Scientists have created a filter that cleans the sea water

Australian scientists from the State Association of Scientific and Applied Research (CSIRO) have developed a new way of filtering water using graphene, the resulting material was called GraphAir.

How it works

GraphAir is made from soybean oil, whereas ordinary graphene is produced by a chemical process that requires a lot of energy. Inside the new filter there are nanocannels through which the liquid is cleaned of salts and other harmful substances. Also, the researchers found that this material is longer contaminated.
The company from CSIRO tested its invention in Sydney Bay, placing the graphene film in a normal filter. After the first filtration, the water became suitable for drinking.

Cheap and angry

Project Manager Don Khan Seo states: "Technology allows you to get clean drinking water in one step, no matter how contaminated it was originally."
The first field studies are planned to be conducted in 2019, in developing countries. In addition, this filtration method can be used to purify water from industrial waste. Development should help people who do not have access to drinking water.
"Almost a third of the world's population, about 2.1 billion people, do not have access to clean drinking water. As a result, millions of people around the world, and most often children, die every year from diseases related to lack of adequate water supply, sanitation and hygiene, "says Seo.
"GraphAir is the ideal filter for water purification. Instead of complex, time-consuming and multiphase processes, which are currently used for cleaning, it is able to cope with the task in just one step. "
