Abstract

Natural organic matter (NOM) and halides (Br- and I-) present in source waters react with disinfectants to formdisinfection by-products (DBPs). Current coagulation and adsorption techniques used in drinking water treatmenthave good NOM removal capacity, but have low halide removal capacity. This is due primarily to the presence ofcompeting anions in solution, such as bicarbonate, and components of NOM itself. This project aims to understandthe relationship between the NOM:halide ratio and specific DBP formation, since removing NOM alone in a highbromide/iodide source water may lead to high brominated/iodinated DBP formation. In addition, this work will studythe effectiveness of several adsorptive techniques on NOM and halide removal under controlled conditions. This willdetermine the conditions that are advantageous for use in DBP precursor removal and lowering subsequent DBPformation upon disinfection
