New Electrodeionization (EDI) portfolio expands flow capacity and configuration options for industrial and microelectronics water treatment systems

WILMINGTON, Del., Nov. 9, 2026 /PRNewswire/ — DuPont (NYSE: DD) today announced the launch of four new high-flow DuPont™ Electrodeionization (EDI) modules, expanding its portfolio for deionized (DI) water applications in industrial markets and selected ultrapure water (UPW) applications in the microelectronics industry.

The EDI range within the new portfolio is suitable for higher-purity water applications across industries including power generation and green hydrogen; chemical, coal-to-chemical and petrochemical processing; pulp and paper; metallurgy; solar photovoltaic production; and semiconductor chip assembly and testing.

Electrodeionization combines electrodialysis and ion exchange resin technologies to continuously remove ionized and ionizable impurities from water using direct-current power. Typically used as a polishing step following reverse osmosis, EDI provides an alternative to conventional mixed-bed ion exchange for DI water and selected UPW applications. Its continuous, chemical-free operation eliminates the need for hazardous chemical regeneration and associated chemical waste.

“The expansion of our EDI portfolio gives our customers greater flexibility to address a broader range of higher-purity water requirements,” said Gary Gu, Global Technology Director, DuPont Water Solutions “By combining high-flow EDI modules with our expertise across ion exchange, reverse osmosis and ultrafiltration, we can help customers simplify system design, operations and maintenance while supporting reliable, higher-quality water production.”

Backed by more than two decades of EDI manufacturing experience, DuPont’s expanded portfolio combines its existing spiral-wound technology with the new high-flow plate-and-frame modules. The modules incorporate DuPont ion exchange resins, ion exchange membranes and electrodes to support consistent higher-purity water production while helping reduce dilute-chamber pressure drop and electrical resistance.

The new DuPont™ EDI-520, EDI-820, EDI-530 and EDI-830 modules feature nominal product-water flow rates of 5 or 8 m³/h and are available in two- and three-outlet configurations, providing greater flexibility to meet different system requirements and customer preferences. Together with DuPont’s existing EDI-310 module, the portfolio now covers nominal product-water flow rates from 2 to 8 m³/h, supporting applications ranging from smaller installations to large-scale industrial projects.

The new modules are designed for both new installations and replacement projects, with configurations intended to accommodate the differing requirements of OEMs and end users.

Beyond EDI, DuPont offers ultrafiltration (UF) and reverse osmosis (RO) membranes for DI water pretreatment, as well as polishing resins for UPW applications. Together, these technologies give customers the option to source key water purification solutions from a single supplier, supported by DuPont’s experience in DI and UPW system design and operation.

DuPont Water Solutions technologies are helping to purify more than 50 million gallons of water every minute in 112 countries across the world. DuPont offers market-leading technologies to address a variety of challenges faced by water treatment municipalities, seawater desalination plants, and industrial water users, including the microelectronics industry, through a broad portfolio of membranes, resins and complete systems. The team is also innovating solutions that can help balance the world’s growing water and energy demands, with products that support the production of electricity, lithium and green hydrogen.
