Reverse electrodialysis (RED) using a bipolar membrane to suppress inorganic fouling around the cathode

Water Research, 2019
When operating reverse electrodialysis (RED) with several hundreds of cell pairs, a large stack voltage of more than 10 V facilitates water electrolysis, even when redox couples are employed for the electrode reaction. Upon feeding natural water containing multivalent ions, ion crossover through a shielding membrane causes inorganic scaling around the ...

Nanocomposite reverse electrodialysis (RED) ion-exchange membranes for salinity gradient power generation

Journal of Membrane Science, 2014
Abstract Despite the important role of ion-exchange membranes (IEMs) in reverse electrodialysis (RED) systems, the current absence of proper ion-exchange membranes delays the sustainable development of the RED process for salinity gradient power generation. This research presents the preparation of a new type of organic–inorganic nanocomposite cation

Evaluation of energy harvesting from discharged solutions in a salt production plant by reverse electrodialysis (RED)

Desalination, 2019
Abstract Reverse electrodialysis (RED) is a promising membrane–based process to harvest energy based on the salinity gradient between two solutions. In the RED process, cation exchange membranes (CEM) and anion exchange membranes (AEM) stack alternatively between high and low concentrate compartment (HCC & LCC) which lead to migration of the cations ...
