DOW FilmTec Membranes
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.

Benefits of FilmTec Tap and Brackish Water Commercial 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.
  • LP & XLE elements reduce operating costs due to lower energy requirements.
  • TW30 elements provide longer life due to increased resistance to fouling.
