TL;DR: In this article, six independent research projects are presented, starting from different angles, all groups finally ended up analysing the organic fraction in the effluent and activated sludge supernatant, respectively.

TL;DR: In this paper, the results of applying the mentioned filtration characterisation method at three membrane bioreactors (MBR) pilot locations in the Netherlands were described. But the results were sustained by EPS analyses in the water phase of the respective activated sludge broths.

TL;DR: Different ways of separating the water phase from the biomass are investigated, where a simple filtration over a paper filter turned out to be sufficient and a simple batch test set up was used to investigate the influence of substrate conditions on the amount of EPS in the waterphase.

TL;DR: Both potentials and limits of biomass–membrane interactions are reviewed with a focus on recent results from Europe, especially from Germany.

TL;DR: Activated sludges from different MBR-pilots react differently in terms of filterability development, and the addition of acetate improved the filterability of the biomass, whereas the EPS concentration in the water phase increased.
