VEOLIA EDI MK-7 Module Continuous Electrodeionization EDI Stack
General Description
As part of the E-Cell electrodeionization product line, the E-Cell MK-7 Stack is designed to:
• Use electrical current to provide ultrapure water for power generation, solar panel production, green hydrogen generation and many other heavy industries.
• Deliver premium performance including both the highest levels of product water quality and the lowest energy consumption.
• Minimize cleaning requirements at higher feed water hardness levels using counter-current operation.
• Be leak free, guaranteed with standard 3-year prorated warranty.
• Operate continuously and require no caustic or acid for regeneration of ion exchange resin within the stack.
• Require no brine injection or concentrate recirculation.
Features:
(1) Higher and stable quality water product;
(2)No need for acid-base regeneration;
(3)Continuous running,simple peration;
(4)Less requirements and cost in installation;
(5)Modular system,more flexible,easy to expand;
(6)No generation chemical waste;
(7)Reduced facility requirements;
(8)Low cost in running and maintenance;
(9)Easy to integrate into existing water systems;
(10)No recirculation-increased reliability.
Typical Applications
The product water from the E-Cell MK-7 can be relied upon to meet today’s most demanding ultrapure water applications including:
• Demineralized boiler feed water for high pressure boilers found in power plants and other heavy industrial sites
• Ultrapure water for rinsing of solar panels and other microelectronics
• Ultrapure water for electrolyzer green hydrogen generation

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.
