DuPont Water Solutions offers various premium seawater reverse osmosis (RO) elements designed to help reduce capital and operation cost of desalination systems. FilmTec™ Elements combine excellent membrane quality with automated precision fabrication, taking system performance to exceptional levels.

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. Benefits of the FilmTec™ SW30HRLE–440 Element include:

• Helps systems to be designed and operated to either lower operating cost through reduced energy consumption, or to decrease capital cost through higher productivity at lower operating fluxes.
• High NaCl and boron rejection to help meet World Health Organization (WHO) and other drinking water standards.
• Very high guaranteed active area of 440 ft2 (41 m2) permits lower system cost by maximizing productivity and facilitating accurate and predictable system design and operating flux.
• The combination of very high active area with a thick feed spacer (28 mil) allows low cleaning frequency and high cleaning efficiency.
• Sustainable high performance over the operating lifetime of the element, because oxidative treatments are not used in membrane production. This is one reason FilmTec™ elements are more durable and may be cleaned more effectively over a wider pH range (1 – 13) than most other RO elements, which use oxidative treatments.
• Effective use in permeate staged seawater desalination systems without impairing the performance of the downstream stage.
