EDI E-Cell Stack MK-3

Summary

Product identification

The E-Cell EDI MK-3 Stack is an industrial electrodeionization (EDI) stack designed to produce ultrapure water for applications such as semiconductor fabrication, power generation, and solar panel production.

Key features:

• Uses electrical current to provide ultrapure water.
• Delivers high levels of product water quality and low energy consumption.
• Minimizes cleaning requirements at higher feed water hardness levels using counter-current operation.
• Guaranteed leak-free with a standard 3-year prorated warranty.
• Operates continuously, requiring no caustic or acid for regeneration of ion exchange resin.
• Requires no brine injection or concentrate recirculation.

Typical applications include:

• Ultrapure water for rinsing of semiconductor chips, solar panels, and other microelectronics.
• Demineralized boiler feed water for high-pressure boilers.

Quality Assurance

• CE, RoHS, CSA, and EAC marked.
• Manufactured in an ISO 9001 and ISO 14001 Facility.
• Certified with UKCA.
• Halal certified by the Islamic Food and Nutrition Council of America (IFANCA®).

Mechanical / hydraulic

• Nominal Flow: 3.4 m³/h (15 gpm)
• Flow Rate Range: 1.6 – 4.5 m³/h (7.0 – 20 gpm)
• Shipping Weight: 100 kg (220 lbs)
• Dimensions (width x height x depth): 30 cm x 61 cm x 54 cm (12'' x 24” x 22”)

Product water

Guarantees available:

• Resistivity: ≥ 16 MOhm-cm
• Sodium: ≤ 3 ppb
• Silica (SiO₂): As low as 5 ppb
• Boron: As low as 0.08 ppb (contact Veolia for guarantees)
• Note: Actual performance may vary depending on site conditions. Consult Winflows projection software or contact Veolia for specific guarantees.

Typical Removal Efficiencies:

• Sodium: ≥ 99.9% removal
• Silica (SiO₂): Up to 99% removal
• Boron: Up to 96% removal

Operating limits

• Recovery: Up to 96%
• Voltage: 0–300 VDC
• Amperage: 0–5.2 ADC
• Inlet Pressure: ≤ 6.9 bar (100 psi)
• Pressure Drop: 1.4–2.8 bar (20–40 psi) at nominal flow and 25°C.

Feed water

• Total Exchangeable Anions (TEA as CaCO₃): ≤ 63.6 ppm. (Represents concentration of all anions, including OH⁻, CO₂, and SiO₂. This value is at minimum flow and maximum temperature; Winflows software must be used to confirm acceptability for specific applications.)
• Conductivity Equivalent: ≤ 109 μS/cm
• Temperature: 4.4–40˚C (40–104˚F)
• Total Hardness (as CaCO₃):
  • ≤ 1.0 ppm for standard counter-current flow operation.
  • Decreases to 0.1 ppm for co-current flow operation.
• Silica (SiO₂):
  • ≤ 1.0 ppm.
  • Allowable limit decreases above nominal flow.
  • Decreases to 0.5 ppm with feed water hardness above 0.5 ppm as CaCO₃.
• Total Organic Carbon (TOC as C): ≤ 0.5 ppm
• Total Chlorine: ≤ 0.05 ppm
• Fe, Mn, H₂S: ≤ 0.01 ppm
• Boron:
  • ≤ 1.0 ppm.
  • Limited to 0.3 ppm as B when a silica guarantee or resistivity guarantee above 10 MOhm-cm is required.
• pH: 4 to 11
• Oil & Grease: None detectable
• Particulate: RO permeate or equivalent. RO permeate is specified because EDI stacks contain packed beds of ion exchange medium that cannot be backwashed/fluidized to remove particulate matter. Systems with an open system between an RO system and E-Cell must be fitted with filters immediately preceding the E-Cell (generally 5 µm absolute or 1 µm nominal).
• Oxidizing Agents: None detectable
• Color: ≤ 5 APHA (APHA is a color standard/scale defined by ASTM D1209).
