Cake formation of bidisperse suspensions in dead-end microfiltration by Han, Qi, Trinh, Thien An, Chew, Jia Wei

“…The evolution of the cake during dead-end microfiltration of different compositions of bidisperse feeds was investigated using network modeling and three-dimensional (3D) optical coherence tomography (OCT) imaging. The foulant particles were latex of two different sizes (namely, 3 and 5 µm) and the membrane was polycarbonate track-etched with nominal diameter of 2 µm. …”

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. …”

Towards indicating human skin state in vivo using geometry-dependent spectroscopic contrast imaging by Ni, Guangming, Ge, Xin, Liu, Lin, Zhang, Jing, Wang, Xiangzhou, Liu, Juanxiu, Liu, Linbo, Liu, Yong

“…We previously reported on geometry-dependent spectroscopic contrast achieved by spectroscopic micro-optical coherence tomography (SμOCT), which discovered that transversely oriented and regularly arranged nano-cylinders selectively backscatter the long-wavelength lights and generate spectral centroid (SC) shifts towards the long wavelengths within a spectral window of 700 - 950 nm. …”

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).…”
