DuPont FilmTec Commercial RO Membranes

DOW FilmTec Reverse Osmosis Membranes
Reverse Osmosis Membrane Elements for Tapwater and Brackish Water Commercial Applications

DOW FILMTEC offers a variety of low energy and high rejection FILMTEC reverse osmosis elements for small commercial operations such as car washes and resort applications.

  • DOW FILMTEC TW30 elements are an industry standard for reliable operation and production of high quality water. These features a 34 mil feed spacer to lessen the impact of fouling and may be cleaned over a wide pH range (pH 1-13) for the most effective cleaning.
  • DOW FILMTEC LP & XLE elements deliver high performance at low pressure resulting in less energy usage and lower costs.
  • FRP-wrapped elements are recommended for systems with multiple-element housings containing three or more membranes, as they are designed to withstand higher pressure drops.
