Abstract. The sequencing batch reactor (SBR) is a specific fill and draw version of the conventional activated sludge (AS) process. In contrast to continuous flow systems, the sequencing of batch processes in the SBR is time rather space oriented; metabolic reaction and solid/liquid separation take place at different times in the same reactor.
