Veolia EDI E-Cell Stack MK-7 Recovery up to 97 %ultrapure water edi systems

Veolia's E-Cell* electrodeionization (EDI) technology eliminates residual salts and ionizable aqueous species - such as carbon dioxide, silica, ammonia, and boron - from your water sources. EDI systems are constructed around the core component called an EDI stack. Veolia offers several choices of E-Cell stacks to suit a wide range of applications and also supplies pre-engineered EDI systems. Regardless of whether you purchase E-Cell stacks or a complete system, Veolia possesses the expertise, global reach, and proven performance to instill confidence in your ultrapure or high purity water system. 

The following figure shows GE, Suez and Veolia from left to right (all the same product: MK-7 EDI Stack).

 As a component of the E-Cell* electrodeionization product line, the E-Cell MK-7 Stack is designed to:
• Utilize electrical current to supply ultrapure water for power generation, solar panel production, and numerous other heavy industries.
• Provide top-notch performance, encompassing both the highest standards of product water quality and the lowest energy consumption.
• Minimize cleaning demands at higher feed water hardness levels through counter-current operation.
• Be leak-proof, guaranteed.
• Operate continuously and entail no caustic or acid for the regeneration of ion exchange resin within the stack.
• Require no brine injection or concentrate recirculation.
The product water from the E-Cell MK-7 can be trusted to meet the most rigorous ultrapure water applications of today, including:
• Demineralized boiler feed water for high pressure boilers in power plants and other heavy industrial sites.
• Ultrapure water for rinsing solar panels and other microelectronics.
Quality Assurance
• Marked with CE, RoHS, CSA, and EAS.
• Manufactured in an ISO 9001 and ISO 14001 facility.
• E-Cell MK-7 Stacks are halal certified by the Islamic Food and Nutrition Council of America (IFANCA)  

Typical Applications

The product water from the E-Cell MK-7 can be relied upon to meet the most demanding ultrapure water applications of today, such as: 

- Demineralized boiler feed water for high pressure boilers in power plants and other heavy industrial sites. 

- Ultrapure water for rinsing solar panels and other microelectronics. 

- Ultrapure water for electrolyzer green hydrogen generation.

Quality Assurance

- Marked with CE, RoHS, CSA, and EAC. 

- Manufactured in an ISO 9001 and ISO 14001 facility. 

- Certified with UKCA. 

- The E-Cell MK-7 Stacks are Halal certified by the Islamic Food and Nutrition Council of America (IFANCA®).

Notes:

1. Actual performance may vary depending on site conditions. Reference Winflows projection software to verify expected product water quality as well as the resistivity, sodium, and silica performance guarantees that are offered for the design conditions. To obtain boron or other guarantees, contact Veolia.

2. Inlet pressure is determined by the downstream pressure requirements for the product and concentrate streams, the choice of counter-current or co-current operation, and stack pressure drop.

3. At nominal flow and 25°C. Reference Winflows projection software to verify for design conditions.

4. Reference the Winflows projection software and the E-Cell Stack Owner’s Manual to verify feed water specifications for the design conditions.

5. TEA (ppm as CaCO3) - Total Exchangeable Anion, this represents the concentration of all of the anions present in the feed water including contributions from OH-, CO2 and SiO2. Winflows must be used to confirm the feed water TEA is acceptable at the specific applications’ operating conditions. Table value is at minimum flow and maximum temperature.

6. 1.0 ppm as CaCO3 feed water hardness limit applies to standard counter-current flow operation only. Allowable feed water hardness decreases to 0.1 ppm as CaCO3 in co-current flow operation.

7. Allowable silica limit decreases above 5 m3/h flow. Allowable silica limit decreases to 0.5 ppm with feedwater hardness above 0.5 ppm as CaCO3.

8. The boron feed level is limited to 0.3 ppm as B whenever there is a silica guarantee requirement or resistivity guarantee requirement above 10 MOhm-cm, as higher boron levels could impact performance. Without these requirements the limit is 1.0 ppm boron.

9. Reverse Osmosis (RO) or equivalent feed water: RO provides EDI feed water that is substantially free of particulate matter, colloidal material and high molecular weight organic substances, which can foul ion exchange media. RO permeate quality is specified since EDI stacks contain packed beds of ion exchange medium that cannot be backwashed/fluidized to remove particulate matter. Systems with an open system between a RO system (or other source) and E-Cell (ex. tank, decarbonator) must be fitted with filters immediately preceding the E-Cell, to protect the E-Cell against contamination with particulate matter. Generally, a 5 µm absolute or 1 µm nominal filter will be acceptable.

10. APHA - color standard/scale named for the American Public Health Association and defined by ASTM D1209.
