DOW FILMTEC™ BW30XFR-400/34i

DOW FILMTEC™ BW30XFR-400/34i has an optimized design and materials of construction to create a durable, high rejection and high productivity element to purify waters with biological and organic fouling tendencies. Incorporating Dow's innovative and proprietary BW30XFR membrane sheet with advanced organic fouling resistance and cleanability, this reverse osmosis (RO) element combines the best features of fouling resistance and durability, with the cleanability of an optimized 34 mil feed spacer, to improve cleaning effectiveness. All this while delivering high element performance over the life of the spiral wound brackish water RO element.

• Effective and efficient cleaning of biofilm, organic compounds and scale, achieved through the widest pH cleaning range (pH 1 – 13), made possible by the most advanced DOW FILMTEC™ RO membrane sheet available today.
• Produces 10 percent more water compared to the BW30-400/34i or BW30-400/34i FR element at the same operating pressure and higher rejection, enabling lower capital expense for new systems, or increased water production in an existing system.
• Enhanced cleaning effectiveness, reducing the impact of fouling and through the use of an optimized 34 mil feed spacer.
• Reliable system integrity, resulting in reduced system operating costs with the iLEC™ technology (interlocking end-caps), minimizing the risk of o-ring leaks that can contribute to poor water quality.
