Disinfection By-Products Formation After Coagulation Of Algal Extracellular And Intracellular Organic Matters, Tianyiru Chen
Electronic Thesis and Dissertation Repository
Algal organic matter (AOM) is found in high concentration during algal bloom season in drinking water systems, which is generally categorized into extracellular organic matter (EOM) and intracellular organic matter (IOM). These compounds are not well removed in traditional water treatment methods such as coagulation, and are the precursors of subsequent disinfection by-products (DBPs) during chlorination of water. In this study, EOM and IOM content of four different algae were quantified measuring dissolved organic carbon (DOC), UV absorbance at 254 nm and turbidity. Coagulation using alum (Al2(SO4)3•16H2O)was used to remove the algal …
