Australian researchers have developed a new light responsive technology that can convert seawater into drinking water within 30 minutes. Through molecular sieving process, this hollow framework of pores separates salty solute in the seawater and absorbs salts and other impurities in the water in 30 minutes under dark conditions.
The MOF is then regenerated so that it can be reused within four minutes and the adsorbed salts are removed with the help of sunlight. MOF helps in filtering out harmful particles from water and producing This technology is claimed to be more energy-efficient than the present desalination practices, including reverse osmosis. Although thermal desalination process through a mix of evaporation method and solar energy is mostly used for producing drinking water, it requires high energy.
The scientists could achieve a TDS of less than ppm within 30 minutes.

This is the process in which salty seawater can be transformed into fresh water. There are many ways to desalinate water, but one of the most effective is membrane desalination.
In this method, water is pushed through a thin membrane with tiny holes. A conductive metal-organic framework MOF is a new type of membrane for water desalination. In his latest research, Barati Farimani explores the potential of a new type of membrane, called a metal-organic framework MOF. The organic compound and metal connect in a pentagonal pattern, leaving a hole in the center that serves as a pore.
There are a couple of reasons why the framework is more effective. Additionally, the placement of the pores helps with permeation. So why is seawater such an attractive water resource that we go through all those costly process to make it safe to drink? Here are a few reasons Seawater provides an unlimited, reliable water supply for coastal populations worldwide; brackish water is a plentiful, relatively drought-proof water resource for inland populations and reduces dependency on imported water.
And, of all the Earth's water, 97 percent is salt water, only 1 percent is fresh water available for humans to drink, and 2 percent is frozen. To date, only a limited number of desalination plants have been built along the California coast, primarily because the cost of desalination is generally higher than the costs of other water supply alternatives available in California e.
However, as drought conditions occur and concern over water availability increases, desalination projects are being proposed at numerous locations in the state. Desalination costs are decreasing as technology improves and more plants are built. Today there are more than 15, desalination plants in countries. About half of the world's desalted water is produced with heat to distill fresh water from seawater.
The distillation process mimics the natural water cycle in that salt water is heated, producing water vapor that is in turn condensed to form fresh water. One such treatment process is called Multi-Stage Flash Distillation.
