22 Gpm Veolia MK-5 EDI Module Boiler Feedwater In Power Plants

Veolia EDI Technology – Advanced Electrodeionization for High-Purity Water

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.

Key Advantages:

✔ 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).

Global Applications:

• 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.

Typical Applications

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.

Parameter data

Veolia offers the following E-Cell EDI stacks with recommendations on the typical new-build application.

Quality Assurance

CE, RoHS, CSA, and EAC Marks

Made in an ISO 9001 and ISO 14001 compliant facility

UKCA Certified

E-Cell-3X Stacks are Halal certified by the Islamic Food and Nutrition Council of America (IFANCA®)

Note:

1. Actual performance may vary based on site conditions. Refer to Winflows Prediction Software to verify expected product water quality and the resistivity, sodium and silica performance guarantees provided at design conditions. Contact us for boron or other guarantees.

2. Inlet pressure is determined by downstream pressure requirements for product and concentrate streams, choice of countercurrent or cocurrent operation, and stack pressure drop.

3. At nominal flow and 25°C. Refer to Winflows Prediction Software to verify design conditions.

4. Refer to Winflows Prediction Software and the E-Cell Stack Operating Manual to verify feedwater specifications at design conditions.

5. TEA (ppm as CaCO3) - Total Exchangeable Anions, this represents the concentration of all anions in the feedwater, including contributions from OH-, CO2 and SiO2. Winflows must be used to confirm that the feedwater TEA is acceptable at the given application operating conditions. Tabulated values are given at minimum flow and maximum temperature.

6. The 1.0 ppm feedwater hardness limit as CaCO3 is for standard countercurrent operation only. Under co-current operation, the allowable feed water hardness is reduced to 0.1 ppm as CaCO3.

7. At rates above nominal flow, the allowable silica limit is reduced. When feed water hardness exceeds 0.5 ppm as CaCO3, the allowable silica limit is reduced to 0.5 ppm.

8. When a silica guarantee requirement exists or a resistivity guarantee requirement is above 10 MOhm-cm, the boron feed level is limited to 0.3 ppm as B, as higher boron levels may affect performance. In the absence of these requirements, the limit is 1.0 ppm boron.

9. Reverse Osmosis (RO) or Equivalent Feed Water: RO provides feed water to the EDI that is essentially free of particulate matter, colloidal materials, and high molecular weight organic matter that could foul the ion exchange media. Because the EDI stack contains packed beds of ion exchange media that cannot be backwashed/fluidized to remove particulate matter, the quality of the RO permeate needs to be specified. Systems with an open system between the RO system (or other source) and the E-Cell (e.g., storage tank, decarbonator) must have a filter installed immediately before the E-Cell to protect the E-Cell from contamination by particulate matter. Generally, a 5µm absolute filter or 1µm nominal filter is acceptable.
