What is ion exchange membrane

An ion exchange membrane is a semi-permeable membrane that allows only certain dissolved ions to pass. The other particles such as other ions or neutral molecules are blocked. This basic feature of ion exchange membranes for selectivity to the transport of ions of opposite charges is called ion permselectivity.

Anion exchange membrane vs cation exchange membrane

Due to its ionic permselectivity the ion exchange membranes are classified into cation exchange membranes and anion exchange membranes.

Bipolar membrane

Bipolar membranes consist of a cation exchange and an anion exchange membrane laminated together.

Custom manufacturing allows customization

MEGA is one of few world's manufacturers of heterogeneous ion-exchange membranes. We are producing membranes in rolls, cut-out sheets and tubes, both welded tubular and extruded tubular.

Our patented manufacturing line allows us to produce membranes in sizes and forms fitting common and custom industrial units.
