ELECTRODEIONISATION
Electrodeionisation is a process used to produce very high quality demineralised water for the energy, pharmaceutical and electronics sectors.

offers you compact, modular units that are fully automated and integrate the entire pre-treatment process
This technology combines reverse osmosis and ion exchange. It takes the form of modules made up of cationic and anionic resins mixed together and placed between two selective reverse osmosis membranes, one cationic and the other anionic. The ions to be removed are captured by the resins and then transferred to the selective membranes using an electric current generated by a set of electrodes. Electrodeionisation, combined with pre-treatment by reverse osmosis, makes it possible to achieve a very high resistivity of demineralised water > 18 MΩ at low cost and without the use of chemicals.
