Product Description
Original DOW Filmtec RO Membrane from USA

DOW FILMTEC™ brackish water reverse osmosis membrane elements provide consistent, outstanding system performance in light industrial applications. 


BW30-400 elements deliver high flow and high rejection without being chlorinated during the manufacturing process. This is one reason why DOW 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.
