Introduction to Veolia E-Cell MK-3 Stacks
In the world of high-purity water treatment, Electrodeionization (EDI) has revolutionized how industries achieve ultrapure water without the heavy chemical burden of traditional ion exchange methods. At Purecowater, we are proud to function as a distributor and OEM for industry leaders like Veolia, providing top-tier solutions such as the Veolia E-Cell MK-3 EDI Stack.
This comprehensive product guide explores the capabilities, specifications, and advantages of the MK-3 stack, a core component designed for reliable ultrapure water production in power generation, microelectronics, and heavy industry.
What is the Veolia E-Cell MK-3 EDI Stack?
The E-Cell MK-3 is an electrodeionization stack developed by Veolia Water Technologies & Solutions. It serves as the heart of EDI systems, utilizing electrical current to continuously remove ionization aqueous species—such as residual salts, silica, carbon dioxide, ammonia, and boron—from feed water. By effectively polishing reverse osmosis (RO) permeate, the MK-3 produces water of exceptional quality (up to 18 MOhm-cm resistivity) required for sensitive industrial processes [watertechnologies.com].
Unlike traditional mixed-bed deionization which requires periodic shutdowns for chemical regeneration, the MK-3 operates utilizing a continuous electrical regeneration process. This ensures a steady stream of high-quality water without the downtime or handling of hazardous caustic and acid chemicals.
Key Specifications and Performance
The MK-3 is engineered for versatility and high performance in “new-build” or retrofit applications. Below are the critical technical specifications that make it a preferred choice for system integrators and end-users:
- Nominal Flow Rate: 3.4 m³/h (approx. 15 gpm), with an operating range generally between 2.3 and 6.4 m³/h [lenntech.com].
- Recovery Rate: Up to 97%, making it a highly water-efficient solution.
- Contaminant Removal: Excellent rejection of silica and boron, crucial for high-pressure boiler feed and semiconductor rinsing.
- Operating Conditions: Designed for an inlet pressure up to 6.9 bar (100 psi) and temperatures up to 40°C (104°F) [lenntech.com].
Primary Applications
The Veolia MK-3 stack is specifically tailored for industries where water purity is non-negotiable. Its robust design supports:
- Power Generation: Producing demineralized boiler feed water to prevent scaling and corrosion in high-pressure turbines and boilers.
- Microelectronics & Semiconductor: providing ultrapure water for rinsing wafers, flat panel displays, and solar photovoltaic manufacturing [watertechnologies.com].
- General Industry: Supporting chemical processing and other heavy industrial applications requiring low-conductivity water.
Advantages Over Traditional Ion Exchange
Transitioning to Veolia E-Cell MK-3 EDI stacks from conventional mixed-bed ion exchange offers significant operational benefits:
- Chemical-Free Operation: Eliminates the need for acid and caustic soda for resin regeneration, simplifying Environmental, Health, and Safety (EHS) compliance.
- Continuous Production: No need to take the system offline for regeneration, minimizing the risk of “breakthrough” where exhausted resin allows contaminants to pass.
- Compact Footprint: The modular design reduces facility space requirements compared to bulky ion exchange vessels and associated chemical storage tanks [watertechnologies.com].
- Cost-Effectiveness: Lower operating expenses (OPEX) over time due to reduced chemical purchasing and waste neutralization costs.
