Reverse osmosis and electrodeionization water demineralizer

The demineralizers of the Galileo series are based on the innovative principle of electro-deionization (EDI) – shown in the scheme – that permits production of extremely pure water without using chemicals.

In the devices of the Galileo series, water undergoes two sequential demineralization treatments: water is first treated by reverse osmosis (a dual stage treatment in some devices) with an average 99.5% salt rejection; then, water is treated by  electro-deionization. In this process, a mixed bed of cationic/anionic ion-exchange resins is used that are continuously regenerated by means of an electrical field. The scheme shows that the EDI unit is equipped with an outlet for demineralized water and a drain for concentrated salt water, that  is recycled back to the reverse osmosis unit inlet.

The produced demineralized water attains purity values with a resistivity of up to 18,3 MW/cm (equal to a conductivity of 0,056 µS/cm).
