Pure Aqua has over 20 years of experience as a global provider of Dupont/DOW FilmTec Seawater Reverse Osmosis 4" Membrane Elements can divide contaminants from water, such as salt and total dissolved solids through automated manufacturing process that guarantee accuracy, reliability, and consistency.

DOW FILMTEC seawater membrane delivers high boron rejection to help customers meet World Health Organization (WHO) and other drinking water standards. FILMTEC seawater reverse osmosis membrane elements deliver high performance over their operating lifetime without the use of oxidative post-treatments like many competitive products. This is one reason why FILMTEC seawater membrane are more durable and may be cleaned more effectively over a wider pH range (1-13) than other RO elements. The DOW FILMTEC elements is a premium grade seawater reverse osmosis element featuring both high active area and high salt rejection to offer the best long-term economics for seawater desalination systems.

Thin-Film Composite (TFC Membrane) design

FilmTec thin-film composite membranes (TFC membranes) are the world’s leading RO membrane for water purification systems. To date, more than 1,000,000 FilmTec membranes have been installed in water treatment systems worldwide.

FILMTEC seawater membrane is a durable, high-rejection, high-productivity seawater element for use in high fouling or challenging feedwater conditions, helping to support smooth operations and low cost of water.

FILMTEC™ Seawater membranes are capable of separating saline from water and are manufactured through an automatic fabrication procedure that assures accuracy, dependability and stability. They are most suitable for smaller sized desalination plants that produce less than 12 gallons per minute of permeate. Filmtec seawater membrane consist of one of the largest flow rates in the market and are able to handle the water requirements of both land-based and sea-based desalinators. These membrane elements can also function at low pressures to cut the cost of operating, pumps, and system expenses.

Filmtec seawater membranes are viewed as the industry’s leading reverse osmosis elements and provide an unmatched mixture of efficiency and high salt rejection to effectively lower the overall cost of treating salt water. Filmtec elements offer long life value with incredible performance without the use of pre-chlorination or post-treatment to meet freshwater standards.
