With the help of metal-organic frameworks (MOFs) and sunlight, a global team of researchers has been able to purify brackish water and seawater into clean drinking water that meets the suggested quality of the World Health Organization.

According to the announcement, the new technology is more energy-efficient than current desalination processes and only uses one kilogram of MOF per day to generate 139,5 liters of clean water.

Lead author Professor Huanting Wang from the Department of Chemical Engineering at Monash University in Australia has stated that "desalination has been used to address escalating water shortages globally. Due to the availability of brackish water and seawater, and because desalination processes are reliable, treated water can be integrated within existing aquatic systems with minimal health risks".
