RALEX® electro separation membranes

RALEX® ion exchange membranes

In-house researched and manufactured since 1985

Did you know...

We are shipping our RALEX® separation membranes immediately and worldwide!

The first industrial application was cleaning of contaminated uranium mining water and has proven its efficiency. Electroseparation solves two issues at once: minimizes the amount of waste and recovers valuable ingredients from the effluent stream.

The RALEX® membranes provide excellent mechanical and electrochemical properties. High heat and chemical stability allow use in different industries including food processing and a lifetime up to 10 years. Low resistivity and high permselectivity keep the operation cost down and provide reliable separation.

We have been researching and manufacturing membranes since 1985. The Membrane Innovation Center with experienced experts and state-of-the-art equipment pushes boundaries of possible in electromembrane separation. New membranes are more efficient and last longer.

Why choose RALEX® ion exchange membranes

RALEX® ion exchange membranes for different industries and processes

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

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.
