 ID (29 ID mm)
• Element Outer Diameter (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

Important Information

• It is recommended to review usage guidelines, start-up sequences, and storage/shipping information prior to use or storage.
• The use of this product alone does not guarantee the removal of cysts and pathogens; 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.
