DOW FilmTec Membrane Elements

DOW FILMTEC™ SW30HRLE-400 High Rejection High Flux Seawater Desalination RO Elements

DOW FILMTEC SW30HRLE-400 Elements offer rejection and low total cost of water for seawater desalination. The FILMTEC SW30HRLE-400 delivers high performance over the operating lifetime without the use of oxidative post-treatments and provides high NaCl and boron rejection to help meet World Health Organization (WHO) and other drinking water standards.

DOW FILMTEC Seawater Reverse Osmosis 8" Elements separate salts from water and are designed to reduce capital and operational costs of large desalination systems that produce greater than approximately 10 gpm (2300 L/h) of permeate. FilmTec Seawater RO products combine excellent membrane quality with automated precision fabrication, taking system performance to unprecedented levels.

Each element is supplied with one coupler (part number PV-IN810S, 313198) for interconnecting multiple membranes end-to-end in a membrane housing.  Each coupler includes two 3-912 EPR O-rings.

DOW FILMTEC SW30HRLE-400 is FDA – 21 CFR 177.2550; Food and Drug Administration Compliant.
