DOW Filmtec BW30-2540 RO Membrane 1000 GPD, a 2.5"×40" brackish water Reverse Osmosis Membrane that can provide RO quality water up to 1,000 gallons per day at a 15% recovery rate. It can operate at feed pressures ranging from 225 psi to 600 psi with 99.5% salt rejection. This element offers the highest quality water for commercial and light industrial systems purifying less than one gallon per minute(0.2 m3/d) of RO water and is the industry standard for reliable operation and production of the highest quality water in commercial applications.

These RO elements can separate salts from water and are produced with an automated fabrication process for precision, consistency, and reliability offering high rejection of dissolved solids and organics and operate very efficiently at lower pressures. The Thin Film-Commercial RO membranes have hard shell exterior and are recommended for systems with multiple-element housings containing three or more membranes, as they are designed to withstand higher pressure drops. In addition to the highest quality water and the lowest energy costs, FILMTEC membranes also deliver savings by providing the industry’s longest lasting and most reliable performance due to increased resistance to fouling.

This membrane is a part of the "Fiberglassed Elements for Light Industrial Systems" line of products by DOW FILMTEC and are applied in commercial water treatment systems, food service, hospitality industry, medical and research institutions. Its advanced technological design is manufactured for excellent structural stability and more productivity than other elements.


Key Features and Benefits:

  • 1,000 Gallons per day.
  • 600 psi maximum operating pressure.
  • Removes chemical contaminants.
  • Reduce wastewater volumes by increasing water reuse.
  • High flux results in high yields.
  • Low energy costs with high rejection providing good water quality.
  • Hard shell exterior for extra strength.
  • Durable with Good Cleanability for Long Element Life.
  • DOW FilmTec high quality, long lasting and reliable performance.

* Permeate flow rate and salt rejection based on the following test conditions: 2000 ppm NaCl, 225 psig (15.5 bar), 77°F(25°C), 15% recovery. Permeate flow rates for individual elements may vary +/-20%.
**Maximum temperature for continuous operation above pH 10 is 95°F (35°C).
*** 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.



PRODUCT NOTES:
- Proper start-up of reverse osmosis water treatment system is essential to prepare the industrial membrane elements for operating service and to prevent membrane damage due to overfeeding or hydraulic shock.
- Before initiating system start-up procedures, membrane pre-treatment, loading of the membrane elements, instrument calibration and other system checks should be completed.
- During prolonged system shutdowns, it is recommended that the Dow Filmtec membrane elements be immersed in a preservative solution. This is to prevent biological growth.
(To ensure proper product startup and usage, please review Operation Guidelines and General Information section from the Product Data Sheet.)
