Editorial of the special issue on advanced electrochemical technologies for environmental applications

This special issue of Separation and Purification Technology gathers 27 articles, which are related to keynotes and oral or poster presentations at the 2nd European Workshop of Electrochemical Engineering entitled ‘New Bridges for a New Knowledge on Electrochemical Engineering’. The workshop was held from 1st to 5th October 2017 in Barcelona (Spain), as a Joint Event of the 10th World Congress of Chemical Engineering (WCCE10). This congress was promoted by the World Chemical Engineering Council (WCEC), the European Federation of Chemical Engineering (EFCE) and the European Society of Biochemical Engineering Sciences (ESBES) to approach researchers and specialists in all areas of chemical engineering and to improve their strategy for the development of innovative processes that will be vital for the society of tomorrow. The joint event was promoted by the Working Party on Electrochemical Engineering (WPEE) of the EFCE and co-organized with the Spanish Excellence Network on Environmental and Energy Applications of the Electrochemical Technology (thus being the 2nd Workshop of E3TECH Network). It took place at Fira de Barcelona, one of the most important trade fair institutions in Europe
