Electrodeionization (EDI) is typically used in combination with RO systems to produce pure or ultrapure water, continuously and without chemicals. This combination eliminates the need for regeneration chemicals and the inherent cost, safety and inconveniences of storage, handling, treatment and discharge associated with ion exchange systems.

Power plants, electronics manufacturers and pharmaceutical companies are taking advantage of ihe benefits of EDI.

While the majority of these systems use first generation plate and frame design, the spiral wound version has become the fastest growing technology in the EDI field.

The spiral wound membrane design incorporates a fiberglass pressure vessel more similar to reverse osmosis (RO) membranes. Spiral wound EDI provides some specific advantages in terms of cost competitiveness, leak elimination and better toleration of feed water, particularly hardness.
