#Solar-powered #desalination
A new system could make #brackish #groundwater drinkable at low cost in communities where #seawater and grid power are limited. The system is a variation of a previous design based on #electrodialysis, which uses an electric field to draw out salt ions as #water is pumped through a stack of ion-exchange membranes.

#Desalination system adjusts itself to work with renewable power

In #electrodialysis, "the membranes are arranged in such a way that the #water flows along them. On both sides of those membranes are positive and negative electrodes that create an electric field, which draws salt ions through the membranes and out of the water."

The system adjusts the flow rate of the water and the power applied to the electrodes to match the available solar power, no batteries needed.
