Veolia Suez EDI Stacks E-Cell MK-3 For Semiconductor Industry

Working principle of EDI
In EDI equipment, various ions in the influent are removed after being exchanged with resin, and the water is purified. At this time, the ion exchange principle is used to remove ions in the water. Since voltage is applied to both sides of the membrane, water molecules are electrolyzed into hydrogen ions and hydroxide ions to regenerate the resin. At the same time, the ions exchanged by hydrogen ions and hydroxide ions are migrated to the concentrated water chamber under the action of current and discharged, thereby achieving the purpose of continuous regeneration and continuous use.
(1) The influent is distributed to each chamber in the EDI module;
(2) Various ions migrate to the corresponding electrodes under the action of direct current;
(3) As with the mixed bed, various ions in the water are exchanged by ion exchange resins, and then the exchanged ions migrate to the concentrated water through their respective ion exchange membranes. The water in the fresh water chamber flows out of the module (only ions can pass through the ion exchange membrane, but water cannot) and becomes pure water.
(4) The concentrated water circulates in the concentrated water chamber. In order to improve and maintain the conductivity of the concentrated water chamber, most of the concentrated water is circulated;
(5) A small part of the circulating concentrated water needs to be discharged and supplemented by the influent water. This part of the discharged concentrated water can be returned to the previous RO device for reuse;
(6) Water molecules are ionized into hydrogen ions and hydroxide ions under the action of voltage, and migrate to the resin layer through their respective ion exchange membranes to continuously regenerate the resin.

E-Cell's reliable modular EDI technology has high cost-effectiveness for various water treatment volumes. Now this technology has become the industry standard for EDI technology that does not require chemical regeneration.
The new product standard EDI module MK-3 is mainly used in the power, semiconductor, and microelectronics industries. The advantages of the E-Cell EDI module MK-3 series products are high water production, stable water quality, strong performance controllability, and low energy consumption.
The biggest difference between EDI module MK-3 series products and other companies' EDI
1. The polar water is discharged separately, making the system safer and more reliable
2. The membrane plate spacing does not need to be manually adjusted on site, reducing the possibility of module leakage caused by human factors
3. Each E-CellEDI module must undergo 31 factory tests and issue quality before leaving the factory. All E-CellTM modules have obtained CSA and NRTL/C certification and ISO14000 certification, and have CE mark.
GE EDI module MK-3 series water production requirements: If the inlet water meets the inlet water quality requirements and the system is operated according to the operating instructions, the E-Cell™ module can produce 16MOhm.cm of water (MK-3, MK-3 Mini) or 10MOhm.cm of water (MK-3 Pharm).
EDI module MK-3 series product features
1. Provide ultrapure water for industries such as power, semiconductor, chemical, metallurgy and general industry
2. Continuously produce ultrapure water of mixed bed water quality
3. No need to regenerate the mixed bed resin in the module
4. Guarantee no water leakage
5. No need for brine injection and concentrated water circulation, simplifying the design
EDI module MK-3 series product quality assurance
1. With CE, UL and CSA marks
2. Manufactured by ISO 9001:2000 certified factory
EDI module MK-3 series product description and use
E-CellEDI module MK-3 series is an electrodeionization GE-EDI module that uses electric current to deionize and polish reverse osmosis water. E-CellEDI module MK-3 produces ultrapure water, suitable for today's most demanding industries for water quality.

These quality assurances provide customers with the confidence that the E-Cell MK-3 Stack meets rigorous standards in terms of safety, reliability, and environmental sustainability.

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.
