This powerpoint presentation begins by providing a brief overview of the formation of organic chloramines and their role in causing water quality problems. The objective of this study was to understand the reactions between free chlorine and monochloramine with microbes/their related materials, focusing on the formation of organic chloramines and their associated biocidal efficacy. Materials and methods included: Extracellular Polymer Substances (EPS) extraction; Heterotrophic Plate Count (HPC) Bacteria preparation; organic chloramines formation experiments; and, inactivation studies. Presentation conclusions indicate the following: organic chloramines can be formed by a reaction between disinfectants and microbe/their related materials (e.g., EPS and planktonic bacteria) in the distribution systems; organic chloramines produced from EPS and cell surfaces give total DBP colorimetric responses; organic chloramines may remain on/within the biomass, not "solubilize" into solution; and, since formed organic chloramines do not have inactivation efficacy, the formation of organic chloramines may cause the water quality problem in the distribution system.
