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.

由于人口增长和全球工业化，对安全和清洁饮用水的需求迅速增加。此外，有限的淡水资源因接收市政当局和各类工业产生的大量废水而受到污染。因此，先进的废水净化技术对环境保护是非常可取的。好氧膜生物反应器（AeMBR）是一项相对较新的先进技术，已在全球范围内广泛应用于城市和工业废水处理，但在市场上与传统的生物废水处理技术（如活性污泥法）存在竞争。AeMBR技术的发展需要进一步研究以提高工艺效率、能耗、工艺设计和工艺运行优化。本研究旨在通过研究AeMBR在工艺条件下的生物和膜行为，并利用机器学习（ML）进行高级膜污染控制，改进和优化AeMBR工艺设计和运行。预计本研究的结果将填补短固相滞留时间和水力滞留时间下AeMBR的知识空白，并开发建模工具来改进工艺设计和操作。该研究的成功将开发新的AeMBR设计手册，扩大AeMBR技术的市场，开发下一代AeMBR技术，并将加拿大废水净化技术推广到世界各地。
