FILMTEC™ Brackish Water Reverse Osmosis < 4" Elements

FILMTEC™ Brackish Water Reverse Osmosis < 4" Elements can separate salts from water and are produced with an automated fabrication process for precision, consistency, and reliability. They are ideal for use in small-sized water treatment systems that produce less than approximately 1 gpm (230 L/h) of permeate. Our RO membranes build on a tradition of leadership in the thin-film composite membrane industry and meet the challenges of higher rejection in lower-pressure operations.

FILMTEC™ BW30-2540

FILMTEC™ BW30-2540 Elements are an industry standard for reliable operation and production of high quality water. They are designed for systems smaller than 1 gpm (0.2 m3/h). DOW FILMTEC BW30-2540 elements offer a hard shell exterior for extra strength and may be cleaned over a wide pH range (pH 1 – 13) for the most effective cleaning.
