The swirl flow membrane emulsification method involved the generation of a centrifugal kind of flow in the continuous phase. This exerted higher radial shear stresses on the membrane wall which overcame the higher kinetic energy of the dispersed phase emerging from membrane pores when high dispersed phase fluxes were applied.

The continuous phase was housed in a suitable vessel in which the membrane was submerged. Figure 2. The cross-flow membrane emulsification system used in this study was setup as To determine the effect of membrane morphology on pore activation, we developed and experimentally validated a model that describes the flow phenomena in and under a membrane with uniform pores First is the membrane pore activation since only a fraction of the membrane pores are active in the emulsification process. This fraction increases when the dispersed phase applied pressure increases from zero at no flow to ~50% or more depending on the surface porosity and system characteristics. First is the membrane pore activation since only a fraction of the membrane pores are active in the emulsification process.

The low throughput of the disperse phase is one of the issues in cross-flow membrane emulsification. This is apparent in the low percentage of pores at which droplets are formed (few active pores).

The membrane used in the study had a very regular matrix of very uniform pores, rather than the usual tortuous pore channel depth filter commonly used for membrane emulsification. However, even with this regular pore geometry the deduced percentage of active pores was only about 37%, when operating with 29 mM surfactant concentration and above.

2014-08-22 A very narrow pore size distribution, low pore tortuosity and controllable membrane porosity make AAO one of the top performers given its permeability/pore diameter ratio .

The primary emulsion was permeated through the uniform pores of a glass membrane into the external water phase by the pressure of nitrogen gas to form the uniform w1/o/w2 double emulsion droplets.

2013-09-30 · Droplet size obtained is calculated and experimented to be usually 2–10 times larger than membrane pore size. Pore size, inter-pores distance and surface hydrophobicity are important factors that greatly affect the emulsification success [8,9]. In a study, a stirred dispersion cell apparatus provided by Micropore Technologies Ltd had been used.

While the addition of the inorganic salts (KCl and CaCl2) provided an increase in the pore size of the top surfaces of all membranes, by means of the contact angle, it was verified that the hybrid membranes presented smaller angles when compared to the PA6, probably, due to the superficial peculiarity of the clay to react with water.

While smaller scale air purification is done by using adsorbing materials such as activated carbon.

Increasing the emulsifier concentration decreases droplet size, as does increasing the shear force applied to the forming droplets, either This model is used to show that in most cases the estimation of a membrane pore size distribution by using the liquid displacement method is not correct. Just as in membrane emulsification, pores become active at higher transmembrane pressures than expected. Finally, in chapter 6 the effects of several membrane parameters on membrane emulsification Membrane emulsification has received increasing attention over the last 10 years, with potential applications in many fields. In the membrane emulsification process, a liquid phase is pressed through the membrane pores to form droplets at the permeate side of a membrane; the droplets are then carried away by a continuous phase flowing along the membrane surface.
