The benefits of hybridising electrodialysis with reverse osmosis

In a recently published paper in the Journal of Membrane Science, Prof. Syed Zubair, Prof. Lienhard and I reported on how the cost of achieving high purity water with electrodialysis, an electrically driven technology, can be reduced through hybridisation with reverse osmosis, a pressure driven technology. In reverse osmosis, water is pressurised and forced through a membrane thatContinue reading “The benefits of hybridising electrodialysis with reverse osmosis”

Desalination: Is it better to remove the water or the salt?

This blog is based upon “The cost effectiveness of electrodialysis for diverse salinity applications” by Ronan K. McGovern, Syed M. Zubair and John H. Lienhard, published in Desalination. For researchers of new desalination technologies, the question of whether and why salt removal makes economic sense is a very important and relevant one. At present, theContinue reading “Desalination: Is it better to remove the water or the salt?”
