Full Description
This powerpoint presentation begins by providing a brief overview of the sources and health effects of 1,4-Dioxane. Treatment process effectiveness is presented, along with the bench scale treatment process train:lime softening,ozone,BAC, andchloramines. The bench scale treatment method is presented, along with the impact of initial dioxaneconcentration andtemperature, a cost comparison of50% 1,4-Dioxane removal vs 90% 1,4-Dioxane removal, greenhouse gas emissions comparison of50% 1,4-Dioxane removal vs 90% 1,4-Dioxane removal. Presentation summary: 1,4-Dioxane is difficult to remove fromwater;UV/Hydrogen peroxide is effective, butenergy intensive; and,ozone followed by biological filtration isan economical removal method, and moresustainable.
