Dow Filmtec SW30HRLE-400i Reverse Osmosis (RO) Membrane
replacement 7,500 GPD seawater desalination reverse osmosis (RO) membrane element
The Filmtec SW30HR LE-400i element offers a combination of high rejection and low energy requirements to allow lower total costs with medium and high salinity feedwater. Filmtec SW30HR LE-400i element comes with the distinct iLEC(tm) Interlocking Endcaps that help reduce system operating costs and reduce the risk of o-ring leaks that cause poor water quality. Benefits of the Filmtec SW30HR LE-400i element include:
- Enables systems to be designed and operated to optimize operating cost through lower energy consumption or to optimize 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.
- 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. This is one reason Filmtec elements are more durable and may be cleaned more effectively 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, helping to lower your cost of operation.

*The above benchmark values are based on the following test conditions: 32,000 ppm NaCl, 800 psi (5.5 MPa), 77F (25C), pH 8 and 8% recovery. Permeate flows for individual elements may vary +/-15%.
**Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Since oxidation damage is not covered under warranty, Dow recommends removing residual free chlorine by pretreatment prior to membrane exposure. Most RO systems have carbon pre-filters for this purpose.
***Maximum temperature for continuous operation above pH 10 is 95F (35C).
Note: Active surface area guaranteed +/-5%. Active area as stated by FilmTec is not comparable to nominal membrane area often stated by some manufacturers.
