1. Product Overview
The Veolia E-Cell MK-3 is an industrial electrodeionization (EDI) stack that uses electrical current to produce ultrapure water from suitably treated feed water. It is designed for continuous operation in applications including microelectronics rinsing and demineralized boiler feed water.
2. PRODUCT SPECIFICATIONS
Item | Specification |
Brand | Veolia E-Cell |
Model | MK-3 |
Product type | Industrial electrodeionization (EDI) stack |
Dimensions (W × H × D) | 30 × 61 × 54 cm (12 × 24 × 22 in.) |
Shipping weight | 100 kg (220 lb) |
3. OPERATING PARAMETERS
Parameter | Value / Range |
Nominal flow | 3.4 m³/h (15 gpm) |
Flow rate range | 1.6–4.5 m³/h (7.0–20 gpm) |
Recovery | Up to 96%; actual performance depends on operating conditions |
Voltage | 0–300 VDC |
Amperage | 0–5.2 ADC |
Maximum inlet pressure | 6.9 bar (100 psi); required inlet pressure depends on downstream pressure requirements, flow configuration and stack pressure drop |
Pressure drop | 1.4–2.8 bar (20–40 psi), at nominal flow and 25°C |
Feed water temperature | 4.4–40°C (40–104°F) |
Feed water pH | 4–11 |
Total exchangeable anions (TEA, as CaCO₃) | ≤63.6 ppm; stated value is at minimum flow and maximum temperature |
Feed water conductivity equivalent | ≤109 μS/cm |
Total hardness (as CaCO₃) | ≤1.0 ppm for standard counter-current operation; ≤0.1 ppm for co-current operation |
Silica (SiO₂) | ≤1.0 ppm; allowable limit decreases above nominal flow and falls to 0.5 ppm when feed water hardness exceeds 0.5 ppm as CaCO₃ |
Total organic carbon (TOC, as C) | ≤0.5 ppm |
Total chlorine | ≤0.05 ppm |
Fe, Mn and H₂S | ≤0.01 ppm |
Boron | ≤1.0 ppm; limit decreases to 0.3 ppm when a silica guarantee or a resistivity guarantee above 10 MOhm-cm is required |
Oil and grease | None detectable |
Oxidizing agents | None detectable |
Color | ≤5 APHA |
Particulate control | RO permeate or equivalent feed water; filtration immediately before the stack is required if an open system separates the RO system or other feed source from the stack |
Feed water limits and expected performance should be verified for the specific design conditions using Veolia’s Winflows projection software and the E-Cell Stack Owner’s Manual.
4. Key Features & Benefits
Continuous EDI operation: Uses electrical current and does not require acid or caustic regeneration of the ion exchange resin within the stack.
Flexible operating flow: The specified 1.6–4.5 m³/h flow range supports evaluation against the required system capacity.
Counter-current operation: Designed to minimize cleaning requirements at higher feed water hardness levels; the applicable hardness limit depends on the flow configuration.
Quality assurance: CE, RoHS, CSA and EAC marked; certified with UKCA. The stack is manufactured in an ISO 9001 and ISO 14001 facility and is Halal certified by IFANCA®.
Simplified concentrate-side requirements: The stack does not require brine injection or concentrate recirculation.
5. Key Applications
Ultrapure water for rinsing semiconductor chips, solar panels and other microelectronics.
Demineralized boiler feed water for high-pressure boilers in power plants and other heavy industrial sites.
