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.
Claims20
A bioreactor system comprising:
- a housing having an inlet and an outlet;
- at least one adsorbent layer which (i) comprises a biofilm comprising microbial inoculum 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 has a plurality of openings having a largest dimension of about 0.001 mm,
- wherein the first screen is configured to retain within the housing any of the biofilm and microbial inoculum 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.
