Dow Filmtec SW30HRLE-4040 Reverse Osmosis (RO) Membrane
replacement 1,600 GPD seawater desalination reverse osmosis (RO) membrane element
Filmtec SW30HR LE-4040 reverse osmosis element is a four-inch diameter version of SW30HR LE-400, the industry's leading seawater element which offers an unprecedented combination of high salt rejection and productivity to enable the lowest total cost of purifying high salinity water.
- SW30HR LE-4040 may be used as a pilot element to demonstrate performance for the design of larger systems.
- SW30HR LE-4040 delivers the highest sodium chloride and boron rejection to help meet World Health Organization (WHO) and other drinking water standards.
- SW30HR LE-4040 elements deliver high performance over the operating lifetime without the use of oxidative post-treatments like many competitive products. 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.

*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 +/-20%.
**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.
