This firm announces two new FilmTec 8-in. saltwater reverse osmosis (SWRO) membrane elements for improved performance and energy efficiency in desalination applications. At 99.80%, the FilmTec SW30XHR-400i has the highest salt rejection consistently demonstrated in the industry, according to the firm. It features a guaranteed active area of 400 ft 2 and flowrate of 6,000 gal/d. FilmTec SW30ULE-400i elements have a flowrate of 11,000 gal/d with 99.70% salt rejection. Both FilmTec SW30XHR-400i and SW30ULE-400i are offered with iLEC interlocking caps that reduce pressure drop within the permeate tube and help eliminate the O-ring damage that can be a cause of major leakage in traditional desalination membrane systems. — Dow Water Solutions, Edina, Minn.
