Fouling and mitigation mechanisms during direct microfiltration and ultrafiltration of primary wastewater by Hube, Selina, Wang, Jingwei, Sim, Lee Nuang, Ólafsdóttir, Dagmar, Chong, Tzyy Haur, Wu, Bing

“…Several types of MF and UF membranes were examined by threshold flux determination, and two types of membranes (MF, 0.08 μm; UF, 100 kDa) were chosen for exploring membrane fouling mechanisms at different feed pressures via both fouling resistance analysis and optical coherence tomography (OCT) observation. The results revealed that both MF and UF displayed three-stage fouling behaviors, i.e., initial intermediate pore blocking followed by two-stage cake filtration. …”

A network-based approach to interpreting pore blockage and cake filtration during membrane fouling by Han, Qi, Li, Weiyi, Trinh, Thien An, Liu, Xin, Chew, Jia Wei

“…Although limited fouling cases were examined in the current study, it is expected that the network model developed here can be readily applied to study more complex phenomena involved in a membrane filtration process (e.g., shear-induced diffusion), and the associated insights would be significantly enhanced when coupled with more advanced fouling characterization techniques (e.g., Optical Coherence Tomography).…”
