摘要
Membrane fouling is a common phenomenon that limits the widespread application and acceptance of membrane bioreactors (MBRs) in the industry. It remains one of the most challenging issues facing further MBR development. There is, thus, a need to understand and control the fouling process during water filtration. Understanding the mechanism at which fouling is induced and subsequently develops may help to generate ideas at which membrane fouling can be alleviated by controlling certain parameters. This study aims to identify the parameters responsible for membrane fouling on the membrane surface, and relate them to actual lab-scale operating parameters of an MBR system so that we can minimise the effects of membrane fouling in MBRs system in the industry.
