FilmTec™ Seawater Reverse Osmosis 8" Elements


FilmTec™ SW30XHR-400


DuPont Water Solutions offers various premium seawater reverse osmosis (RO) elements designed to produce high quality water which may reduce capital and operation cost of seawater RO systems. These products combine premium membrane performance with automated precision fabrication to provide reliable and consistent performance.

FilmTec™ SW30XHR–400 Elements are the highest rejection seawater RO elements in the FilmTec™ Element portfolio, enabling stringent water quality requirements to be met with single-pass seawater systems in most situations. Benefits of the FilmTec™ SW30XHR–400 Element include:

  • Very high NaCl and boron rejection to help meet World Health Organization (WHO) and other drinking water standards more cost effectively.
  • Guaranteed active area of 400 ft² maximizes productivity and enables accurate and predictable system design and operating flux.
  • Effective use in permeate staged seawater desalination systems without impairing the performance of the downstream stage.
  • High performance over the operating lifetime without the use of oxidative post-treatments. FilmTec™ Elements are more durable and may be cleaned over a wider pH range (1 – 13) than other RO elements.
  • Automated, precision fabrication with a greater number of shorter membrane leaves reducing the effect of overall fouling and maximizing element efficiency.
