Iontech modules design

Although the general working principle is the same for all EDI modules/stacks there are differences.


Iontech is one of the few EDI manufacturers in the world that produce their own Ion-Exchange membrane specifically designed for Electro Deionisation. We are proud of our newly developed and patented membrane which is significantly better than other membrane brands on the market.

  • Highest Ion-Exchange capacity
  • Highest mechanical strength
  • Lowest electrical resistance
  • Best energy efficiency
  • Best chemical resistant


In principle, the working of EDI modules/stacks is basically based on the same Ion-Exchange technology. So the question is what makes the Iontech module better performing?

A combination of the following facts will explain:

  • Use of the latest and securely selected mixed cation and anion resins with excellent mass transfer and deionizing characteristics for optimal process operation.
  • High ion exchange capacity of the Iontech Ion-conductive membranes.
  • Minimized possible back diffusion of carbon dioxide from concentrate to dilute.
  • Low overall electrical module resistance.
  • High mechanical strength membrane which ensures a consistent quality over a long lifespan.
