An alternative to conventional membranes are dynamic membranes consisting of an unconsolidated porous medium. Dynamic membranes have the advantage of enabling easy cleaning of the inside of the pores. Experimental research carried out to date has focused on the application of hydrophilic dynamic membranes composed of glass microbeads for producing o/w emulsions. The aims of this study were to determine the efficiency of droplet size reduction in a w/o emulsion when passed through a dynamic hydrophobic membrane consisting of a bed of irregular polymer particles, and to assess the effect of multiple membrane passes on the properties of the w/o emulsion. The dynamic membranes evaluated in the tests were found to reduce the diameters of premix droplets when an appropriate pressure level was reached. Higher bed porosity was associated with greater fluxes achieved across the packed bed, but the resulting emulsions were less homogeneous. Multiple passes of the emulsion through the dynamic polypropylene membrane led to a further reduction in droplet size, but it was accompanied by a decline in emulsion homogeneity.}, type={Article}, title={Effects of multiple passes through a dynamic membrane on the properties of w/o emulsions}, URL={http://www.czasopisma.pan.pl/Content/125942/PDF-MASTER/art02_int.pdf}, doi={10.24425/cpe.2022.142285}, keywords={DMTS system, dynamic membrane, water-in-oil, premix membrane emulsification, membrane homogenization}, }
