Japanese expert swims in Tô Lịch River’s treated water

The zone consists of four tanks. The first reservoir is an anaerobic treatment tank, in which a bioreactor plate for activating anaerobic microorganisms is provided, giving the substrate for microorganisms.

The second tank is an aerobic tank, in particular, a nano aerator for the planning of aerobic microorganisms.

The third is a tank for decomposing organic mud. Inorganic mud will accumulate at the riverbed.

The fourth tank is for the post-treatment water which has reached Vietnamese standards and can be used as domestic or bath water.

Dr Tadashi Yamamura, UN environment expert and President of the Japan Environment and Trade Promotion Organisation said the nano-bioreactor has proved its worth in similar cases in Japan, China and the US and believed their technology could be of use in Việt Nam after two years of surveying.

“In Việt Nam, one of the biggest problems with the Tô Lịch River is the thick sludge at its bed that is the source of the smell, and this could be solved by the nano bioreactor,” he said.

The equipment was placed on the bed of a  三00-metre section of the river.

The device creates and diffuses nano-gas streams into the surrounding water to stimulate microorganisms, which helps to release oxygen and decompose the mud in the riverbed, making the water cleaner. — VNS
