Water desalination

Water desalination is the process of removing salt and other impurities from seawater or brackish water to produce fresh, drinkable water. This is typically done through methods like reverse osmosis, where water is forced through a semi-permeable membrane that allows water molecules to pass while blocking salts and contaminants. Desalination helps provide clean water in regions facing shortages, supporting agriculture, industry, and households. Though energy-intensive and costly, advances in technology are making desalination more efficient and accessible, offering a sustainable solution for increasing global freshwater supplies.
