Welcome Conference Attendee, 

We are delighted to announce that the International Working Group on Capacitive Deionization and Electrochemical Ion Separation will host the 8th International CDI&E Conference in Seoul, Korea, in October 2026.

The central theme of CDI&E 2026 is “Carbon Neutral Technologies” and “Sustainable Development” in deionization processes. The conference will not only showcase the latest advancements in core CDI and electrosorption technologies but will also address pre-treatment and post-treatment strategies, underscoring a comprehensive approach toward sustainable and energy-efficient water and resource recovery solutions.

This event will provide a global platform to explore:

• Cutting-edge developments in electrode and membrane materials

• Advances in theoretical and modeling approaches

• Integrated processes and novel system configurations

• Emerging frontiers in battery deionization, selective separations, resource recovery, and CO₂ capture and conversion
  
  

Beyond scientific exchange, CDI&E 2026 offers a unique opportunity to share innovative ideas, present your latest research, and build new collaborations within the international community.

We warmly invite you to join us in Seoul, one of Asia’s most vibrant and dynamic cities, for this exciting gathering of researchers, innovators, and practitioners dedicated to shaping the future of sustainable deionization technologies.

See you in Seoul,
Best regards, 8th CDI&E 2026 committee
