DuPont Water Solutions offers various premium Seawater Reverse Osmosis (RO) Elements designed to improve system uptime and plant reliability which ultimately translate to lower Total Cost of Ownership (TCO). FilmTec™ Elements combine premium membrane performance with automated precision fabrication, which takes system performance to exceptional levels.

FilmTec™ SW30XFR-400/34 Elements are designed specifically to handle biofouling in seawater desalination plants. Elements are equipped with advanced fouling-resistant and cleanability features, helping plants reduce the number of chemical cleanings, while maintaining high rejection and low energy. Benefits of the FilmTec™ SW30XFR-400/34 Elements include:

• Fouling-resistant design, reducing the number of chemical cleanings by more than 33%.
• Durable membrane chemistry, maintaining stable and high rejection despite repeated chemical cleanings.
• Low element differential pressure, improving system hydraulic balance.
• More effective and efficient cleaning of biofilm, organic compounds and scale, achieved through the widest pH range in cleaning (pH 1 – 13), made possible by the most advanced FilmTec™ RO membrane sheet available today.

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.
