The Dow Chemical Company recently sent a discontinuation notice for the FILMTEC BW30LE-440 and BW30LE-4040 which have been an industry standard for many years. Dow will not take orders for the current LE elements after May 30, but will honor any orders on the books even if shipment is not until the end of the year.
The good news is FilmTec Corporation has developed a new Low Energy, LE, membrane. FILMTEC elements rolled from this LE membrane have the highest active membrane areas, and operate at lower pressure reducing operating costs.
FILMTEC LE-440i:This RO membrane element replaces the FILMTEC BW30LE-4040 RO Element. The FILMTEC LE-440
i has 440 square feet of RO membrane which is the highest active membrane area in the industry.
The FILMTEC LE-440
i element:
Has 10% higher productivity than the FILMTEC BW30LE-4040
Operates at lower pressure
Maintains High Rejection
Minimizes operating expense
Reduces total cost to produce industrial, commercial, or municipal water
Incorporates iLECTM interlocking endcaps minimizes O-ring leaks which improves permeate quality
FILMTEC< LE-400 element:
This RO membrane element replaces the FILMTEC BW30LE-440 RO Element. The FILMTEC LE-400 has 400 square feet of RO membrane.
The FILMTEC LE-400i element:
Has higher salt rejection for better permeate quality
Operates at lower pressure
Minimizes operating expense
Reduces energy cost to produce industrial, commercial, or municipal water
