Electrodeionization (EDI) is a pure water production technology that combines ion exchange resin adsorption technology, ion exchange membrane exchange technology, and electro-ion migration technology. The ion exchange membrane element is filled with mixed anion and cation exchange resins. The anions and cations in the influent are first adsorbed by the ion exchange resin, and under the action of the electric field, the anions and cations adsorbed by the ion exchange resin are removed through the ion exchange membrane. At the same time, water molecules decompose into hydrogen ions and hydroxide ions under the action of the electric field, and these ions continuously regenerate the ion exchange resin filled between the membrane elements, and the regenerated ion exchange resin also greatly increases the speed at which ions are removed, so that the entire EDI system maintains a high efficiency state.
