DuPont™ Water Solutions offers various premium seawater reverse osmosis (RO) elements designed to produce high quality water which may reduce capital and operation costs of desalination systems. FilmTec™ elements combine excellent membrane quality with automated precision fabrication to take system performance to exceptional levels.

FilmTec™ SW30XHR–440 elements are the highest rejection seawater RO elements in the FilmTec™ element portfolio, enabling stringent water quality requirements to be met reliably with single-pass seawater systems in most situations. In addition, the combination of highest active area and a thick feed spacer results in higher productivity and lower cleaning frequency, which enables sustainable lower life-cycle cost. Benefits of the FilmTec™ SW30XHR–440 element include:

• Highest NaCl and boron rejection to help meet World Health Organization (WHO) and  other drinking water standards more cost effectively.
• The highest guaranteed active area of 440 ft2 (41 m2) permits lowest system cost by maximizing productivity and enables accurate and predictable system design and operating flux.
• The combination of highest active area with a thick feed spacer (28 mil) allows low cleaning frequency and high cleaning efficiency.
• Sustainable high performance over the operating lifetime, 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.
