DOW FILMTEC™ Brackish Water Reverse Osmosis Membrane 8" Elements

DOW FILMTEC™ Brackish Water Reverse Osmosis Membranes are 8" Elements that can separate salts from water and are produced with an automated fabrication process that ensures long life, precision, consistency, and reliability. They are ideal for use in large-scale industrial and municipal RO system used for water treatment systems that produce greater than approximately 10 gpm (2300 L/h) of permeate. Our high efficiency RO membranes build on a tradition of leadership in the thin-film composite membrane filtration industry and meet today's challenges for higher rejection using less energy and resisting fouling in challenging waters.
