Electrodeionization (EDI) is a continuous process of removing ionizable species from feedwater using DC power. Our EDI modules offer a cost-effective and chemical-free alternative to mixed-bed ion exchange resins for polishing RO permeate and eliminate the need to store and handle hazardous chemicals used for resin regeneration.

Our patented EDI module designs utilize a distinct, leak-free, low-maintenance spiral-wound design containing a membrane and IX resins, sealed in a high-strength fiberglass-reinforced plastic pressure vessel, making them an ideal choice for high purity water needs.


DOW™ EDI-310 Module can help you optimize performance, maintain continuous product quality while producing up to 18 megohm-cm product water for high purity and ultrapure industrial water applications.
