What is desalinization?

Desalinization refers specifically to the process of removing salt and other impurities from seawater, making it suitable for human consumption and agricultural use. As freshwater sources become increasingly scarce, especially in arid regions, desalinization has gained importance as a viable solution to provide potable water. This process typically involves methods such as reverse osmosis or distillation, which effectively separate salt and minerals from water, rendering it safe for drinking and irrigation.

Understanding this concept within the context of water supply is crucial, especially considering the growing demand for freshwater resources amid population growth and climate change. The other options do not adequately capture the specific function of desalinization and rather refer to different processes related to water purification, groundwater management, and water transportation, each of which plays an important role in overall water resource management but does not address the specific removal of salt from seawater.
