DESALINATION OF WATER USING ELECTRODIALYSIS

DESALINATION OF WATER USING ELECTRODIALYSIS. Matthew Baissa.

Departmental Research. I took an interest in the Product and Process Systems Engineering core research group Prof. David Bogle released an article on " Water desalination by capacitive electrodialysis: Experiments and modelling " (2020).

What is Electrodialysis?. Molecules. Electrodialysis is a type of membrane-based process that converts saline (salt water) into fresh water using the following ion exchange membranes: Anion Exchange Membranes (AEM) Cation Exchange Membranes (CEM) The other, more commonly used method is reverse osmosis.

Tackling the Grand Challenges. Electrodialysis addresses: 1) Human wellbeing – Potential to provide fresh water to millions in drought prone regions. 2) Sustainable cities – Electrodialysis has a lower energy consumption compared to other desalination methods, thus being more economical and sustainable..

Conclusion. Whilst reverse osmosis currently dominates the desalination market, the growing demand for sustainable methods will eventually catalyse the widespread use of electrodialysis..
