  • How to Install DOW Filmtec Commercial Reverse Osmosis Membranes:
    After installation of the Filmtec XLE-4021, the first full tank of permeate should be discarded. Do not use this initial permeate.
    Proper start-up of reverse osmosis water treatment system is essential to prepare the XLE-4021 industrial membrane elements for operating service and to prevent membrane damage due to overfeeding or hydraulic shock.
    Keep the XLE-4021 RO element moist at all times after initial wetting.
    During prolonged system shutdowns, it is recommended that the Filmtec Dow XLE-4021 membrane elements be immersed in a preservative solution. This is to prevent biological growth.
