FilmTec™ Dry Seawater Reverse Osmosis 8" Elements

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.
