FilmTec™ Dry Seawater Reverse Osmosis 8" Elements


FilmTec™ SW30XFR-400/34 Dry


DuPont Water Solutions offers various premium Seawater Reverse Osmosis (RO) Elements designed to improve system uptime and plant reliability which ultimately translate to lower Total Cost of Ownership (TCO). FilmTec™ Elements combine premium membrane performance with automated precision fabrication, which takes system performance to exceptional levels.

FilmTec™ SW30XFR-400/34 Elements are designed specifically to handle biofouling in seawater desalination plants. Elements are equipped with advanced fouling-resistant and cleanability features, helping plants reduce the number of chemical cleanings, while maintaining high rejection and low energy. Benefits of the FilmTec™ SW30XFR-400/34 Elements include:

  • Fouling-resistant design, reducing the number of chemical cleanings by more than 33%.
  • Durable membrane chemistry, maintaining stable and high rejection despite repeated chemical cleanings.
  • Low element differential pressure, improving system hydraulic balance.
  • More effective and efficient cleaning of biofilm, organic compounds and scale, achieved through the widest pH range in cleaning (pH 1 – 13), made possible by the most advanced FilmTec™ RO membrane sheet available today.

Starting in 2020, DuPont Water Solutions has produced and supplied our customers dry seawater reverse osmosis FilmTec™ elements. As an industry leader, we will be the first supplier to offer dry-tested SWRO elements.

  • Dry elements do not have expiration date, making easier warehouse maintenance and inventory planning.
  • Dry elements do not need re-preservation while wet elements preservation solution needs to be checked after 12 months of storage and eventually replaced. This operation is very labor intensive and can lead to high costs.
  • More attractive warranties. The allowable storage time before mandatory start of the warranty has been extended by 6 months.
  • Dry elements are lighter (4 kg / 8 pounds less) and do not have a preservation solution, which involves an easier and safer loading and installation.
  • Due to the lower weight and the lower energy and water consumed during testing, dry elements are more environmentally friendly compared to wet elements, more specifically dry elements represent a 20% reduction in CO2 emissions compared to wet elements.
