Wastewater Technology Fact Sheet: Sequencing Batch Reactors
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. SBR systems have been successfullyused to treat both municipal and industrialwastewater.
systems are flowrate, BOD5, TSS, and Fecal Coliform. In addition, many states are moving toward requiring nutrient removal. Therefore, total nitrogen (TN), TKN, NH 3-N, or TP may also be required. It is imperative to establish effluent requirements because they will impact the operating sequence of the SBR. For example, if there is a
