Despite receiving a Revised 28 4 2022 lot of attention and investment from all levels and sectors and although Published 11 5 2022 many domestic and foreign projects have been implemented the results have not been as expected. To contribute to the mitigation of river water KEYWORDS pollution we conduct the research on treament of To Lich River water by using Sagi Bio 2 biological product. The use of biological products will To Lich River limit the impacts on humans and the environment compared to Pollution conventional chemical treatment measures. The study carried out several Biological product actual sampling and treatment at laboratory-scale. The analysis results showed that To Lich River water has been heavily polluted. The study Sagi Bio2 conducted experiments to treat To Lich River water using the biological COD product with a dosage of 2 ml L in the condition of no aeration achieving a good result. COD concentration reduced by 90 meeting the standard. Although Phosphate concentration was still over the standard it reduced about 41 . Nitrat concentration before treatment was under the standard and tended to reduce after treatment.
