Infinite Water Supply

Aug-11-20 A group of international researchers have found a way of purifying slightly salty water and seawater into drinkable fresh water with the help of metal-organic frameworks (MOFs) and sunlight.

The researchers developed a new MOF, which is a porous material consisting of metal ions that covers a large area, called PSP-MIL-53, that traps impurities and salt contained in seawater and brackish water.

Their experiment showed that this MOF reduced solids in water from 2233 ppm to less than 500 ppm, below the 600 ppm threshold for potable water. Furthermore, this feat was achieved in under thirty minutes, and requires less energy than other desalination procedures.

This method of purifying water could guarantee water to regions with no source of fresh water, and could be the end of water shortages, because the availability of salty water is almost without end, as 71% of Earth's surface is covered by seawater, and sunlight is practically infinite.
