Abstract
Bioreactors and associated methods are provided herein including bioreactors capable of treating water contaminated with 1,4-dioxane. In certain embodiments, a bioreactor is disclosed and may include an adsorbent layer with a biofilm capable of metabolizing 1,4-dioxane and a screen disposed downstream of the adsorbent layer configured to retain detached biofilm.
Claims18
A bioreactor system comprising:
- a housing having an inlet and an outlet;
- at least one adsorbent layer which (i) comprises a biofilm comprising microbes capable of metabolizing 1,4-dioxane and (ii) is contained with the housing;
- and
- a first screen positioned downstream from the at least one adsorbent layer, wherein the first screen is configured to retain within the bioreactor any of the biofilm that becomes detached from the at least one adsorbent layer, and wherein the housing is configured to receive through the inlet a flow of an influent comprising water contaminated with 1,4-dioxane and the bioreactor is configured to be operated in a manner effective to discharge an effluent from the outlet, which effluent comprises water contaminated with 1,4-dioxane in an amount of less than 0.5 μg/L.
