Aerobic SBR's (Sequence Batch Reactor) are unique activated sludge configurations distinguished by their repeating sequence of fill, react, biomass settling, and effluent withdraw which all occur within one tank.
Advantages of SBR's in comparison to conventional activated sludge include elimination of final clarifiers and return sludge pumping; ease in making operational changes to fine-tune nutrient removal; ability to hold
and test treated wastewater before release; and flexibility in adjusting reaction times and tank volumes to meet variable loadings.
