Toelichting (Engels) Membrane (ultra)filtration of activated sludge from membrane bioreactors (MBR) is usually performed with low fluxes. This is done to prevent membrane fouling and system failure. However, even when operated with low fluxes, filterability of the biomass can fluctuate in time considerably. Among the many causes that are mentioned to explain this phenomenon, changes in influent quality and quantity seem most probable. Until now, only little work was done to quantify effects of transient conditions in feeding pattern of an MBR. This paper describes experiments in which 25 L samples of the biomass from an MBR system were fed with an easily biodegradable carbon source. The filterability of the biomass was monitored with standardised filtration characterisation measurements. Along with filtration characterisation the water phase of the activated sludge was analysed for extracellular polymeric substances (EPS)

To support researchers to publish their research Open Access, deals have been negotiated with various publishers. Depending on the deal, a discount is provided for the author on the Article Processing Charges that need to be paid by the author to publish an article Open Access. A discount of 100% means that (after approval) the author does not have to pay Article Processing Charges.

For the approval of an Open Access deal for an article, the corresponding author of this article must be affiliated with Wageningen University & Research.
