United StatesEnvironmental ProtectionAgencyOffice of WaterWashington, 932-F-99-073 September 1999 WastewaterTechnology Fact SheetSequencing Batch ReactorsDESCRIPTIONThe Sequencing Batch reactor (SBR) is a fill-and-draw activated sludge system for wastewatertreatment. In this system, Wastewater is added to asingle Batch reactor, treated to removeundesirable components, and then , aeration, and clarification can all beachieved using a single Batch reactor. To optimizethe performance of the system, two or more batchreactors are used in a predetermined sequence ofoperations.
suspended solids (TSS) or biochemical oxygen demand (BOD) are greater than 400 to 500 mg/L. Historic data should be evaluated and the SBR manufacturer consulted to determine whether primary clarifiers or equalization are recommended prior to an SBR for municipal and industrial applications. Equalization may be required after the SBR,
