ABSTRACT:
A multi-channel vertical shaft bioreactor having a downcomer; a riser operatively in communication with the downcomer to form a loop; an off-gas head tank; a part of the loop being through the head tank; a de-gassing plate around which effluent liquor is de-gassed to produce a de-gassed liquor and an off-gas receivable by the head tank; oxygen containing gas injection means for injecting gas into the riser; liquid influent injection means to inject influent into the riser; means to extract liquid effluent from the bioreactor; the improvement comprising one or more vertical baffle plates disposed within an upper part of the head tank to define a plurality of off-gas receiving chambers; a plurality of biofilters, a plurality of off-gas conduits in communication with the chambers and the biofilters to operably allow passage of off-gas from the chambers to the biofilters to effect off-gas aeration in the biofilters; and conduit off-gas controls for the treatment of waste water. Each of the multiple gas confinement compartments in the single head tank can operate at different pressures and enable each of the biofilters to be independently back-washed.
