DOW FILMTEC™ SW30HRLE-370/34i element is a durable, high-rejection, high-productivity seawater element for use in high fouling or challenging feedwater conditions, helping to support smooth operations and low cost of water.

The benefits of DOW FILMTEC SW30HRLE-370/34i elements include:

  • A wide 34 mil feed spacer to lessen the impact of fouling on pressure drop across a vessel and enhance cleaning effectiveness.
  • Guaranteed active area of 370 square feet, maximizing productivity and enabling accurate and predictable system design and operating flux.
  • Utilization of the distinct iLEC™ interlocking endcaps that help to reduce system operating costs and reduce the risk of o-ring leaks that cause poor water quality. 
  • Effective use in permeate staged seawater desalination systems without impairing the performance of the downstream stage.
  • High performance over the operating lifetime without the use of oxidative post-treatments. DOW FILMTEC elements are more durable and may be cleaned over a wider pH range (1-13) than other RO elements. 
  • Automated, precision fabrication with a greater number of shorter membrane leaves reducing the effect of overall fouling and maximizing element efficiency.

  1. The above benchmark values are based on the following test conditions: 32,000 ppm NaCl, 5 ppm Boron, 800 psi (5.5 MPa), 77°F (25°C), pH 8 and 8% recovery.
  2. Permeate flows for individual elements may vary, +/-15%.
  3. Product specifications may vary slightly as improvements are implemented.
  4. Active area guaranteed +/-5%. Active area as stated by Dow is not comparable to nominal membrane area often stated by some manufacturers. Measurement method described in Form No. 609-00434 (168KB PDF).
