Spiral Membrane

MS spiral membrane modules are composed of a combination of PVDF flat membrane sheets separated by a thin meshed spacer material which serves as a porous plastic screen support. These sheets are rolled around a central perforated tube and fitted into a tubular steel pressure vessel casing. The feed solution passes over the membrane surface and the permeate spirals into the central collection tube. MS spiral membrane modules offer a high volumetric throughput and can also be easily cleaned.


  • Designed with high intensity.
  • With wide port design, less fouling.
  • High pressure resistance.
  • High cleaning recoverability.
  • High chemical resistance.
  • Simple structure, reasonable design, easy to tear open outfit.


  • Process and drinking water.
  • Pharmaceuticals and medical products.
  • Biotechnology.
  • Food and beverage.
  • Enzyme preparation.
