The Vietnam Agricultural Genetics Institute has tested a new technology for cleaning polluted rivers, canals, and ditches that have been contaminated for years, as well as for treating wastewater directly in the drainage system that flows into these bodies of water.
The severe pollution of water affecting the daily life and living environment of local residents has long been a source of concern, particularly recently when it was discovered that the water from the To Lich River was the cause of toxic contamination in vegetables consumed in Thanh Tri. In response to this situation, the Vietnam Agricultural Genetics Institute has developed active compounds C1 and C2 using Fenton’s catalyst to clean the water and eliminate unpleasant odors. C1 is a powder that, when mixed with water, causes a rapid increase in pH, leading to the precipitation of all dissolved heavy metals. C2 aids in the quick sedimentation of suspended precipitates, while Fenton’s catalyst is a fast-acting oxidizer that further purifies the water and removes odors, making it safe for irrigation and daily use.
According to Mr. Le Ngoc Khanh, Deputy Director of the Envipro Environmental Protection Center in Ho Chi Minh City: “With this treatment compound, the effectiveness is very clear. We hope this technology will be tested on the To Lich River. According to calculations, it will take only 7-10 days to complete the cleaning process, at a cost significantly lower than foreign technologies.“
