Dow Filmtec Membrane BW30-400

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.
