In the paper, the aerodynamics (pressure drop) of the existing packing for biofilters is considered. Experiments on practical suitability of a packing from a natural origin for the biofilter – pine cones are made. Results of the research of the aerodynamic resistance of packing from artificial materials (foam rubber cubes, silicagel) and natural materials (lump wood, cone, and bark) are given. These packing are widely used in the heat- mass transfer devices. The experiments were carried out on the experimental column. The diameter of the column is 200 mm. The height of the column is 1000 mm. The results of the experiments are generalized using similarity criteria – Reynolds. The geometrical characteristics of this random packing (pine cone) are received and compared with other packing from artificial (Raschig ring, Pall ring, Berl saddle, Flexirings) and natural (wood chips, bark) materials. The aerodynamic tests of a packing are carried out and compared with the data of other packing. Some recommendations about improvement of the performance data of the packing are made.
