Full Description

This powerpoint presentation begins by providing an outline of the presentation that includes the following: ClOsub2/sub and its byproducts in distributionsystems;occurrence of ClOsub2/sub, ClOsub2/subsup-/sup and ClOsub3/subsup-/sup;fate of ClOsub2/sub, ClOsub2/subsup-/sup and ClOsub3/subsup-/sup;effect of ClOsub2/sub on water quality;tastes and odors;natural organic matter (NOM), biomass, and nitrification; and,corrosion. Presentation summary and conclusions indicate the following:fate of ClOsub2/sub in distributions systems;decrease with increasing water age whenClOsub2/sub is used as residual disinfectant;ClOsub2/sub may reform in presence of Clsub2/sub;fate of ClOsub2/subsup-/sup in distributions systems;variable, no trends;decrease with increasing water age; fate of ClOsub3/subsup-/sup in distribution systems;generally stable when ClOsub2/sub is used asresidual disinfectant;increase in presence of Clsub2/sub; formation of offensive odors atcustomers' houses when ClOsub2/sub is used asresidual disinfectant;successful cases;variable effects of ClOsub2/sub on biomass; may help control nitrification;effects of ClOsub2/sub on corrosion:may not promote corrosion anymore than Clsub2M/subor monochloramine;corrosion byproducts reduce ClOsub2/sub into ClOsub2/subsup-/sup,then Clsup-/sup. Includes tables, figures.
