Fouling rate

In BF-MBR, as in all sMBR systems, sufficient aeration is necessary to maintain local cross-flow conditions for sustainable membrane operation. Aeration rate is normally based on previous experiences and manufactures’ recommendations. BF-MBR with an external submerged membrane unit, designed only fo

Fouling is still one of the major issues of the membrane bioreactor (MBR) research. Most attention is currently paid to extracellular polymeric substances (EPS) in either bound or soluble/colloidal (soluble microbial products, SMP) form. While several trends or correlations were reported, the compar

Extracellular polymeric substances (EPS) are considered as the major cause of membrane fouling in membrane bioreactors. Recent studies have revealed a linear relationship between fouling rate (increase of filtration resistance over time) and polysaccharide (PS) concentration [1]. Several factors lik
