Making seawater drinkable in minutes

A new alternative seawater desalination membrane to produce drinking water

30-Jun-2021

According to the World Health Organization, about 785 million people around the world lack a clean source of drinking water. Despite the vast amount of water on Earth, most of it is seawater and freshwater accounts for only about 2.5% of the total. One of the ways to provide clean drinking water ...
