DuPont Launches High-Flow Electrodeionization Modules for Higher-Purity Water Applications

DD
  • DuPont launched four new high-flow Electrodeionization (EDI) modules to expand its deionized water portfolio for industrial and microelectronics applications.
  • The new EDI range supports higher-purity water needs in sectors including power generation, green hydrogen, chemical processing, pulp and paper, metallurgy, solar photovoltaic production, and semiconductor manufacturing.
  • EDI technology combines electrodialysis and ion exchange resins to continuously remove impurities using direct-current power, offering a chemical-free alternative to conventional mixed-bed ion exchange.
  • The expanded portfolio integrates existing spiral-wound technology with new high-flow plate-and-frame modules incorporating DuPont resins, membranes, and electrodes to reduce pressure drop and electrical resistance.
  • Four specific new modules (EDI-520, EDI-820, EDI-530, & EDI-830) feature nominal flow rates of 5 or 8 m³/h and are available in two- or three-outlet configurations.
  • Combined with the existing EDI-310 module, the portfolio now covers nominal flow rates from 2 to 8 m³/h to support projects ranging from small installations to large-scale industrial systems.
  • The new modules are designed for both new installations and replacement projects, accommodating the varying requirements of OEMs and end users.
  • DuPont Water Solutions technologies currently purify over 50 million gallons of water per minute across 112 countries while supporting solutions for electricity, lithium, & green hydrogen production.
  • Gary Gu, Global Technology Director, stated the expansion provides greater flexibility to simplify system design, operations, & maintenance while ensuring reliable water quality.
