Veolia™ EDI E-Cell Stack E-Cell-3X ultrapure water Resistivity ≥ 16 MOhm-cm Nominal Flow ≥ 5.0 m³/h (22 gpm) edi systems

Veolia's E-Cell* electrodeionization (EDI) technology effectively removes residual salts and ionizable aqueous species, including carbon dioxide, silica, ammonia, and boron, from various water sources. These EDI systems are centered around a core component known as an EDI stack, and Veolia offers multiple options of E-Cell stacks tailored to suit a wide range of applications. Additionally, Veolia provides pre-engineered EDI systems that cater to specific needs. Whether you purchase E-Cell stacks or a comprehensive system, Veolia boasts the necessary expertise, global reach, and proven performance, ensuring confidence in your ultrapure or high purity water system.

General Description

The E-Cell-3X Stack, a core component of the E-Cell* electrodeionization product line, is engineered to serve a diverse range of industries, ensuring ultrapure water for crucial processes. Here's a comprehensive overview of its key features and benefits:

Electrical Current Utilization: The E-Cell-3X Stack leverages electrical current to produce ultrapure water, crucial for semiconductor manufacturing, power generation, solar panel production, green hydrogen generation, and numerous other heavy industries.

Premium Performance: This stack offers unparalleled performance, delivering the highest standards of product water quality while achieving the lowest energy consumption.

Minimized Cleaning Requirements: Its counter-current operation efficiently minimizes the need for frequent cleaning, even when dealing with feed water with higher hardness levels.

Leak-Free Design: The E-Cell-3X Stack is designed to be completely leak-free, backed by a standard 3-year prorated warranty for peace of mind.

Continuous Operation: It operates seamlessly without the need for any caustic or acid for ion exchange resin regeneration within the stack, ensuring continuous production of ultrapure water.

Eliminated Brine Injection & Concentrate Recirculation: The stack operates efficiently without the need for brine injection or concentrate recirculation, simplifying the overall water treatment process.

Typical Application Scenarios

Product water from the E-Cell-3X can be reliably used to meet 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.

For ease of design and greater confidence in your EDI application, we offer E-Cell performance predictions and guarantees, which you can obtain through Winflows* software or by contacting us.

Quality Assurance

-CE, RoHS, CSA & EAC marked

-Manufactured in an ISO 9001 and ISO 14001 facility

-Certified with UKCA

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

Notes:

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.
