Filtration properties of sEPS gel layer. (A) Flux profiles as a function of filtration time at constant pressure (0.2 bar) of the sEPS with low PS:PN ratio (anaerobic, grey line) and high PS:PN ratio (aerobic, black line). A formation (I) and operational phase (II) are indicated. The data profile was obtained from the triplicate filtration experiment (Replicates are shown in Supplementary Figure S1). (B) Final filtration resistances of the layers.

Soluble Extracellular Polymeric Substances (sEPS) are a mixture of microbial soluble polymers produced during aerobic or anaerobic treatment of wastewater. Gel layers mainly consisting of sEPS are usually present in the fouling layers of membrane bioreactors (MBRs) and in the dynamic membranes (DMs) of dynamic membrane bioreactors (DMBRs), and thei...
