Getting electricity using solar batteries was popular in Morocco even back in the early 21st century. Now scientists are using electricity to freshen and clean seawater.
As it turns out, the method is simple, inexpensive, and very effective. Salt water goes through a fine-pored panel between two electrodes. Electric current divides the water stream into two. In one, the level of salt increases; in the second, it decreases. At a certain threshold, an electric current creates a shockwave and abruptly divides the areas of fresh and salt water with a simple physical barrier. The new method replaces traditional filters and membranes, which require constant cleaning and replacement. This also results in high-quality disinfection of water. So now, there are stationary freshwater facilities as well as mobile ones, which can be used during emergencies or natural disasters.
