Product Description
The Veolia E-Cell MK-5 Electrodeionization (EDI) Module is designed for continuous, chemical-free production of high-purity water, delivering flows up to 5 m³/h (22 GPM) with resistivity ≥16 MΩ·cm and silica removal to ≤5 ppb. Ideal for boiler feedwater in power plants and ultrapure water applications in semiconductors, microelectronics, and pharmaceuticals, it operates at up to 97% recovery without acid/caustic regeneration. The module features a compact design (30x61x72 cm), hot-water sanitization capability, and compliance with CE, RoHS, and ISO 9001/14001 standards. Its robust construction ensures low maintenance and stable performance under varying feedwater conditions, supported by Veolia’s global technical expertise

Veolia's E-Cell ® EDI (Electrodeionization) technology represents the gold standard in continuous demineralization, offering a chemical-free, high-efficiency alternative to traditional mixed-bed ion exchange. Designed for industries requiring ultra-pure water, Veolia EDI stacks combine ion-exchange resins and selective membranes with direct current to remove contaminants—including silica and boron—without regeneration chemicals.
- Zero Chemical Regeneration - Eliminates acid/caustic handling, reducing operational costs and safety risks.
- Consistent High Purity - Produces water with > 16 MΩ*cm resistivity and < 5 ppb silica, meeting stringent standards for semiconductor, pharmaceutical, and power industries.
- Energy-Efficient Design - Patented resin configuration and counter-current operation minimize power consumption and scaling risks.
- Modular & Scalable - Available in MK-3, MK-5, and MK-9 stacks, supporting flows from 1.6 to 10 m³/h with up to 97% recovery.
- Validated Reliability - CE, FDA, and Halal certified, manufactured in ISO 9001/14001 facilities with 85 °C hot-water sanitization options (PharmHT series).
- Microelectronics: Ultrapure rinse water for semiconductor fabrication.
- Pharmaceutical: USP/EP-compliant purified water.
- Power Generation: High-purity boiler feedwater.
- Industrial Processes: Steel, chemical, and LNG plant demineralization.
Backed by Veolia's performance guarantees and global technical support, E-Cell EDI delivers sustainable, low-maintenance pure water solutions.

The water produced by the E-Cell-3X reliably meets today's most demanding ultrapure water applications, including but not limited to:
- Ultrapure water for rinsing semiconductor chips, solar panels, and other microelectronic devices.
- Demineralized feed water for high-pressure boilers in power plants and other heavy industrial sites.
- Ultrapure water for green hydrogen generation in electrolyzers.
To simplify design and enhance your confidence in EDI applications, we offer E-Cell performance predictions and guarantees, which are available through Winflows* software or by contacting us.
