Interaction between biology and membranes in membrane bioreactors

Ziel

"Membrane bioreactors are a promising technology for wastewater treatment and reuse. Membrane fouling is inherent to their operation and seems to be affected by the composition of the sludge. In this fellowship the relation between biology and membrane fou ling will be studied from three perspectives: the determination of slime materials produced by the sludge, the microbial community composition of the sludge with special emphasis on the presence of slime-producing organisms and the development of a fouling measurement method which allows studying the process and mechanisms of membrane fouling. The latter has been developed by the host institute for non-biological membrane filtration applications and will now be upgraded for MBRs. The proposal goes beyond t he state of the art by analyzing the relationship between biochemical sludge characteristics and membrane fouling for a wide range of operational conditions, wastewaters and MBR systems. It is highly innovative since no reports are known that try to find a relation between the composition of the microbial community in a MBR, the presence of specific organisms that may contribute to slime production, and membrane fouling. Finally, the combined approach of biochemical analysis, microbial monitoring and applic ation of a new and versatile fouling measurement method with the purpose of studying fouling phenomena is completely new for this application. The derived information and relationships must allow adjusting MBR operation in such a way that membrane fouling is minimised. This results in a lower frequency of membrane cleaning and an increased membrane lifespan. The reduced operational cost will enhance MBR application for wastewater treatment and water reuse. The fellow has the background and the host insti tute has the infrastructure and the supporting team to make this multidisciplinary proposal a success."
