Electrodeionization (EDI) is an electrically driven water treatment technology that uses electricity, ion exchange membranes, and resins to remove ionized species from water.
Ion exchange in the EDI system is continuously generated, unlike resin-based demineralization systems. Typically, product water resistivity of >15 MΩ.cm is consistently achieved using this process. In addition to the advantages of practical operation and reduced downtime during regeneration, EDI can also provide more consistent product purity levels than resin-type ion exchange systems.
