Membrane-free electrochemical water-treatment method also generates power

This article was originally posted on Chemical Engineering Online.

Summary

Researchers at Samsung Electronics and Sungkyunkwan University developed a membrane-free electrochemical water treatment that removes ions (such as calcium, magnesium, and bromine) and simultaneously generates power. By harvesting energy during the electrode-regeneration cycle and eliminating ion-exchange membranes, the approach aims to reduce cost and complexity compared with conventional systems.

Which applications do you think would benefit most from a membrane-free, power-generating water treatment system—industrial brine management, municipal pretreatment, or decentralized/remote installations?

Electrochemical water-treatment technologies facilitate the adsorption of ions, effectively removing contaminants such as calcium, magnesium, bromine and more. Such processes, however, are often hampered by the high costs associated with electrode regeneration and the use of ion-exchange membranes. A new electrochemical system developed by researchers from Samsung Electronics Ltd. and Sungkyunkwan University takes advantage of the electrode-regeneration cycle to harvest additional power, while eliminating ion-exchange membranes altogether.
