“Sequencing-Batch-Reactor”, known abbreviated as “SBR”, is an important technology used in water treatment systems. In this process, purely biological wastewater treatment is carried out with activated sludge.
Activated sludge consists of microorganisms that decompose pollutants dissolved in wastewater. The wastewater treatment processes in SBR do not occur in a spatially separate manner, but in a chronological order (“treatment cycle”). The incoming wastewater is collected in a buffer, cleaned in portions and discharged in a targeted manner at the end of a treatment cycle. Equalization, aeration and purification processes can be performed using a single reactor.
Since all treatment steps are done in the same tank, SBR systems require less space compared to conventional treatment systems. The system capacity is determined depending on the flow rate of the wastewater and the pollution load.
