FILMTEC SW30HR-370/34i
Dow Water Solutions offers various premium seawater reverse osmosis (RO) elements designed to produce high quality water and 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™ SW30HR-370/34i element is a durable, high-rejection, high-productivity seawater element for use in high fouling or challenging feedwater conditions, helping to support smooth operations and low cost of water.
The benefits of FILMTEC SW30HR-370/34i elements include:
-
A wide 34 mil feed spacer to lessen the impact of fouling on pressure drop across a vessel and enhance cleaning effectiveness.
-
Guaranteed active area of 370 square feet maximizing productivity and enabling accurate and predictable system design and operating flux.
-
Utilization of the distinct iLEC™ interlocking endcaps that help to reduce system operating costs and reduce the risk of o-ring leaks that cause poor water quality.
-
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.

1. The above benchmark values are based on the following test conditions: 32,000 ppm NaCl, 5 ppm Boron, 800 psi (5.5 MPa), 77°F (25°C), pH 8, 8% recovery.
2. Permeate flows for individual elements may vary +/-15%.
3. Product specifications may vary slightly as improvements are implemented.
4. Active area guaranteed +/-5%. Active area as stated by FilmTec Corporation is not comparable to the nominal membrane area figure often stated by some element suppliers. Measurement method described in Form No. 609-00434 (4223KB PDF).
