What are two methods commercially available for the desalinization of water?

Two commercially available methods for desalination are reverse osmosis and thermal distillation. Reverse osmosis involves forcing seawater through a semi-permeable membrane that separates salt and impurities from the water. Thermal distillation, on the other hand, uses heat to evaporate water, leaving salts and other contaminants behind, and then condenses the vapor back into liquid form. Both methods are widely used to provide potable water in arid regions and areas with limited freshwater resources.
