Abstract: The invention relates to a separation system for simultaneous removal of a solid phase particles and a dispersed phase droplets from a medium being a continuous phase to be purified by filtration, wherein said separation system comprises: a filtration-coalescing element (1) in a form of a fibrous structure, a separating element (2), which is a barrier layer for droplets of said dispersed phase and a drainage gap (3), disposed there between and separating said elements (1) and (2) from each other. Said filtration-coalescing element (1) is a non-woven fibrous structure in the form of a depth non-woven structure composed of fibers packed in a form of a cartridge and it comprises: a filtration layer (1a) being an initial depth filtration layer comprising polymer fibres of nanometric sizes, wherein said fibres composing the layer (1a) have extensively phobic surface properties and having across its thickness a porosity gradient, a coalescing layer (1b) and adjacently following it a dripping layer (1c), both composed of polymer fibres and jointly forming a coalescing structure (1b, c) packaged in the form of a depth gradient structure of fibres, and wherein a porosity gradient across the entire coalescing structure (1b, c) changes in the opposed direction with respect to said porosity gradient in said filtration layer (1a).
