Making desalination more eco-friendly: New membranes could help eliminate brine waste

Desalination plants, a major and growing source of freshwater in dry regions, could produce less harmful waste using electricity and new membranes made at the University of Michigan.

Lotus leaf-like solar evaporators for saltwater treatment

Arul Ganesh S S Mumbai 17 Apr 2025 Freshwater scarcity is a significant issue in various parts of the world and is expected to intensify in the coming years. While water is abundant on Earth's surface, only about 3% of it is freshwater, and even within that, less than 0.05% is easily accessible. Removing salt (desalination) from seawater and brackish water is seen as one of the solutions to address this problem, with researchers working towards …

Environmental News Network - Making Desalination More Eco-Friendly: New Membranes Could Help Eliminate Brine Waste

Membranes packed with charge help overcome the current salinity limit, making it easier to crystallize ocean salts and harvest valuable minerals from desalination waste.

Scientists find way to turn saltwater into freshwater without the waste

Desalination plants turn seawater into drinking water, providing a critical resource for many dry regions around the world. But this process comes with a big downside: for every liter of fresh water produced, it creates about 1.5 liters of salty waste, known as brine. Globally, desalination plants produce over 37 billion gallons of brine waste […] The post Scientists find way to turn saltwater into freshwater without the waste appeared first on …
