Nanotechnology purification could help access clean water

A water filtration system that uses nanotechnology was introduced at a workshop in the Mekong Delta City of Can Tho on October 22.

Experts said the technology from the Republic of Korea (RoK) could be an effective solution to water pollution in the Mekong Delta. 

Duong Quoc Xuan, deputy head of the Steering Committee for the Southwestern Region, said even though the Mekong Delta is traversed by more than 28,000km of rivers and canals, there is still a shortage of clean water. 

Up to 75% of the region’s 18 million inhabitants live in rural areas, and most of them use water from rivers on a daily basis. Meanwhile, water resources are increasingly polluted due to agricultural and industrial production and urbanisation, which is causing an increase in the prevalence of infectious diseases in the community, he noted. 

The official said a water filtration system that uses nanotechnology could be an appropriate solution to the problem. 

Prof. Dr Hong Sik Byun, President of the Membranes Society of the RoK, gave a presentation on the water filtration system Vikowa, which is able to remove all impurities, heavy metals, arsenic and harmful organic chemicals. 

The product is powered by latent energy and can therefore be used in areas that lack access to electricity, he said, adding that first tests on Hanoi’s lakes and underwater reservoirs met the requirements for the application of the purification technique.
