prechlorination การใช้

• The effect of prechlorination on powdered activated carbon for removing odor
• However , although prechlorination efficiently removed algae , its effect was directly related to the quantity of algae and was more obvious in the period of algae bloom . with regard to yellow river water in winter with low temperature and low turbidity , it was discovered that preozonation did not result in a substantial removal of total organic carbon ( toc ) , but a remarkable uv254 . it was further revealed that preozonation changed the characteristics and structure of organic matters and then enhanced removal efficiencie s of them by subsequent processes
• The enzyme - linked immunosorbent assay ( elisa ) and high performance liquid chro - matography ( hplc ) analysis for detection of mc were optimized . the removal rates of mc by conventional water treatment processes were investigated through the laboratory study and the detection of mc in every process in meiyuan drinking water treatment plant . results showed that the prechlorination of eutrophic water led to the release of intracellular toxins to water phase
