The new technique, which can easily be added to current membrane-based electrodialysis desalination processes, removes nearly 100% of these toxic metals, producing a pure brine along with pure ...

This new approach to desalination — called ion-capture electrodialysis — uses thin membranes and electricity to capture toxic metals as they are pulled from water along with salts. Credit: Adam Uliana ...

The new technique, which can easily be added to current membrane-based electrodialysis desalination processes, removes nearly 100% of these toxic metals, producing a pure brine along with pure ...

The two most important parameters in electrodialysis desalination are the flow rate of the water and the power you apply to the electrodes. To make the process efficient, you need to match those two.

Concentration polarization of ion-exchange membranes in electrodialysis units limits operational current densities to the underlimiting regime, preventing process intensification by simply increasing ...

So, just for the fun of it, I tried to use these materials for water desalination. They showed quite a high performance. This is very promising work.” Picture the Planet. Three major processes are ...

Process could turn concentrated brine into useful chemicals, making desalination more efficient. The rapidly growing desalination industry produces water for drinking and for agriculture in the ...

When salt is removed from seawater in desalination plants, ... which can harm the environment. Thanks to a new treatment process, however, ... followed by one or more stages of electrodialysis.

The process used is known as “flexible batch electrodialysis” and differs from the more common reverse osmosis method. Reverse osmosis, however, requires a steady power source as it uses ...

A colleague and I then placed these membrane filters into an electrodialysis water purifier. Electrodialysis is a method that uses electricity to pull salts and toxins out of water, across a membrane ...
