FILMTEC™ Seawater Reverse Osmosis 4" Elements

FILMTEC™ Seawater Reverse Osmosis 4" Elements can separate salts from water and are produced with an automated fabrication process that ensures precision, consistency, and reliability. They are ideal for use in medium-sized desalination systems that produce less than approximately 10 gpm (2300 L/h) of permeate.


FILMTEC™ SW30HRLE-4040 Elements are the 4-inch diameter version of 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. 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. FILMTEC SW30HRLE-4040 may be used as a pilot element to demonstrate performance for the design of larger systems.
