The demand for safe and clean drinking water has rapidly increased, due to population growth and global industrialization. Furthermore, the limited freshwater sources are polluted by receiving large amounts of wastewater generated by municipalities and various types of industries. Thus, advanced wastewater purification technologies are highly desirable for environmental protection. Aerobic membrane bioreactor (AeMBR), a relatively new and advanced technology, has been widely used for both municipal and industrial wastewater treatment globally but has to compete with the conventional biological wastewater treatment technologies, such as activated sludge processes, for the market. The evolution of the AeMBR technology calls for further studies to improve process efficiency, energy consumption, process design, and optimization of process operation. The proposed study aims to improve and optimize AeMBR process design and operation by studying the biological and membrane behaviours of AeMBR under process conditions and using machine learning (ML) for advanced membrane fouling control. It is anticipated that the outcomes of this study will fill the knowledge gaps of AeMBR under short solids retention time and hydraulic retention time and develop modelling tools to improve process design and operation. The success of this study will develop a new AeMBR design manual, expand the market of AeMBR technologies, and develop the next generation of AeMBR technologies, and promote the Canadian wastewater purification technologies for applications all over the world.
