Abstract
Both the proposed United States Environmental Protection Agency (USEPA) Disinfectant/Disinfection By-Product and Interim Enhanced Surface Water Treatment rules have provisions for minimizing the formation of undesirable disinfection by-products (DBPs) in drinking water. Natural organic matter (NOM) in natural waters contains many of the precursors to the DBPs formed following disinfection of drinking water. Resin adsorption procedures were used to isolate and fractionate NOM into six dissolved organic matter (DOM) fractions; Hydrophobic acid (FA), base (FB), neutral (FN), and hydrophilic acid (PA), base (PB), and neutral (PN). Aluminum sulfate (alum) jar coagulation tests were performed over a range of pH and alum dosages to determine the maximum removal of each fraction within that range.
