After 10 years of research, Professor Tran Hong Con, a professor of chemistry, Hanoi University of Science, successfully applied the selective absorption technology to treat dirty water into drinking water immediately.
On the banks of To Lich River, Professor Con took the muddy river water into the filter, the pure water slowly flowing out. Without hesitation, he brought the water to his mouth to drink. Some people watching him do the experiments yesterday also took a drink.
"I drink it normally, the water has no smell", one woman drank and said.
According to Tran Hong Con, his aim is to help people living in areas with polluted water sources, flooded areas have enough clean water to eat and drink ... Therefore, through many years of research, he gave Technology can filter any water into clean water to drink directly.
Professor Con said that the water purifier is classified into four layers to specialize in handling heavy metals, organic matter and ammonium, arsenic and sterilization layer. Previously, the sterilization technology with chlorine or ultraviolet rays was quite complicated, but now silver nanotechnology is applied for sterilization.
Selective absorption technology is a method of coating nano-size metal magnets on the super-porous material surface, creating an extremely large contact area between types of nanomagnets and water molecules. Toxic substances are held tightly by the binding force of molecules, the treatment absolutely does not use chemical reactions, so it is absolutely safe.
In addition, Professor Tran Hong Con also applied antibacterial technology with Nano Silver which is being applied in advanced countries around the world. Nanosky uses a super hollow material coated with silver nanoparticles ranging in size from 10 to 30 nm. When water flows through this material, 99,99% of bacteria and viruses in the water will be destroyed.
Mr. Ha Anh Son, director of a company specializing in applying nanotechnology, said, based on the technology that GS. Invented by Dr. Tran Hong Con, this unit tested the product for 3 years, to give the source treated to ensure the bottled water standards certified by the Directorate for Standards, Metrology and Quality. In particular, the water purifier does not need electricity, so it can be applied in many terrain conditions.
