FILMTEC MEMBRANE ELEMENTS
| FILMTEC BW30-4040 Membrane Element |
FILMTECTM brackish water reverse osmosis membrane elements provide consistent, outstanding system performance in light industrial applications.
- FILMTEC BW30-4040 is the industry standard for reliable operation and production of the highest quality water.
Elements with a hard shell exterior are recommended for systems with multiple-element housings containing three or more membranes, as they are designed to withstand higher pressure drops.

- Permeate flow rate and salt rejection based on the following test conditions: 2000 ppm NaCl, 225 psig (15.5 bar), 77°F (25°C), and 15% recovery.
- Permeate flow rates for individual elements may vary +/-20%.
- For the purpose of improvement, specifications may be updated periodically.

| FILMTEC TW30-4040 Membrane Elements |
A complete range of FILMTEC™ 4040-size elements is available to meet a wide variety of customer needs for commercial applications, from the highest purity water to the lowest total system costs..
- FILMTEC TW30-4040 is the industry standard for reliable operation and production of the highest quality water.
Tape-wrapped elements are built with the same high quality membranes and materials of construction as industrial elements, except for the hard outershell, and are more economical for commercial systems with one or two elements per housing.
