  The processes of structurization of dust precipitations in granulated
filtering mediums, formed by the monolithic glass spherical granules with the
diameters of 2mm and 3mm, are re-searched. The distinctions between the
distributions of filtered coal dust masses in the air filters with cylindrical
granules and the air filters with spherical granules, are found. The influences
by the filtered dust masses on the air resistance of both the air filters with
the cylindrical granules and the air filters with the spherical granules are
described. The conclusions on a possibility of the use of various chemical
adsorbents with different geometric forms and volumetric dimensions to improve
the filtering properties of granulated filtering mediums in air filters at
nuclear power plants are formulated.
