Abstract
Different ways of dispersion of solid-phase particles are considered: pulse, electrostatic, and pneumatic. The model experiment on sedimentation of fine airborne particles of polymeric substance kollidon is made. A change in the concentration of the studied aerosol particles at ultrasonic sedimentation is analysed. The pilot study has shown that electrostatic generation of aerosol considerably increases the speed of sedimentation of particles with application of ultrasound.
