After more than a month of piloting, in addition to the ability to handle odors, Japan's nano-bioreactor technology also brought significant changes to To Lich River, Hanoi.

After a week of putting the waste treatment machine into the river, the water of To Lich river was clearer and the odor was reduced significantly.

Compact aerators such as water treatment plants are submerged in the river with a promise of only 3 days will make a difference.
