The Spanish Desalination and Reuse Association (AEDyR), celebrated last October its XII International Congress. The event aims to offer an international forum attended by experts in water desalination, treatment and reuse. Numerous companies, public institutions, universities and research centres attended the event, in which the latest innovations were presented, thus promoting the exchange of knowledge, techniques and ideas. In this framework, the EOLUTION project, funded within the framework of the SODERCAN programme boosting R&DE actions, was presented within the framework of the congress, raising an interesting discussion on alternatives with greater implementation feasibility. EOLUTION aims to be an important step in the efficient treatment of liquid effluents.
