rotating wheel 2 systematically position themselves against the corresponding outlet apertures 8 of the rotating wheel 2 thereby stimulating periodic perturbation of the stream and corresponding mechanical vibrations in the liquid the liquid proceeding through the outlet apertures 11 of the annular chamber 4 arrives in the cavity 12 of the stator 7 from whence the processed liquid is expelled through the outlet aperture 13 the number of outlet apertures 11 of the annular chamber 4 is selected from a range of from one to k however it must be borne in mind in this case that all other conditions remaining the same an increase in the number of outlet apertures 11 while it adequately increases the volumetric output of the process also lowers the effectiveness of the conditioning of the liquid in terms of a solution of the problem offered by the invention in accord with the basic working embodiment fig1 of the device for bringing about the described method of conditioning a liquid it contains a rotor 14 which includes a shaft 15 located in the bearings 16 and 17 and equipped with a gasket 18 the rotor 14 contains at least one rotating wheel 2 connected with the shaft 15 and made in the form of a disk 19 with a peripheral annular wall 20 which annular wall has a cylindrical external surface 5 in this wall 20 are located a series of outlet apertures 8 for the liquid uniformly distributed along the periphery the.
