On the morning of May 20, after 3 days of testing and cleaning To Lich river with Nano-Bioreactor technology , 2 independent units are taking samples of water for testing. Samples will be preserved in the right way. As observed, water samples are quite clear and have many microorganisms.
The sampling unit said that the results of the in-depth tests were done in the laboratory and would result in a week. Representatives of the sampling units said that rapid test results showed that the alkalinity and dissolved oxygen in the test area had positive changes, the river water had less odor.
'The stench has improved, normal weather like this, can not stand here without a mask, especially the cycle of Buoi - Hoang Quoc Viet road because here the wind is blowing in the opposite direction, the smell is very strong. In particular, the river water is no longer floating like before. Indeed this is an unexpected result for me , 'said Nguyen Duc Minh, a commoner walking through the area to assess.
Ms. Nguyen Thi Gai (residing at the beginning of Nguyen Dinh Hoan street) also said that after 3 days of testing new technology, the water in To Lich river in this area has less smell.'We are very grateful and appreciate Japanese experts when they come here to swim so dirty mud to test the technology. This initial result is very praiseworthy for the people living on the To Lich River like us, " said Ms Gai.
Regarding the cost of this technology, many people are interested and exchanged with PV Capital Security Newspaper, Mr. Nguyen Tuan Anh, Chairman of the Board of Directors of Nhat Viet Environmental Improvement Joint Stock Company, said this technology is "technology of wastewater treatment plants located in rivers and lakes" so the total cost is much cheaper than current technology. This technology requires only initial investment at a much lower cost than the construction of a wastewater treatment plant.
Nhat Viet Environment Improvement Joint Stock Company said that it will continue to appoint people to directly operate the system and believe that after 2 months of operation, the water in To Lich River will change unexpectedly .
