Tedagua and Tecnalia enter into a business partnership agreement to develop a new desalination technology through capacitive deionization

Tedagua has entered into a business partnership agreement with the Tecnalia Research and Innovation Foundation to jointly develop capacitive deionization (CDI) seawater desalination technology.

Today, reverse osmosis is the go-to technology in the water desalination process. Capacitive deionization could be an alternative to this technology, which involves installing electrodes (anodes and cathodes) that attract salt ions when an electric current is applied to them.

Álvaro Díaz, Head of Tedagua's R&D Department, says that “Developing new desalination techniques is one of the strategic lines of research for the company. Tecnalia is a leading research center in Europe. If we add their track-record of success in the field of research to our know-how in the desalination market, it is a perfect combination.”

The benefit of this new technology when compared to the now-traditional reverse osmosis is twofold. On one hand, it has a direct impact on energy savings -which is the bulk of the cost of the desalination process- and on the reduction of CO2 emissions. On the other, it increases the percentage of recovered water.

Thanks to this partnership for the development of deionization technology, Tedagua positions itself in the research, development and innovation of new technologies that allow for a responsible use of the environment and support the accomplishment of sustainable development goals.
