FilmTec™ SW30HRLE-440 Wet

FilmTec™ Seawater Reverse Osmosis 8" Elements

Wet FilmTec™ SW30HRLE-440 Element

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.
