The SBR technology, the Sequencing Batch Reactor process (abbreviated SBR procedure) is a variation of the conventional activated sludge process. The SBR consists of a reaction chamber which first operates as a biological reactor and then as a sedimentation chamber.
SBR technology and functional principle – SBR = Sequencing Batch Reactor
Unlike reactors where the wastewater flows through continuously, the SBR is filled and emptied discontinuously. The conventional physical separation of the biological processes and the sedimentation is replaced by a chronological one. The time interval from the beginning of the filling process until the end of the clearwater drainage and a possible phase of rest is one cycle.
