FilmTec SW30HRLE-440 Seawater RO Membrane

Seawater High Permeate Quality Reverse Osmosis Membrane Element with Higher Productivity.
FilmTec SW30HRLE-440 RO membranes provide a convenient solution for seawater desalination plants with it’s dry-tested designs. This RO elements are need for storage in preservation solution, offering benefits related to its longer storage time, lighter weight, and improved safety.

  • Longer life-time
  • More sustainable
  • High flux reduces energy use or pressure required
  • High salt rejection results in good quality water
  • High boron rejection


FilmTec SW30HRLE-440 RO Membrane Elements  offer sustainable lower life-cycle cost for medium and high salinity feedwater by combining high rejection and low energy performance with the highest active area and a thick feed spacer.

Key Features

  • Optimized combination of water production and permeate quality.
  • Permits low system capital cost by maximizing production capacity.
  • Excellent durability resulting in stable, long-term performance.
  • Longer storage time and improved sustainability footprint versus our wet RO membrane elements.

Key Applications

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

FilmTec SW30HRLE-440 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.
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.
