  The research on the physical features of transportation and structurization
processes by the air-dust aerosol in the granular filtering medium with the
cylindrical coal adsorbent granules in an air filter of the adsorption type in
the heating ventilation and cooling (HVAC) system at the nuclear power plant is
completed. The physical origins of the coal dust masses distribution along the
absorber with the granular filtering medium with the cylindrical coal granules
during the air-dust aerosol intake process in the near the surface layer of
absorber are researched. The quantitative technical characteristics of air
filtering elements, which have to be considered during the optimization of air
filters designs for the application in the ventilation systems at the nuclear
power plants, are obtained.
