Abstract:
A continuous flow wastewater treatment system is disclosed. The system can include a main processing circuit comprising an anoxic entry zone and an aerobic exit zone. The system can include a granule-producing sidestream incubator. The sidestream incubator can include an inlet that receives a first portion of return activated sludge (RAS) processed by the aerobic exit zone, a sidestream anoxic zone, and a sidestream anaerobic zone that cooperate to process the first portion of RAS. The sidestream incubator can include an outlet that delivers the processed first portion of RAS to the anoxic entry zone. The sidestream incubator can include a RAS bypass pathway that bypasses the granule-producing sidestream incubator to deliver a second portion of RAS processed by the aerobic exit zone to the anoxic entry zone. In some embodiments, the RAS and/or other fermentate can be step-fed into the sidestream incubator.
