The recent advances in research microbial cultures with faster dioxane degradation rates and adsorbents with higher capacity have provided an opportunity to evaluate the effectiveness of dioxane biofiltration.

The concentrations in the industrial wastewater are typically on the order of 0.1 to several mg/L, and the potential wastewater discharge limits are likely in the range of 1 to 200 μg/L or lower. This paper describes the ongoing proof-of-concept bench testing of dioxane biofiltration in synthetic wastewater containing up to 500 μg/L of dioxane. A newly discovered dioxane-degrading culture exhibiting uniquely rapid degradation kinetics at environmentally relevant concentrations was tested. Types and properties of the adsorbent and the addition of a structural analogue to enhance dioxane biodegradation were evaluated.
