FilmTec XLE & ULE – Low Energy Seawater Desalination RO Membranes
DOW FILMTEC SW30XLE & SW30ULE elements offer a good combination of productivity and rejection resulting in a low energy seawater element and low operating cost. It is ideal for two-pass seawater designs and high TDS brackish water applications. DOW FILMTEC SW30XLE elements come with iLEC™ Interlocking Endcaps that reduce system operating costs and reduce the risk of o-ring leaks that cause poor water quality.

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. Permeate flows for individual elements may vary +/-15%. Product specifications may vary slightly as improvements are implemented.
