A bunch of researchers led by an Indian-Origin scientist have found an energy efficient material which can be used to remove salt from sea water. This makes the water drinkable. The energy material is a nanometre-thick sheet of molybdenum disulfide (MoS2) riddled with tiny holes called nanopores.
It is designed to let high volumes of water to go through. The salt content and other contaminations will be let out through a process called desalination. MoS2 has shown greatest efficiency in filtering more than 70% than graphene membranes.
The research heard Narayana Aluru who is also a professor at University of Illinois said, "This is a low cost and efficient way to purify sea water. We can make good strides in solving water crisis.
These days most desalination technologies are based on reverse osmosis process which pushes sea water through a thin plastic membrane. They are good to take out the salt. But they provide little amount of fresh water. But with this energy efficient material we can get more water."
