The amount of fresh water that humans can use is 2.5%, and the remaining 97.5% is seawater or salt water, while most countries around the world are severely deficient in water. Water as a source of life is very important. How to solve the problem of water resources has become the number one problem for countries and regions. Recently, Chinese scientists of Australian descent have made major breakthroughs in seawater desalination technology. Scientists have successfully invented filtration membranes that can directly convert seawater filtration into drinking water. The problems of domestic drinking water and industrial water can be effectively solved.
Before new desalination technology has been announced. In modern industrial production of mankind, a large amount of water resources are used. Open source and throttling is the best way to solve water scarcity. Although many modern enterprises install water circulation systems, they can only alleviate the situation of water scarcity and still cannot reduce water waste. phenomenon. Friends who have common knowledge in physics must know that distilling fresh water from the sea is a time-consuming and labor-intensive process. Scientists have made other attempts based on this, but have not yet developed efficient methods.
Australian Chinese scientists used graphene technology to produce a graphene filter membrane. The film is crystal clear and thin as a cicada. Such an inconspicuous piece of paper can actually filter the foul seawater from above and meet the standard for converting drinking water. freshwater.
This technology is actually not uncommon. Scientists completed experiments a few years ago. Because graphene films were too expensive to manufacture, it was obviously unrealistic to achieve large-scale seawater desalination. Australian scientists of Chinese descent have developed graphene films, using soybean oil as a raw material in daily life. The produced films retain the characteristics of graphene films and have low production costs.
Why can graphene filter membranes achieve seawater desalination? The micro-nano channels on the membrane only allow water molecules to pass through, and other substances are isolated. Compared to traditional filter materials, this new type of graphene membrane can be reused. Even if the surface is blocked by some impurities and pollutants, the filtration performance is still guaranteed . Currently, experimenters are stepping up to test the practicality of the film.
If this seawater desalination technology can be promoted on a large scale, it can directly filter water from the sea, and no longer need to worry about the lack of freshwater.
