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-440i Elements offers sustainable lower lifecycle cost for medium- and high-salinity feedwaters with high stabilized salt rejection of 99.80% and high boron rejection. The highest guaranteed active area of 440 ft2 (41 m2) permits lowest system cost by maximizing productivity and enables accurate and predicable system design. A 28-mil feed spacer provides low cleaning frequency and high cleaning efficiency. iLEC™ Interlocking End Caps reduce system operating costs and the risk of o-ring leaks that can cause poor water quality.

FilmTec™ Dry Seawater Reverse Osmosis 8" Elements

 
 
 

We’re proud to offer dry-tested reverse osmosis elements to give our 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 & consistent manufacturing, single source production and enhancements in testing methods and procedures.
