Wastewater Technology Fact Sheet: Sequencing Batch Reactors

Sequencing Batch Reactors DESCRIPTION The sequencing batch reactor (SBR) is a fill-and-draw activated sludge system for wastewater treatment. In this system, wastewater is added to a single “batch” reactor, treated to remove undesirable components, and then discharged. Equali zation, aeration, and clarification can all be achieved using a ...
