Desalination is the process of removing salt from seawater. This process produces fresh water that can be used for drinking, farming, and other activities. Desalination plants are a promising source of clean water in dry regions.
Desalination plant: A facility that removes salt from seawater to produce drinking water. Reverse Osmosis: A process used by desalination plants to filter salt out of seawater. Distillation: A process used by desalination plants to evaporate seawater and collect the resulting fresh water.
Desalination plants are able to produce potable water out of salt water from the ocean and other sources. The biggest desalination plant in the world is located in Ras Al-Khair, Saudi Arabia and produces up to 1 million cubic meters of water every day. The energy required to power desalination plants has a very low carbon footprint compared to other sources of freshwater.
