FilmTec™ Seawater Reverse Osmosis 8" Elements

DuPont Water Solutions offers various premium seawater reverse osmosis (RO) elements designed to reduce the capital and operating costs of desalination systems. FilmTec™ elements combine excellent membrane quality with automated precision fabrication, elevating 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 a very high active area and a thick feed spacer (28 mil) allows for 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.

Product Category

Seawater Reverse Osmosis 8" FilmTec™ 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.
