Session Keynote
You don’t have to do it alone: Combined technologies for treating 1,4-dioxane and co-contaminants

1,4-Dioxane is a synthetic industrial chemical that is highly soluble in water and is (still) considered to be an emerging water contaminant. The occurrence of 1,4-dioxane in water supplies is hazardous to humans because 1,4-dioxane is classified as a probable carcinogen. Even though there are no U.S. federal regulations for the maximum contaminant levels of 1,4-dioxane in drinking water yet, several states have promulgated local health advisory levels. As a result, removing this contaminant from water is an area of great interest, leading to several recent advances in destructive and non-destructive technologies. Design and engineering of novel treatment trains for 1,4-dioxane is most promising in order maximize the effectiveness of field solutions or potable reuse systems by creating synergisms between the benefits of the different applied technologies. Combined treatments may include different configurations of oxidation/electrochemical treatments, catalysis, adsorption, photolysis, and biodegradation. These treatment trains achieve greater removals and may therefore facilitate successful remediation more than their individual component technologies likely could.
