This presentation looks at Chlorine Dioxide’s potential as the new primary disinfection for the 21st century. We’ll explore this disinfectant by 1st comparing the common forms of Chlorine, then we’ll look at very basic chemistry to determine why Chlorine Dioxide has terrific potential as a replacement. We’ll explore common uses today, some of the key difference/advantages Chlorine Dioxide offers operators when disinfecting our potable waters and treated wastewater effluents. With today’s high transportations costs perhaps it’s time to look at site-generation of our primary oxidizers. Chlorine Dioxide may prove to be the disinfectant of choice to minimize byproducts, maximize disinfectant residuals, at predictable costs. This presentation looks at Chlorine Dioxide’s potential as the new primary disinfection for the 21st century.

Learning Objectives
1) Basic understanding how Chlorine dioxide is produced, handling, safety, storage, etc.
2) Learn why Chlorine Dioxide reactions in water and wastewaters are so unique the only chlorine-based oxidizer that does not hydrolyze.
3) Potential applications in both water and wastewaters for disinfecting as well as minimizing byproducts.
