Continuous batch activated sludge process (hereinafter abbreviated as 'SBR process'), one of the water treatment methods, performs the functions of aeration, sedimentation and discharge in one reactor.

In general, SBR-based water treatment facilities are used for symbolic water discharge devices such as buoyancy, hydrologic, pump, or rock type to discharge the symbol water. However, they are not universal because they are local and limited in accordance with their own SBR method. In addition, the spatial separation of the aeration tank and sedimentation tank over time is essential in implementing a water treatment facility of the SBR method. This SBR method discharges the symbolic water compared to the A2O-based method, in which a sewage tank composed of the overflowware is configured separately. This somewhat unstable element exists. For example, sludge loss may occur in the settling and discharge stages.
