A Review on Sequencing Batch Reactors: Process Design, Operation and Modelling

Authors: Rasheed AA, Ciroma SI


The sequencing batch reactor (SBR) is perhaps one of the most promising of the activated sludge process modifications today for the removal of both organic matter and nutrients. The SBR differ from conventional continuous-flow activated sludge plants because they combine all the treatment steps and processes into a single tank, thereby eliminating the need of multiple units. Holistic design of the process and optimisation of the operating parameters is still a major issue of concern due to its transient nature of operation. Most of the studies on modelling the SBR are selective, aimed at either optimising the operation of existing treatment units to determine optimal operational policies, or finding the optimum filling strategy or time sequences and scheduling. This research presents a literature review specific to wastewater treatment using SBRs. This review discusses fundamental aspects of aerobic SBR process and operation; design and operating parameters of SBR processes; process modelling and optimisation of the SBR processes.
