DOW FilmTec Membranes

FilmTec Fiberglassed Commercial RO Membrane Elements for Challenging Water Conditions

DuPont FilmTec (formerly 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.  FilmTec brackish water elements feature the fouling resistance membrane chemistry (made in USA) and thicker feed spacer to lessen the impact of fouling in harsh water conditions as well as a fiberglassed shell, which is recommended for systems with multiple-element housings containing three or more membranes, as they are designed to withstand higher pressure drops. For the most effective cleaning, the element may be cleaned over a wide pH range (pH 1 – 13).

Benefits of FilmTec Commercial Reverse Osmosis Membrane Elements

  • Reverse Osmosis removes up to 99.7% of total dissolved solids.
  • RO membranes remove dissolved impurities such as chloride, lead, chromate, fluoride, bacteria, and others. Click here to view the nominal rejection characteristics of thin film membranes.
  • Hard-Shell FRP Wrap allows elements to withstand higher pressure drops, making them ideal for systems with multiple elements per housing
  • BW30 elements provide longer life due to increased resistance to fouling and high cleanability.
  • LC LE elements reduce operating costs due to lower energy requirements.
