DuPont launches high-flow electrodeionization modules for higher-purity water

Product launch

DuPont expanded its Electrodeionization (EDI) portfolio with four high-flow modules — EDI-520, EDI-820, EDI-530 and EDI-830 — aimed at deionized (DI) water applications in industrial markets and selected ultrapure water (UPW) uses in microelectronics. The additions increase available nominal product-water flows and system configuration options.

Design and technology

The expanded range combines DuPont’s spiral-wound technology with new plate-and-frame modules and leverages DuPont ion exchange resins, ion exchange membranes and electrodes. The modules are engineered to help reduce dilute-chamber pressure drop and electrical resistance and are backed by more than two decades of EDI manufacturing experience.

Performance and configurations

The new modules provide nominal product-water flows of 5 or 8 m³/h and are offered in two- and three-outlet configurations. Together with the existing EDI-310, the portfolio now covers nominal flows from 2 to 8 m³/h. Modules are intended for both new installations and replacement projects, with configurations to accommodate OEMs and end users.

Applications and system integration

Electrodeionization is positioned as a continuous, chemical-free polishing step typically following reverse osmosis, serving industries including power generation, green hydrogen, chemical and petrochemical processing, pulp and paper, metallurgy, solar PV production, and semiconductor assembly/testing. DuPont also supplies UF and RO membranes and polishing resins to support DI and UPW pretreatment and polishing within integrated solutions.
