Dow Filmtec SW30HR-380 Reverse Osmosis (RO) Membrane

replacement 6,000 GPD seawater desalination reverse osmosis (RO) membrane element

The Filmtec SW30HR-380 is a premium grade seawater reverse osmosis element featuring both high active area and high salt rejection to offer the best long-term economics for seawater desalination systems.

  • Filmtec SW30HR-380 delivers the highest boron rejection to help customers meet World Health Organization (WHO) and other drinking water standards.
  • Filmtec SW30HR-380 elements deliver high performance over their operating lifetime without the use of oxidative post-treatments like many competitive products. This is one reason why Filmtec elements are more durable and may be cleaned more effectively over a wide pH range than other RO elements.
  • Automated, precision fabrication with a greater number of shorter membrane leaves, reduces the overall effect of fouling and maximizes membrane efficiency.

*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).Operation at pressures up to 1,200 psig (83 bar) is allowable under certain conditions. Consult your Dow representative for advice on applications above 1,000 psig (69 bar).

Note: Active surface area guaranteed +/-5%. Active area as stated by FilmTec is not comparable to nominal membrane area often stated by some manufacturers.
