˄ Demineralization - Ion exchange water treatment systems Continuous electrodeionization (EDI) The EDI process eliminates the ions dissolved in the water using a technology that combines semi-permeable membranes with ion exchange resins, which are regenerated thanks to a continuous electric current applied to the resins. In this way, the use of hydrochloric acid and sodium hydroxide for regeneration is completely eliminated. EDI is used as a finishing process to further demineralize the reverse osmosis permeate producing “ultrapure” quality water, reaching a resistivity of 18 Mhom * cm. It is normally applied on pharmaceutical processes or high pressure boilers for steam production for turbines. DEYOLIT automatic demineralization Fully automatic demineralization units designed for medium-high flows. They are available both in double column version (separate cationic and anionic, DEYOLIT NRC) or in mixed bed version with cationic and anionic resins inside a single container (DEYOLIT MB). There is a control system capable of monitoring the quality of the water produced and automatically activating regeneration when the quality of the water does not meet the requirements.
