Destruction of 1,4-Dioxane in Water

Location: Region 2 | Published: July 07, 2023

ecoSPEARS conducted two (2) separate experiments to evaluate the efficiency of the ecoCUBE UV destruction technology against 1,4-dioxane.

Experiment A: In-House Synthesized Sample

This in-house study aimed to evaluate the effectiveness of the ecoCUBE UV technology in treating water contaminated with 1,4- dioxane. Synthesized samples of 100 PPB 1,4-dioxane water were treated and analyzed at 5 minutes, 1 hour, and 8 hour intervals. The results revealed that UV light alone was ineffective in reducing the concentration of 1,4-Dioxane. However, when UV light was combined with Advanced Oxidative Process additives, significant effectiveness was observed. The maximum reduction of 99.67% occurred within the first 5 minutes of exposure.

Experiment B: Client-Provided Sample

In collaboration with a client, ecoSPEARS conducted a study on water samples contaminated with 1,4-dioxane to evaluate the efficacy of the ecoCUBE in degrading 1,4-dioxane within unfiltered groundwater samples. The study utilized AOP (Advanced Oxidative Process) additives in conjunction with Ultraviolet (UV) light to enhance the degradation process. UV-light with the AOP additives exhibited a substantial rate of 1,4-dioxane destruction, resulting in a significant reduction of approximately 60% in 1,4- dioxane concentrations after five minutes of exposure. These findings indicate that the UV-catalyzed AOP reaction can effectively destroy 1,4-dioxane, estimating a 99% destruction after 10 minutes, based on a linear estimate model or a timeframe between 20 to 25 minutes using an exponential model.
