DOW FILMTEC™ SW30HR LE-4040 Seawater RO Elements for Watermakers and Marine Systems

DOW FILMTEC SW30HRLE-4040 Elements are the 4-inch diameter version of DOW FILMTEC SW30HRLE-400, one of the industry's leading seawater elements, which offers an unprecedented combination of high salt rejection and productivity to enable the low total cost of purifying high salinity water. DOW FILMTEC SW30HRLE-4040 elements deliver high performance over the operating lifetime without the use of oxidative post-treatements and high sodium chloride and boron rejection to help meet World Health Organization (WHO) and other drinking water standards. DOW FILMTEC SW30HRLE-4040 may be used as a pilot element to demonstrate performance for the design of larger systems.

DOW FILMTEC SW30HR LE-4040 is FDA – 21 CFR 177.2550; Food and Drug Administration Compliant.
