ReWAdd project showcased at the 50th I.T.I.M. conference on Ion Transport in Organic and Inorganic Membranes held in Sochi

Some of the first results of ReWAdd related to WP1: Nutrient extraction and concentration were presented at the International Conference on “Ion Transport in Organic and Inorganic Membranes”, I.T.I.M. 2026 held in hybrid mode in Sochi on 24-29 May.

Dr. Kayo Santana-Barros, Postdoctoral researcher of the UPV team, presented the poster entitled “Transport of nutrients present in multicomponent ionic solutions resembling urban wastewaters through ion-exchange membranes”. In the study, different ion-exchange membranes were characterized by means of chronopotentiometry and linear sweep voltammetry using real effluent of the WWTP El Saler (València) and synthetic solutions resembling the ionic composition of the effluent. These results include preliminary tests to evaluate the electrical resistance of membrane materials and define the operating conditions at which electrodialysis systems could be operated for extracting nutrients such as phosphate and ammonia ions from urban wastewaters. The results are part of the activities conducted under the participation of the UPV team in the València Urban Sandbox.

The conference was organized by the Membrane Institute of the Kuban State University, and gathered several international experts in the field of ion transport in electromembrane processes. It represented an excellent opportunity to exchange fundamental knowledge related to ion transport, as well as to discuss practical solutions to specific challenges, such as the use of electrodialysis for the extraction and concentration of nutrients.
