Compact aerators such as water treatment plants are submerged in the river with a promise of only 3 days will make a difference.
On May 16, at the beginning of the To Lich River (Hanoi), the project launch ceremony took place "Sponsoring a pilot to clean a section of To Lich river and a corner of West Lake with Japanese Nano - Bioreactor technology". direction of the Prime Minister and Hanoi City People's Committee.
To Lich River flows through the center of the capital, from a poetic river that has become "dead river" due to daily receiving up to 150,000 cubic meters of domestic wastewater and industrial waste water.
The source of the To Lich River in the previous day is connected to the Red River and West Lake, creating a regular flow.However, since the French blocked the line to build Cau Go Street, this river no longer had large water flow but only limited flow with the basin is the residential areas of the city.
At the groundbreaking ceremony, Mr. Nguyen Tuan Anh, CTO of Nhat Viet Environmental Improvement Joint Stock Company believed in the success and effectiveness of the project.Affirming the project will significantly improve the environment, overcome the strong stench and will "reborn" the To Lich river.
The machines with the design are quite simple and compact.According to investors, these machines are capable of handling up to 1.35 million cubic meters of wastewater per day and night, 9 times the amount of waste water that To Lich River must receive during the same time.From that, it can be expected that waste water will always be thoroughly treated without any sedimentation and stinking in To Lich river.
The electric energy-processing machines, which are submerged in the riverbed, create a diffuse nano-gas stream into the water, stimulating the microorganisms to work, thereby releasing oxygen, processing sludge, creating Fresher water.
A water treatment machine has been placed in front of a sewer and is beginning to operate.
The Japanese expert explained the performance of the machines right at the To Lich river bank.
Currently, the project has just deployed some water treatment machines at the watershed of To Lich River and a corner of West Lake.According to information from the organizers, within 3 days these machines were able to create miracles.
In the hot and stuffy days to come, perhaps the people of the capital will "hold their breath" to wait for the expected change in this river section.
