Abstract Details

2011, Master of Science in Engineering, University of Akron, Civil Engineering.
Dissolved organic carbon (DOC) poses many challenges for drinking water treatment plants (WTP) as its reaction with chlorine produces disinfection by-products (DBP) which are undesirable because if their harmful effect on humans and is also regulated by the United States Environmental Protection Agency (U.S. EPA). Parallel factor (PARAFAC) analysis, fluorescence regional integration (FRI), excitation-emission matrices (EEM) maximum peaks and ultra-violet absorbance (UVA) are all optical analysis methods used to characterize DOC and its contribution to disinfection by-product (DBP) formation. Multifactor linear regression models were developed from these optical analysis methods to predict DOC concentrations and DBP formation from raw water and coagulated water collected from a WTP. This comprehensive study utilized 492 total samples collected from January 2010 to July 2011that were used in the DOC analysis while 88 total samples (September 2010 to July 2011) were used for the DBP analysis. The models were evaluated statistically to determine which of the optical analysis techniques performed the best in predicting DOC concentration and DBP formation. PARAFAC analysis had the highest linear correlations of all the models tested and had statistically significant components characterizing the nature of DOC and the precursors to DBP formation. The speed, sensitivity and low cost of PARAFAC analysis shows great promise for incorporation of PARAFAC components into a WTP operation helping them make more informed and science-based decisions to treatment train processes.
