The Challenges and Potential of Desalination: Turning Saltwater into Freshwater

TLDRDesalination, the process of removing salt from seawater, is an important technology for addressing water scarcity. However, it is energy-intensive, expensive, and has environmental impacts. Distillation and reverse osmosis are the two main methods of desalination. Both methods have their own challenges and complexities. While desalination can provide a reliable source of water during drought conditions, it is not always the most cost-effective option. The private sector plays a role in financing and operating desalination plants. The future of desalination lies in technological advancements and the utilization of alternative water sources.
