Why liquid displacement methods are sometimes wrong in estimating the pore‐size distribution

Abstract

The liquid displacement method is a commonly used method to determine the pore size distribution of micro-and ultrafiltration

The impact of mass transfer and interfacial expansion rate on droplet size in membrane emulsification processes

“…The characteristic parameter used to discuss the effect of the flowing continuous phase is the wall shear stress. Previous studies have shown that the droplet size decreases as the wall shear stress increases [5,7,19]. One popular explanation of this phenomenon is that the flowing continuous phase creates the drag force that pulls the droplets away from the pore mouths after reaching a certain size [15].…”

“…For extensive and recent reviews on membrane emulsification consult Joscelyne and Trägårdh [4], Charcosset et al [5] and Gijsbertsen-Abrahamse et al [7]. Other authors have described droplet formation depending by considering the type of mechanisms causing the droplets to detach and or the systems sensitivity to operating conditions [8][9][10].…”

Recent developments in manufacturing emulsions and particulate products using membranes

“…For example, for droplets between 10-100 µm microchannel (MC) emulsification process has, in particular, been considered an effective method of producing uniform particles, with typical coefficients of variation of 5% (this compares with normal CVs of about 10% for other membranes). The current state of membrane emulsification technology and the underlying process phenomena have been reviewed by several authors [93][94][95][96]. These articles are mainly focused on the influence of process parameters and membrane properties on the droplet size distribution and the transmembrane flux.…”

Universal Dripping and Jetting in a Transverse Shear Flow

“…Here we study droplet formation in a cross-flow membrane emulsification (XME) geometry, a high-throughput method for generating monodisperse droplets [8][9][10]. In XME, the dispersed phase (DP) is forced through an orifice in a planar membrane into a simple shear flow set up by a second continuous phase (CP) flowing parallel to the membrane surface; see Fig.…”
