Turning the To Lich River into drinking water

After 10 years of research, Prof. Tran Hong Con, a lecturer of chemistry at the Hanoi University of Science, successfully applied selective adsorption technology to treat dirty water into instant drinking water.

On the banks of the To Lich River, the river is famous for its dirty and foul-smelling black water. Professor Con takes the river water into the filter, the pure water flows out. Without hesitation, he brought water to his mouth. Some of the people watching him for the rehearsal yesterday also tried it.

"I drink normally, the water has no smell , " a woman drinks and says.

According to Tran Hong Con, his goal is to help people living in areas where water is polluted, where floods have enough clean water to eat and drink ... So, over the years, has launched technology that can filter any water into clean water for direct drinking.

Prof. Con said that the water purifier is classified in four stages to treat heavy metals, organic substances and ammonium, arsenic and sterile. Previously, chlorination or ultraviolet sterilization was quite complex, but today silver nanoparticles are used for sterilization.

Selective Absorption Technology is a method of coating nanoparticles onto the surface of superhuman materials creating a large area of contact between the nanotubes and water molecules. Hazardous substances are held tight by the bonding forces of molecules, the treatment completely without the use of chemical reactions, the chemical should be absolutely safe.

In addition, Professor Tran Hong Con also applied the technology of sterilization using Nano Silver is applied in advanced countries in the world. Nanosky uses superhuman materials coated with silver nanoparticles of 10 to 30 nanometers. When water flows through the material, 99.99% of bacteria, viruses in the water will be destroyed.

Ha Anh Son, director of a company specializing in nanotechnology, said that based on the technology that GS. Dr. Tran Hong Con invented this product has been testing products for 3 years, to bring the source to be treated to meet the standards of bottled water certified by the Directorate for Standards and Quality. Especially, water filters do not need electricity, so they can be applied in many terrain conditions.
