FilmTec™ Seawater Reverse Osmosis 8" Elements

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.

Product Category

FilmTec™ Seawater Reverse Osmosis 8" Elements can separate salts from water and are designed to reduce capital and operational costs of large desalination systems that produce greater than approximately 10 gpm (2300 L/h) of permeate. With a wide range of membranes available to meet various system design requirements, our RO products combine excellent membrane quality with automated precision fabrication, taking system performance to unprecedented levels.
