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™ SW30-4040

FILMTEC™ SW30-4040 Elements have one of the highest flow rates available to provide the highest productivity while maintaining excellent salt rejection to meet the water demands of both sea-based and land-based desalinators. FILMTEC SW30-4040 elements may also be operated at lower pressure to reduce pump size, cost, and operating expenses.  fully automated and precise element production enables the most consistent products in the industry for the most consistent product performance available.
