Description
This powerpoint presentation begins by providing an outline of the presentation that includes the following: ClO<sub>2</sub> and its byproducts in distributionsystems;occurrence of ClO<sub>2</sub>, ClO<sub>2</sub><sup>-</sup> and ClO<sub>3</sub><sup>-</sup>;fate of ClO<sub>2</sub>, ClO<sub>2</sub><sup>-</sup> and ClO<sub>3</sub><sup>-</sup>;effect of ClO<sub>2</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 ClO<sub>2</sub> in distributions systems;decrease with increasing water age whenClO<sub>2</sub> is used as residual disinfectant;ClO<sub>2</sub> may reform in presence of Cl<sub>2</sub>;fate of ClO<sub>2</sub><sup>-</sup> in distributions systems;variable, no trends;decrease with increasing water age; fate of ClO<sub>3</sub><sup>-</sup> in distribution systems;generally stable when ClO<sub>2</sub> is used asresidual disinfectant;increase in presence of Cl<sub>2</sub>; formation of offensive odors atcustomers’ houses when ClO<sub>2</sub> is used asresidual disinfectant;successful cases;variable effects of ClO<sub>2</sub> on biomass; may help control nitrification;effects of ClO<sub>2</sub> on corrosion:may not promote corrosion anymore than Cl<sub>2M/sub>or monochloramine;corrosion byproducts reduce ClO<sub>2</sub> into ClO<sub>2</sub><sup>-</sup>,then Cl<sup>-</sup>. Includes tables, figures.
