EDI (Electrodeionization) is a kind of pure water manufacturing technology that ion exchange technique, IX membrane technique and ion-conductance migrating technology are combined.It combines electrodialysis and ion exchange technique cleverly, utilizes the two end electrodes high pressure to make that charged ion moves in the water, and cooperates ion exchange resin and selective resin film to move removal with speeding-up ion, thereby reaches the purpose of desalt.
Principal feature:
1, connect the EDI device after the reverse osmosis equipment, further remove the ion in the water, making and producing into water is high purity water, and resistivity is more than 5M Ω cm;
EDI equipment is to be applied in after the r-o-, replaces traditional mixed bed ion switching technology (MB-DI) and produces stable ultrapure water.The EDI technology has been compared following advantage with the hybrid ionic switching technology: 1, water conditioning; 2, realize full automatic control easily; 3, can not shut down because of regeneration; 4, do not need chemical regeneration; 5, working cost is low; 6, little by 7, the without sewage discharge of plant area.
The EDI principle of work:
The EDI module is filled ion exchange resin to be clipped in and is formed the EDI unit between the anion/cation exchange membrane.The EDI principle of work is as shown in the figure.Separate with the lattice plate between EDI unit, form dense hydroecium and freshwater room with some amount in the EDI module.The group two ends are provided with the moon/positive electrode in the unit again.Under galvanic promotion, pass anion and cation exchange membrane respectively through the zwitterion in the freshwater room current and enter into dense hydroecium and remove at freshwater room.And take ion out of system through the water of dense hydroecium, and becoming dense water. EDI equipment generally feeds water as EDI with two-pass reverse osmosis (RO) pure water.RO pure water resistivity generally is 40-2 μ S/cm (25 ℃).EDI pure water resistivity can still be provided with according to deionized water purposes system configuration up to 18 M Ω .cm (25 ℃), and the EDI ultrapure water is applicable to that preparation resistivity requires the pure water at 1-18.2M Ω .cm (25 ℃).
