Hanoi Taps Japanese Nano-bioreactor Technology to Clean Most Polluted River

Authorities in Vietnam’s capital city of Hanoi on May 16 began a project to clean a section of its infamous To Lich River by using Japanese nano-bioreactor technology, state media reported. Experts and workers have installed nanotechnology equipment in a 300-meter section of the severely polluted river. It is expected to start reducing the stench within three days and decompose waste and mud at the bottom in two months. They installed water treatment devices in the bed of To Lich district in the section between the Buoi-Hoang Quoc Viet intersection and Cau Giay district. Five such devices were seen on the first day. The Japanese team said they will add more later. The project’s cost, defrayed by the Japanese side, has yet to be announced. According to the municipal Department of Natural Resources and Environment, over 200 sewage outlets discharge into the river 150,000 cubic meters of untreated household wastewater every day. The efforts to clean the To Lich river and the West Lake began after a Japanese delegation headed by Yamamura met Prime Minister Nguyen Xuan Phuc last month and offered to provide their bionanotechnology equipment for free.
