FILMTEC™ SW30ULE-440i

DOW™ FILMTEC™ SW30ULE-440i is an element of choice for low to medium salinity and temperature waters, for permeate staged systems for stringent water quality targets, and for high feed salinity brackish water applications. It has the highest sustainable flow rate available in the industry, coupled with high rejection of NaCl and boron. This performance can lead to significant capital and operation cost savings, especially when this element is mixed with other element types in the same pressure vessel, using the “internally staged design” approach. In addition, the combination of highest active area and thickest feed spacer of the Dow FILMTEC membranes results in higher productivity and lower cleaning frequency enabling sustainable lower lifecycle cost.

  1. The above values are normalized to the following conditions: 32,000 ppm NaCl, 800 psi (5.5 MPa), 77°F (25°C), pH 8 and 8% recovery.
  2. Permeate flows for individual elements may vary +/-15%.
  3. Product specifications may vary slightly as improvements are implemented.
