New Desalination Technique Also Cleans and Disinfects Water
Electrodialysis has the potential to desalinate seawater quickly and cheaply but does not remove other contaminants such as dirt and bacteria.
One of the world’s most pressing needs is to supply clean drinking water to the its population.
The most common method is to distil seawater in a vacuum so that its boiling point is lower than usual.
This works by pumping water through a membrane that does not allow sodium or chlorine ions to pass.
That’s significantly less energy intensive than traditional desalination methods but is limited by the rate at which water can pass through the membrane.
