Other DOW FILMTEC Membranes

FilmTec elements from Dow feature a spiral wound design and are based on the FT30 thin-film composite polyamide membrane, which has long been the industry standard for RO performance. The FilmTec FT30 membrane consists of three layers: an ultra-thin polyamide barrier layer, a microporous polysulfone interlayer, and a high-strength polyester support web. The FT30 membrane has been continuously updated and refined to provide higher rejection, improved membrane flux, and low fouling performance. Today's FT30 membrane is uniquely uniform in performance and quality, without the taped or glued defects that can cause other membranes to fail. Good understanding and execution of the basics of reverse osmosis can minimize troublesome and costly problems in the future.

Over the past four decades, developments in technology have allowed Dupont/Dow Filmtec membranes to efficiently separate and isolate saline and other pollutants and particulates at the molecular level from water, allowing to convert seawater, low-quality wastewater and water flow into high-quality treated water.

Thin-Film Composite (TFC Membrane) design
The TFC membrane consists of three layers: a polyester support web, a microporous polysulfone interlayer, and an ultrathin barrier coating on the top surface.

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.
