Only 3 days to 'fly' the smell of To Lich river: What is Japanese technology placed on the bottom of the river?

Learn about Japanese technology that promises to clean up this To Lich River.

During the meeting on the afternoon of April 11 at the Government headquarters with Prime Minister Nguyen Xuan Phuc, the delegation of Japanese experts on the environment proposed to grant bio-nano biotechnological equipment for free support to the treatment of water pollution in Vietnam.

Dr. Tadashi Yamamura - United Nations expert on environment, Chairman of Japan Environment & Trade Promotion Organization, is the leader of Japan's expert group, said the device has super fast processing speed. but only 3 days will help reduce the smell of pollution.

In the short term, bio-nano technology will be piloted in the riverbed at a section of To Lich river and a corner of West Lake to expand the application model for many other localities.

So what is bio-nano biotechnology?

Dr Tadashi Yamamura said nanotechnology uses natural materials so it is environmentally friendly (something chemical and physical methods do not have). This is a technology that combines biology and nanotechnology.

If biotechnology has really become an industry in the late 1970s, nanotechnology is a new issue when studying anything related to small-sized structures. more than 100nm.

More specifically, nanotechnology is science, engineering and manipulation involving nanoscale systems, in this micro-size structure, nanoparticles, nanocrystals, nanotubes, and nanotubes will There are new features and functions that scientists need to study.

Biotechnology, based on recombinant technology, will focus on the molecular-level processes and mechanisms of biological systems. It can be seen that the study of the structure and properties of the micro level of matter is the common point of both technologies.

The combination of these common points is an inevitable consequence of the introduction of nano-biotechnology (bio-nanotechnology) , the industry that seeks to link the nanoscale objects.

In particular, "Bio2Nano" is the combination of using materials and biological structures (incorporating nanomaterials (NMs)) to create technical systems where Japanese water filters with self-assembled functional films are placed under The above mentioned To Lich river bottom is a typical example.

These functional films will be made up of nano-sized particles like metal-oxide NPs (including aluminum oxide, TiO2 and zeolite), antimicrobial materials (including silver-NPs (Ag-NPs) and CNTs) and photocatalyst materials (such as bimetallic-NPs, TiO2).

Nanoscale molecules will arrange or combine with each other into structures that have superior properties to increase permeability, odor deodorization, biofilm control, sustainability against heat or mechanical impact, self-cleaning ability .

Prospects of nano biotechnology .

The study of green biotechnology using bio-nano technology is now a sustainable development direction in many countries. Not only wastewater but bio-nano technology can also be used to clean up oil spills on the sea, air pollution, soil .

Prime Minister Nguyen Xuan Phuc highly appreciated this technology of Japan and expressed his willingness to cooperate in this potential area to enhance environmental protection during the period of industrialization and modernization of the land. water.

Japan is a country with experience in wastewater treatment and has brought its technology to many countries like Cambodia and Indonesia . so the Prime Minister also believes in the success of Japanese people at this pilot.

The Prime Minister proposed that Japanese experts and Japan Vietnam Environment Improvement Joint Stock Company (JVE) together with the Ministry of Natural Resources and Environment and Hanoi People's Committee make plans and organize the real Show the most effective after exchanging and working specifically.

The results of this pilot will be a good foundation for dealing with water pollution in many other localities experiencing similar problems in Hanoi.
