WaterSolutions DOW FILMTEC SW30HRLE-400

DOW™ FILMTEC™ SW30HRLE-400 element offers very high productivity and rejection, enabling the low total cost of water for seawater desalination. Benefits of DOW FILMTEC SW30HRLE-400 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.
Can effectively be used 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 like many competitive products. This is one reason DOW 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 reduces the effect of overall fouling and maximizes element efficiency, lowering cost of operation.

Nominal Active Surface Area ft² (m²)	Permeate Flow Rate gpd (m³/d)	Stabilized Salt Rejection (%)	Minimum Salt Rejection (%)	Stabilized Boron Rejection (%)
400 (37)	7,500 (28)	99.80	99.65	92

The above values are normalized to the following test conditions: 32,000 ppm NaCl, 5 ppm Boron, 800 psi (5.5 MPa), 77°F (25°C), pH 8 and 8% recovery.
Permeate flows for individual elements may vary +/-15%.
Sales specifications may vary as design revisions take place.
Active area guaranteed +/-5%. Active area as stated by Dow is not comparable to nominal membrane area often stated by some manufacturers. Measurement method described in Form No. 609-00434 (168KB PDF).
Stabilized Boron Rejection - 91%.
