DuPont FilmTec SW30XLE-400 RO Membrane

For medium and high salinity water, the DuPont FilmTec SW30XLE 400 (USA) Dry Element is a cost-effective choice throughout its lifespan. The element achieves this by removing a high percentage of impurities while using less energy, thanks to its large filtering area and a special spacer that optimizes water flow.

  • High flux reduces energy use or pressure required
  • Good rejection results in good quality water
  • High boron rejection

Applications

  • Seawater desalination
  • Municipal drinking water
  • Industrial desalination plants

Description

FilmTec 8″ Seawater Low Energy Reverse Osmosis Membranes

DuPont offers SW30XLE-400 Dry-tested seawater reverse osmosis elements to give customers the flexibility that comes with increased ability for storage and the operational and safety benefits related to its lower weight and the absence of preservation solution. For years, innovation in the SWRO space has been focused on incremental improvement of product specifications. The ability to transition from wet testing to dry testing seawater membranes is one of the biggest breakthroughs in the water filtration industry in many years. This innovation beyond product specifications has been enabled thanks to continuous advancements in membrane chemistry, automated precision and consistent manufacturing, single source production and enhancements in testing methods and procedures.

Key Features

  • Delivers low total cost of water by optimizing energy consumption and system productivity.
  • Excellent durability resulting in stable long-term performance.
  • Longer storage time and warranty coverage with improved sustainability footprint versus our wet RO membrane elements.

FilmTec SW30XLE-400 Specifications

  • 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.
  • 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.

Key Applications

  • Seawater desalination for municipal and industrial installations
  • Suitable for medium and high feed water salinity
