Membranes

The heart of an industrial membrane application is always the membrane. Hence you are in good hands at GMT. Our core competence is the reliable industrial manufacturing of composite membranes. These membranes are made up of a nonwoven support structure, a microporous polymeric support layer and an extremely thin nonporous selective separation layer. These layers must be balanced in an optimised way to achieve the expected separation properties. Furthermore, this structure offers a highly flexible membrane design, as different selective separation layers can be combined with different support layers. Such optimised membranes are successfully used in gas separation as well as organophilic nanofiltration.

The manufacturing of different composite membranes on industrial scale has led to a solid know-how base regarding the product area of ultrafiltration membranes. This know-how is a basic requirement of successful composite membranes, as only a precisely defined support layer enables the manufacturing of high performance composite membranes. Consequently, we can also offer you excellent ultrafiltration membranes.

Our membrane portfolio includes:

  • Membranes for gas separation
  • Membranes for organophilic nanofiltration
  • Ultrafiltration membranes for the treatment of organic and organic-aqueous liquids
