Abstract
Exemplary embodiments describe apparatuses and related processes for improving mixing and sheer in a fixed film reactor. One process can include recycling at least a portion of a biogas product through at least one sparger below a fixed film zone in the fixed film reactor at conditions sufficient for mixing and sheering the film from an internal structure within the fixed film zone. Often, a cross-sectional area of the fixed film zone fills at least about 90% of a cross-sectional area of the fixed film reactor.
Claims33
An anaerobic fixed film reactor comprising:
- a fixed film packing media configured within a zone of a reactor and to allow biological media to anchor and grow, wherein a cross-sectional area of the zone fills at least about 90% of a cross-sectional area of the reactor;
- a manifold for receiving re-cycled biogas;
- and
- a plurality of spargers coupled to the manifold and configured for distributing the re-cycled biogas to wastewater below the fixed film packing media, wherein the spargers are further configured to output biogas at a flow rate ranging from 0.1 to 10 cubic meter per hour per square meter of a reactor, horizontal cross-section area for providing turbulence of the wastewater and avoiding formation of undisturbed pockets of the wastewater.
A process for distributing re-cycled biogas in an anaerobic fixed film reactor comprising:
- allowing biological media to anchor and grow on a fixed film packing media configured within a zone of a reactor, wherein a cross-sectional area of the zone fills at least about 90% of a cross-sectional area of the reactor;
- receiving re-cycled biogas at a manifold;
- distributing the re-cycled biogas to wastewater from a plurality of spargers coupled to the manifold and configured below the fixed film packing media;
- and
- outputting biogas at a flow rate ranging from 0.1 to 10 cubic meter per hour per square meter of a reactor, horizontal cross-section area to provide turbulence of the wastewater and avoiding formation of undisturbed pockets of the wastewater.
An anaerobic fixed film reactor comprising:
- a fixed film packing media configured within a zone of a reactor and to avow biological media to anchor and grow, wherein a cross-sectional area of the zone fills at least about 90% of a cross-sectional area of the reactor;
- a manifold for receiving re-cycled biogas;
- and
- a plurality of spargers coupled to the manifold and configured for distributing the re-cycled biogas to wastewater below the fixed film packing media, wherein the spargers are further configured to output biogas at a flow rate ranging from 1 to 100 cubic meter per hour per square meter of a reactor, horizontal cross-section area for creating shearing on the packing media to prevent clogging of the media.
