FilmTec™ SW30XLE-400

Summary

Product identification

The FilmTec™ SW30XLE-400 Element is a premium seawater reverse osmosis (RO) element. It offers a combination of productivity and rejection, suitable for two-pass seawater designs and high Total Dissolved Solids (TDS) brackish water applications.

Product Type

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

Typical Properties

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. Permeate flows for individual elements may vary ± 15%. Minimum Salt Rejection is 99.6%. Stabilized salt rejection is generally achieved within 24–48 hours of continuous use.

• Active Area: 400 ft² (37 m²)
• Feed Spacer Thickness: 28 mil
• Permeate Flowrate: 9,000 gpd (34 m³/d)
• Stabilized Boron Rejection: 91.5%
• Stabilized Salt Rejection: 99.8%

Dimensions

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

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

Operating and Cleaning 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

Additional Important Information

• 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.
