Advanced Technology for Desalination and Water Purification.

The article discusses the issue of water scarcity and the need for energy-efficient desalination systems to provide potable water to populations facing water shortages. It explores various physical and chemical methods of desalination, including distillation, membrane processes, and chemical treatments. The article also highlights a special issue focused on small-scale technologies for desalination and water purification, which includes articles on topics such as slow sand filtration, solar distillation, evaporation-assisted humidification-dehumidification cycles, electric field force for ion removal, and a self-regenerating solar evaporation system. These technologies offer potential solutions for individual or small group usage, as well as emergency scenarios. [Extracted from the article]
