The main goal of this paper was to investigate the redistribution of solid deposits during filtration of droplets in polypropylene melt-blown fibrous filters. The understanding of deposition, as well as re-suspension of the mixed particles requires knowledge about the basic physical and chemical processes occurring on the fiber surface and the interactions between particles. During this work the following phenomena were analyzed: deposition of only solid particles and only droplets on fibers, interactions between free droplets (coalescence) and solid particles (agglomeration), evolution of solid particle deposits and impact of the presence of liquid on this evolution. The scanning electron microscope was used to observe mentioned phenomena at various stages of the process. As a challenge aerosols solid silica particles (Arizona Fine Test Dust) and oil droplets (DEHS – di-ethylhexyl- sebacate) suspended in the air were applied.
