FILMTEC SW30XLE-400i Membrane Elements

FilmTec offers various premium seawater reverse osmosis (RO) elements to reduce capital and operation cost of seawater RO systems. FILMTEC products combine premium membrane performance with automated precision fabrication and maximize system output to unprecedented performance.

FILMTEC SW30XLE-400i offers an unequalled combination of productivity and rejection. This is the lowest energy seawater element available on the market, enabling lowest operation cost. It is also ideal for two-pass seawater designs and high TDS brackish water applications. FILMTEC SW30XLE-400i comes with the unique iLEC™Interlocking Endcaps that reduce system operating costs and reduce the risk of o-ring leaks that cause poor water quality. See Form No.609-00446 (396KB PDF) for information on the trouble-free cost-saving benefits of iLEC Interlocking Endcaps. Benefits of SW30XLE-400i include:

Highest productivity available, with active area of 400 sq. ft., enables systems to be designed to deliver the lowest total cost of water by optimizing energy consumption, system productivity and operating flux.
Can effectively be used in permeate staged seawater desalination systems without impairing the performance of the downstream stage.
Delivers high performance over the operating lifetime without the use of oxidative post-treatments like many competitive products. This is one reason FILMTEC elements are more durable and may be cleaned more effectively over a wider pH range (1-13) than other RO elements.
Automated, precision fabrication with a greater number of shorter membrane leaves reduces the effect of overall fouling and maximizes element efficiency, lowering your cost of operation.

Virtually Eliminate O-ring Leakage and Lower Your Energy Costs

Select FILMTEC™ brackish water and seawater reverse osmosis (RO) elements are now commercially available with iLEC™ interlocking endcaps, an innovative element coupling technology that significantly enhances the performance of RO systems.

Unlike sliding couplers, the decades-old connection method still used in most of today's advanced RO systems, the iLEC technology achieves a direct, leak-tight connection between adjacent element permeate tubes, reducing the number of sealing surfaces to a single, axially compressed o-ring. This patented design dramatically reduces the potential for seal leakage, enabling sustained higher quality permeate throughout the life of the elements, and reduces energy-consuming flow resistance, resulting in lower operating costs.

1. The above 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.
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 FilmTec is not comparable to the nominal membrane area figure often stated by some element suppliers. Measurement method described in Form No.609-00434

5. Stabilized Boron Rejection - 88%.
