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