WATECH (Advanced Treatments for Water Sustainability in Europe and China) aims to connect the advanced water treatment research activities carried out by European and Chinese scientists. This Research Staff Exchange Action, with the main objective of creating and providing a solid basis for EU-China collaboration in environmental and water studies, is built on previous contacts between Chinese and European researchers.WATECH will identify common needs for solving water pollution problems, analyze topics and initiatives of scientific cooperation, map competences and potentials of Chinese researching organizations and major infrastructures, investigate strategic development plans and initiate roadmaps for future collaborations. It will improve the visibility of research initiatives and strengths of Chinese institutions in European investigation centers. Project can lead into future actions with Chinese organizations.According to this, the specific aims of the WATECH initiative are:• To share knowledge on advanced water treatment and sustainable management• To reinforce research cooperation between European and Chinese scientists within the water related sciences• To provide optimized training on site about water treatment technologies• To support the existing researching initiatives and programs through staff exchanges• To build links between research scientists working in advanced water treatment, environmental research and the end users of their science for future collaborations
