How to Choose the Right FRP Membrane Housing?

FRP membrane housing, together with RO membranes, is widely used in RO systems to remove pigments, hardness, high valence ions and other impurities in the water, so that water after treatment can meet pure water standards. You may choose the right FRP membrane housing according to the following steps to improve the working efficiency and extends the lifespan of membrane elements.

  1. Product Application
    1. When being used in land fills and landfill leachate treatment, you may choose DTRO FRP membrane housings;
    2. When being used in pure water, ultra pure water, deionized water and cooling water preparation, you may choose Winder® series and Winder®-G series FRP membrane housings.
      1. Winder® FRP membrane housing. ASME certified, and passed burst test at 6 times of design pressure and 100,000 times of cycle test;
      2. Winder®-G FRP membrane housing. Economical FRP membrane housing, and passed burst test at 4 times of design pressure and 60,000 times of cycle test.
  2. Method of Water Intake
    1. In the system, if the water enters from both ends of the membrane housing, you may choose FRP membrane housings with end port;
    2. In the system, if the water enters from both sides of the membrane housing, you may choose FRP membrane housings with side port.
  3. Feed Pressure
    1. When the system pressure falls between 300 to 450 PSI, you may choose low pressure Winder® series and Winder®-G series FRP membrane housings;
    2. When the system pressure falls between 600 to 2000 PSI, you may choose high pressure Winder® series FRP membrane housings.
  4. FRP membrane housing diameter. Commonly used FRP membrane housing diameters are 8.0", 4.0" and 2.5".
  5. FRP membrane housing length. Commonly used FRP membrane housing lengths are 14", 21" and 40".
