Street Sweeping to Reduce Organic Pollutants Sorbed to

as the dispersed phase. Interestingly, the results have shown that the morphology can be controlled not only by adjusting experimental parameters specific to the membrane emulsification step such as membrane pore size and pressure, but also by changing the nature of organic solvent. Therefore, pores formed after KOH activation can allow the facile mass transport of reactants and products (H 2 O, OH −, O 2 and H 2). Additionally, the pores mitigate diffusion limitations and are favorable for easy formation of the interfacial area between active sites and reactants, eventually increasing the overall electrolyzer Nanoparticles via Cross-Flow Membrane Emulsification Jae Man Shin1†, Minsoo P.

Kim*,1 1 Department of Chemical and Biomolecular Engineering, Korea Advanced Institute of Science and Technology (KAIST), Daejeon, 305-701 Republic of Korea However, for the 3 μm pore size membranes, at a similar cross-membrane pressure and for a similar formulation, we can expect that a larger fraction of the pores are active. Obviously, if more pores are active, then the mean distance between two growing drops on the membrane surface at any given time will be reduced and the possibility of neighbouring drops interacting will be increased.

This is apparent in the low percentage of pores at which droplets are formed (few active pores). 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 (microsieve).

Short CV

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.

As a 3.1 Characterization of tubular ceramic membranes - pore diameter and morphology The morphology of tubular ceramic membranes, evaluated by SEM, can be seen in Figure 2 . It is observed that the membrane structure is characterized by irregularly distributed pores with a relatively complex shape.
