Desalination
Electrodyalisis Process (exchange membranes)
This is a desalination process in which electronically separated ions are transferred through a membrane from a less concentrated solution to a higher concentrated solution. This basic chemical reaction gives a continuous electrical current.
Reversible Electrodyalisis (RED) is a version of Electrodyalisis in which the poles of the electrodes are reversed several times per hour. This induces a chemical self-cleansing process. The process allows us to desalinate water sources obtaining high levels of recuperation (around 90%) with minimum pre-treatment and low operation costs (0.15 – 0.20 €/m3).
