Veolia E-Cell MK-3 EDI Stack for Continuous High-Purity Water Production
The Veolia E-Cell MK-3 Electrodeionization (EDI) Stack is designed for the continuous production of high-purity water, effectively removing ionized and weakly ionized substances from reverse osmosis (RO) permeate. It delivers ultra-pure water with resistivity up to 18 MΩ·cm without the need for chemical regeneration, reducing operational costs and environmental impact. Ideal for industries such as power generation, pharmaceuticals, microelectronics, and semiconductors, the MK-3 stack ensures reliable performance, high system recovery rates, and stable operation under varying conditions. Its robust construction supports long service life and minimal maintenance, making it a critical component in industrial water purification systems
