FILMTEC™ brackish water reverse osmosis membrane elements provide consistent system performance in light industrial applications.
  • Filmtec™ BW30-4040 is an industry standard for reliable operation and production of high quality water. 
  • Filmtec™ BW30-2540 elements are designed for systems smaller than 1 gpm (0.2 m3 /h) offering a hard shell exterior for extra strength.
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.

Important Information:
  • Proper start-up of reverse osmosis water treatment systems is essential to prepare the membranes for operating service and to prevent membrane damage due to overfeeding or hydraulic shock. Following the proper start-up sequence also helps ensure that system operating parameters conform to design specifications so that system water quality and productivity goals can be achieved. 
  • Before initiating system start-up procedures, membrane pretreatment, loading of the membrane elements, instrument calibration and other system checks should be completed. 
  • Please refer to the application information literature entitled “Start-Up Sequence” (Form No. 609-02077) for more information.

Operation Guidelines:
Avoid any abrupt pressure or cross-flow variations on the spiral elements during start-up, shutdown, cleaning or other sequences to prevent possible membrane damage. During start-up, a gradual change from a standstill to operating state is recommended as follows:
  • Feed pressure should be increased gradually over a 30-60 second time frame. 
  • Cross-flow velocity at set operating point should be achieved gradually over 15-20 seconds. 
  • Permeate obtained from first hour of operation should be discarded.
Please refer to the product technical manual.

General Information:
  • Keep elements moist at all times after initial wetting 
  • If operating limits and guidelines given in this bulletin are not strictly followed, the limited warranty will be null and void. Refer to FILMTEC™ Reverse Osmosis and Nanofiltration Element Three-Year Prorated Limited Warranty (Form No. 609-35010)
  • To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution
  • The customer is fully responsible for the effects of incompatible chemicals and lubricants on elements 
  • Maximum pressure drop across an entire pressure vessel (housing) is 50 psi (3.4 bar) 
  • Avoid static permeate-side backpressure at all times
