The Hanoitimes - Japan specialists expect to install modern equipment using bio-nanotechnology on the To Lich river to clean up the riverbed.
Prime Minister Nguyen Xuan Phuc has welcomed a proposal made by Japanese experts to treat water pollution in Hanoi’s To Lich river and West Lake by using bio-nanotechnology, saying that it meets Vietnam's actual needs.
At a meeting with PM Phuc on April 11, Tadashi Yamamura, an environmental specialist of the United Nations who leads the delegation of Japanese experts, said that the Japanese side expects to install modern equipment using bio-nanotechnology on To Lich river to clean up the riverbed.

To Lich used to be an icon of Hanoi for its beauty in the old times, but it has become black and stinky due to untreated wastewater.
By using bio-nano technology with super-fast processing speed in three days, bad smell will be reduced, Tadashi Yamamura stressed.
The technology includes nanotechnology aeration using natural substances which the Japanese side has surveyed for two years before making this proposal, said Yamamura, hoping that this technology will actively support Vietnam in wastewater treatment.
Appreciating the Japanese technology, PM Phuc said Vietnam pays special attention to environmental issues and wastewater treatment is a highly potential cooperation area in the Vietnam-Japan multifaceted relations.
He emphasized that Japan’s idea for water pollution treatment on the To Lich river and West Lake is a great idea to enhance environmental protection, and believed that the Japanese side will succeed in wastewater treatment in Hanoi.
PM Phuc asked Japanese experts and Japan – Vietnam Environment Joint Stock Company (JVE) to exchange and work with the Vietnam’s Ministry of Natural Resources and Environment and the Hanoi government to study the method and implementation in accordance with regulations, ensuring quality and efficiency.
