Desalination Technologies

Desalination technologies are methods used to remove salt and impurities from seawater to produce fresh water. The two main techniques are reverse osmosis, which forces water through a filter that blocks salt, and thermal distillation, which involves heating water until it evaporates and then condensing the vapor back into liquid, leaving salt behind. These processes help meet water needs in arid regions or places with limited freshwater sources, but they can be energy-intensive and costly, prompting research into more efficient and sustainable methods.
