Modelling anaerobic biomass growth kinetics with a substrate threshold concentration \ Water research : the journal of the International Association on Water Quality [Artikel]
Ribes, J. \ Keesman, K. \ Spanjers, H. \ 2005
Many bacteria have been observed to stop growing below a certain substrate threshold concentration. In this study, a modification of the Monod kinetics expression has been proposed to take into account this substrate threshold concentration observed ...

Pulse shear stress for anaerobic membrane bioreactor fouling control \ Water science and technology : a journal of the International Association on Water Pollution Research [Artikel]
Yang, J. \ Spanjers, H. \ Lier, J.B. van \ 2011
Increase of shear stress at membrane surfaces is a generally applied strategy to minimize membrane fouling. It has been reported that a two-phase flow, better known as slug flow, is an effective way to increase shear stress. Hence, slug flow was intr ...

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.
