Impacts of Sludge Volume and Sludge Age on Disinfection By-Product Formation in a Full-Scale Water Treatment Facility
… samples were tested for trihalomethanes and haloacetic acids at both ends of the sedimentation process to evaluate formation over the length of the basin. Sludge volume and other important water quality parameters were also measured at the time of sample collection. Statistical analyses were …

Removal of disinfection by-product precursors by activated carbon and MIEX(R)
The objective of this research was to investigate NOM removal with activated carbon and MIEX(R). Hydrophilic (HPI), hydrophobic (HPO), and transphilic (TPI) NOM was fractionated and subsequent DBP formation from these fractions was studied. Several new adsorptive materials (greensand, carbon …

The Effect of Natural Organic Matter on UV/H<sub>2</sub>O<sub>2</sub> Treatment and the Effect of UV/H<sub>2</sub>O<sub>2</sub> Treatment on Natural Organic Matter
… impact on trihalomethane (TTHM) and haloacetic acid (HAA5) formation potential, and evaluated UV/H<sub>2</sub>O<sub>2</sub> effects on TTHM speciation after chlorination. Granular activated carbon (GAC) adsorption was investigated to improve process efficiency and reduce by-product …

Fluorescence Based Approach to Drinking Water Treatment Plant Natural Organic Matter (NOM) Characterization, Treatment, and Management
… compared with the degree of fitting when the haloacetic acid formation potential (HAAFP) was analyzed. PARAFAC components with humic-like nature showed to be closely associated with THMFP and HAAFP, while structures with protein-like nature exhibited weak association with DBPFP and …

The Occurrence and Control of Disinfection By-Products (DBPs) in Two Water Treatment Plants Utilizing the Same Source
… which the majority produced by chlorination were haloacetic acids (HAAs), within the HAAs, dichloroacetic acid (DCAA) and trichloroacetic acid (TCAA) were the dominant members. Concern over potential health effect led the U.S. Environmental Protection Agency (USEPA) to set a maximum contaminant …
