Sequencing Batch Reactor (SBR) Systems

Sequencing Batch Reactor (SBR) systems are advanced, fill-and-draw activated sludge processes designed to treat municipal and industrial wastewater in a single tank. By performing equalization, aeration, clarification, and decanting in timed sequences, SBRs deliver high treatment efficiency within a compact footprint allowing for flexible operation.

For more than 40 years, Xylem has helped municipalities and industries overcome wastewater treatment challenges through proven true-batch and continuous fill SBR designs.  Today, our systems reliably treat flows ranging from 0.01 to more than 60 million gallons per day (MGD). Our design flexibility allows engineers to meet unique project requirements, while the simplicity of operation puts plant operators at ease.
