In situ 3D characterization of monodispersed spherical particle deposition on microsieve using confocal laser scanning microscopy

A multiscale approach to study dead end microfiltration of mono and bidispersed particle suspensions

“…N p is an order lower than N 0 which gives an estimating fraction of open pores α 2 very close to the one calculated theoretically. In this case, the increase in cake resistance expressed by R C / R m , remains low which confirms the mechanisms of pore blocking and pore protection discussed in a previous paper …”

“…The following particles were either deposited over still accessible opened pores or intercepted by the previously deposited particles. Theoretical schematic representations of the two size particles, as well as the remaining open pores after the deposition of the first particles, were extensively discussed in a previous work . According to these results, the organization of the first arriving particles mainly depends on their size as well as the geometrical properties of the membrane.…”

In situ observation of the growth of biofouling layer in osmotic membrane bioreactors by multiple fluorescence labeling and confocal laser scanning microscopy

“…CLSM also allows the observation of a selected plane at a given depth (Yun et al, 2006;Meng et al, 2010;Hassan et al, 2014). It could be used for analyzing the development of fouling layer through observing the images at different distance from the FO membrane surface, which provides complementary information to the temporal development over time reported in the earlier sections.…”

“…Currently, one of the best approaches for nondestructive in situ examination of biofilm is the application of fluorescent probes (Yun et al, 2006;Yu et al, 2011). Many researchers have pointed out that CLSM combined with multiple fluorescence labeling is a powerful tool for investigating the structure, distribution and function of biofilm constituents at the microscale (Yun et al, 2006;Meng et al, 2010;Dominiak et al, 2011;Wang et al, 2012b;Hassan et al, 2014;Linares et al, 2014). Thus, the objective of this study is to in-situ investigate the growing mechanisms of the biofouling layer on the FO membrane surface in the OMBR by multiple fluorescence labeling and CLSM.…”

Removal of bacteria and yeast in water and beer by nylon nanofibrous membranes

“…Generally, when a beverage is filtered through a porous membrane, solid particles accumulates on the filter as a cake, whereas the fluid being filtered with a flow rate inversely proportional to the filter resistance (Foley, 2006;Mahdi & Holdich, 2013). This filter resistance increases with the formation of cells cake on the filter media with different morphologies in the filtration process (Ben Hassan, Lafforgue, Ayadi, & Schmitz, 2014;Mahdi & Holdich, 2013). Membrane filtrations have been used extensively for complete or partial removal of microbes in beer, wine and juice to achieve the highest standards of food quality and safety (Lipnizki, 2010).…”
