 <\/p>\n

The presence of 1,4-Dioxane in water sources has gained the attention of regulating bodies and the media recently. \u00a0Recent advances in analytical tools have given confirmation of the presence of 1,4-Dioxane in groundwater and drinking water sources, along with common sources or related contaminates. \u00a0 This, along with the better understanding of the potential health effects of 1,4-Dioxane has created additional pressure at the removal of this VOC from drinking water and potentially contaminated groundwater sites.<\/span><\/p>\n

 <\/p>\n

Ozone may be the answer or a part of the answer to 1,4-Dioxane removal in water.<\/span> \u00a0Our recent bench tests<\/a> found complete elimination of 1,4-Dioxane in water within 10 minutes of treatment time. \u00a0Adding\u00a0H2O2 to achieve the Advanced Oxidation Process (AOP) showed no benefit\u00a0to ozone alone.<\/span><\/p>\n

This data showed complete elimination of 1,4-Dioxane with ozone, along with reduction of all other VOC’s present in water at the same time. \u00a0<\/span><\/p>\n

We have provided equipment for removal of VOC’s and specifically 1,4-Dioxane from drinking water and contaminated groundwater plumes. \u00a0Should you require specific equipment recommendations, we would be pleased to discuss this with you. \u00a0<\/a><\/p>\n
