FILMTEC BW30-400 Membrane Elements
The FILMTECTM BW30-400 element is the product of choice when the highest quality permeate is required. It was the first 400 square foot membrane elements on the market and continues to be widely used in new equipment and retrofits where system capital and productivity are factors.
FilmTec's superior automated manufacturing technology results in the most consistent performance element-to-element and year-after-year.
BW30-400 elements deliver high flow and high rejection without being chlorinated during the manufacturing process. This is one reason why FILMTEC elements are more durable and may be cleaned over a wider pH range (pH 1 - 13) than other RO elements.
With more than a decade of proven performance, BW30-400 is the product you can rely on for years of trouble-free operation.
Nominal Active Surface Area
Permeate Flow Rate
Stabilized Salt Rejection
Minimum Salt Rejection
1. Permeate flow and salt rejection based on the following test conditions: 2000 ppm NaCl, 225 psi (15.5 bar), 77°F (25°C), pH 8, and 15% recovery.
2. Flow rates for individual elements may vary but will be no more than 15% below the value shown.
3. Sales specifications may vary as design revisions take place.
4. 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 (4223KB PDF).
