FILMTEC LE-440i Membrane Elements
The FILMTECTM LE-440i element is a low-energy element featuring the highest active membrane area in the industry. It enables high productivity and low energy operation, while maintaining high-rejection performance, minimizing operating expense and lowering the total cost of water for industrial and municipal applications.
-
Delivers the same permeate flow at an equivalent operating flux at 40% lower feed pressure, compared to the FILMTEC BW30-440i element.
-
Offers permeate flow rate 10 percent higher while producing similar permeate quality than that of the FILMTEC LE-400 element, enabling the lowest total cost of water in high-purity industrial applications.
-
Includes iLEC™ interlocking endcaps, which reduce system operating costs and the risk of o-ring leaks that cause poor water quality.
-
Designed using an industry standard 1.125 inch ID permeate tube for interchangeability with other brackish water elements.

1. Permeate flow and salt rejection based on the following test conditions: 2000 ppm NaCl, 150 psi (10.3 bar), 77°F (25°C), pH 8, and 15% recovery.
2. For comparison, the LE-440i will have a permeate flow of 13,400 gpd (51 m3/d) and stabilized salt rejection of 99.3% when normalized to a feed solution of 1500 ppm NaCl as used by some manufacturers.
3. Flow rates for individual elements may vary but will be no more than 15% below the value shown.
4. Sales specifications may vary as design revisions take place.
5. Active area guaranteed +/-3%. Active area as stated by FilmTec is not comparable to nominal membrane area often stated by some manufacturers. Measurement method described in Form No.609-00434
