DuPont Adds Four High Flow EDI Water Modules
DuPont high-flow EDI modules add 5 or 8 m³/h water treatment options for industrial and microelectronics applications.

DuPont has launched four high-flow electrodeionization modules for industrial deionized water and selected microelectronics ultrapure water applications. The EDI-520, EDI-820, EDI-530 and EDI-830 offer nominal product-water flow rates of 5 or 8 m³/h and two- and three-outlet configurations. Together with the existing EDI-310, the portfolio covers nominal product-water flow rates from 2 to 8 m³/h. The modules are intended for new installations and replacement projects.
Higher Purity Water Applications
The new range is suitable for higher-purity water applications in 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 after reverse osmosis, it provides an alternative to conventional mixed-bed ion exchange for DI water and selected UPW applications.
Expanded Module Options
DuPont’s expanded portfolio combines its existing spiral-wound technology with new high-flow plate-and-frame modules. The modules incorporate DuPont ion exchange resins, ion exchange membranes and electrodes, and are designed to help reduce dilute-chamber pressure drop and electrical resistance.
Gary Gu, Global Technology Director at DuPont Water Solutions, said:
“The expansion of our EDI portfolio gives our customers greater flexibility to address a broader range of higher-purity water requirements. 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.”
Single Supplier Water Treatment
Beyond EDI, DuPont offers ultrafiltration and reverse osmosis membranes for DI water pretreatment, plus polishing resins for UPW applications. DuPont Water Solutions technologies are helping to purify more than 50 million gallons of water every minute in 112 countries across the world.
