Haloacetic Acid (HAA) Precursor Treatment: Identifying Characteristics for Removal
Conference Proceeding by American Water Works Association, 11/01/2007

Document Format: PDF

Description

The objectives of this study were to treat eight natural organic matter (NOM) surrogates and one treateddrinking water using four different processes, and to quantify the impact upon formation of Haloacetic Acids(HAAs). Of the surrogates, four are amino acids (glutamic acid, glycine, leucine and serine); twoare monosaccarides (mannose and xylose) and two phenolic (resorcinol and tannic acid).The focus is on hydrophilics as these types of molecules are less responsive toconventional treatments. The treatments are UV-C, biologically-active sand and twoadvanced oxidation processes (AOPs): vacuum UV (VUV) and UV-H<sub>2</sub>O<sub>2</sub>. Since theyremove NOM by differing mechanisms, it can be expected the treatments will interactwith the surrogates in various ways and consequently affect HAA formation potential(HAAFP). Includes 17 references, tables, figures.
