Polar natural organic matter (NOM) is usually predominantin conventionally-treated and finished drinking waters. The polar NOM has shown potential to form disinfection byproducts (DBPs). Utilities may be able to utilize advanced processesto optimize their treatment for the removal of polar and nonpolar NOM and thus control DBP formation in drinking water. Systematically, full-scale conventionally-treated samples were subjected to bench-scale activated carbon adsorption, ultrafiltration membrane, and ozonation/biotreatment processes to assess the potential removal of NOM. Dissolved organic carbon (DOC) characterization and DBP characterization analyses were performed on bench-scale untreated and treated samples to better understand the factors and processes that can control polar NOM removal and corresponding DBP reductions.
