The E-Cell MK-3 is an electrodeionization (EDI) module from Veolia Water. It utilizes a direct current (DC) electric field to deeply deionize and polish reverse osmosis (RO) product water, enabling continuous and stable production of ultra-high-purity water. It is particularly suitable for industrial applications with stringent water quality requirements.
1. Core Working Principle
EDI technology cleverly combines electrodialysis with ion exchange. Under the influence of a DC electric field, ions in the feed water are adsorbed by ion exchange resins and directed through anion and cation exchange membranes, respectively, into the concentrate chamber where they are removed, producing high-purity water. Simultaneously, the current ionizes water molecules, generating hydrogen and hydroxide ions that continuously regenerate the resin, eliminating the need for acid or alkaline chemicals.
