The water we drink in peacetime is basically fresh water. It consists of water in rivers and lakes, high mountains of snow, glaciers and groundwater. Without water, there is no life. Only 3% of the water on Earth is Fresh water, all land life is ultimately dependent on fresh water. In order to solve this problem, scientists from Australia created a water filter that can pass highly-polluted seawater through only one time through a new type of graphene called Graphair. Filter it and drink it.
According to researchers, about 2.1 billion people worldwide do not have access to clean and safe drinking water, millions of people die every year due to diseases related to lack of water supply, poor sanitary conditions, etc. Therefore, he hopes to create a perfect purified water filter. Device.
Graphair uses a graphene made from soybean oil, which is cheaper and easier to produce than traditional graphene manufacturing methods. The most prominent feature of this material is hydrophobicity, which allows water to pass through but can Block larger molecules of pollutants.
After the scientists added Sydney's seawater to the filter, they found that the filter screened out 99% of the pollutants, and even if covered with contaminants, it could still work. The researchers said: No matter how dirty the water is, only one step is needed. Drinkable.
The team that invented Graphair stated that we hope to conduct trials in residential areas in developing countries next year to help them with urban water filtration, as well as seawater and industrial wastewater treatment.
