Veolia E-Cell MK-9 EDI Stack (formerly MK-7) For Large-Scale Industrial Ultrapure Water Production
The Veolia E-Cell MK-9 EDI Stack (formerly MK-7) represents the high-capacity solution in Veolia's EDI portfolio, delivering 6.0-10.0 m³/hr of continuous ultrapure water for demanding industrial applications. With its enhanced flow capacity and proven reliability, this stack is specifically engineered for large-scale operations where consistent high-purity water production is critical.
Featuring the same advanced electrodeionization technology as other E-Cell models, the MK-9 eliminates chemical regeneration while maintaining superior product water quality (>16 MOhm-cm resistivity). Its robust construction and optimized hydraulic design ensure stable performance in challenging operating conditions across power generation, semiconductor manufacturing, and large-scale industrial water treatment plants.

Key Advantages:
High-flow capacity: 6.0-10.0 m³/hr production range
Proven reliability in large-scale industrial applications
Zero chemical consumption for regeneration
Consistent high-purity output (>16 MOhm-cm)
Direct upgrade path for existing MK-7 installations
Applications:
Semiconductor and microelectronics manufacturing
Power plant boiler feed water systems
Large-scale pharmaceutical water systems
Solar panel production and green hydrogen applications
