Japanese offer technology to clean polluted Hanoi river
Japanese experts have promised the Vietnamese government their bionanotechnology could quickly reduce pollution in Hanoi’s To Lich River. With a length of about 14 kilometers (8.7 miles), the To Lich runs through the downtown Thanh Xuan, Hoang Mai and Thanh Tri districts. It has been heavily polluted for years and is now infamous for its black water and stench. The equipment, which includes an aerator that employs nanotechnology to quickly treat water using natural materials, will be installed on the bed of the river. The Japanese experts said the river’s stench would reduce significantly within just three days
