FilmTec™ Dry Seawater Reverse Osmosis 8" Elements
FilmTec™ SW30HRLE-440 Dry Element
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.
FilmTec™ SW30HRLE–440 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.
Uses
- Seawater desalination for municipal or industrial purposes
- Direct lithium extraction
