The sequencing batch reactor is a specific fill‐and‐draw version of the activated‐sludge process. In contrast to the continuous‐flow alternative, metabolic reactions and solid‐liquid separation are carried out in one tank and in a well‐defined and continuously repeated time sequence. This paper reviews the historical development of sequencing batch reactor technology and describes the different modes of operation. Mass‐balance equations are introduced to allow for a quantitative comparison of sequencing batch reactor and continuous‐flow technologies and for the design of such systems. The initial design dynamic simulation and in‐situ adjustment of the cycle program under the actual process conditions can be used conveniently to further optimize the sequencing batch reactor plant.
