July 10, 2025

Latest company news about Veolia EDI Stacks – Continuous High-Purity Water Production for Critical Industries​

Core Technical Features

Electrodeionization (EDI) Technology

  • Combines ion exchange resins with ion-exchange membranes under direct current.

  • Continuous operation with simultaneous deionization and resin regeneration (no chemicals required).

  • Removes 99.9% of ions, achieving resistivity of 15–18.2 MΩ·cm.

Veolia-Specific Innovations

  • TruTrac Flow Distribution: Patented design prevents resin fouling, extending stack lifespan to 5–7 years.

  • iON Monitoring System: Real-time tracking of conductivity, pH, and resistivity, with predictive scaling alerts.

  • Standardized scalability from 1 m³/h (laboratory) to 150 m³/h (industrial).

Chemical-Free Operation

  • Eliminates acid/caustic consumption compared to conventional ion exchange..latest company news about Veolia EDI Stacks – Continuous High-Purity Water Production for Critical Industries​ 0

Strategic Advantages

Operational Excellence

  • 40% lower OPEX than mixed bed systems (no chemical costs).

  • Less than 1% downtime.

  • 50% smaller footprint than two-bed ion exchangers.

Sustainability Leadership

  • Enables Zero Liquid Discharge (ZLD).

  • 35% lower energy consumption compared to thermal processes (0.1–0.5 kWh/m³).

  • NSF/ANSI 61 certified.

Precision Performance

  • Reduces boron/silica to below 1 ppb.

  • Integrated electrodeionization disinfection prevents biofilm formation.
