Title: Preparation of Anion Exchange Membranes using recycled membranes as support for water treatment: towards the circular economy approach

Presenter: Amaia Lejarazu-Larrañaga

Affiliation: Membrane Technology research group at IMDEA Water institute (Madrid, Spain)

Abstract: In this webinar, a new methodology for the preparation of Ion Exchange Membranes, using discarded Reverse Osmosis membranes as mechanical support will be presented. These novel membranes have been prepared by casting a polymeric mixture on the pretreated surface of the discarded Reverse Osmosis membrane. The resulting membranes have been tested in desalination by electrodialysis, selective electro-separation, Donnan Dialysis and Ion Exchange Membrane Bioreactor processes. This research could open an alternative within the recycling of discarded Reverse Osmosis membranes, avoiding landfilling and moving membrane technology into a circular economy.
