Characteristics of Rejection SWRO Membrane 

  1. A higher sheet density significantly raises the membrane rejection rate.
  2. High rejection rate and high boron removal rate.
  3. The non-oxidation post-treatment procedure guarantees the chemical stability and longevity of membranes.
  4. Use a design with a short membrane sheet length to lower the membrane fouling rate.
  5. Improve the effective area's usage rate.
  6. Provide a more uniform flux distribution on the membrane surface.
