FIELD: separation, concentration and purification of liquid and gaseous media. SUBSTANCE: proposed filter element is made in form of cylinder with channels on its external surface. Surfaces of channels are coated with thin porous membrane layer. Channels with membrane layer are molded in form of helical slot-like line. Filter element is inserted in bounding ferrule. Inner hole is used for removal of flow passing through membrane. EFFECT: reduction of labor consumption in manufacture of filter element; increased specific surface of separation; increased productivity; simplified regeneration of filter element; enhanced efficiency. 2 cl, 2 dwg, 1 tbl |
