Abstract: The present invention relates to a method of simultaneous cavitation treatment of liquid media having different compositions. The acoustic cavitation may operate by a double resonance effect inside a flow mechanical oscillatory system—formed as a rectangular channel of finite length. At opposing sides of which, the channel side walls generate in-phase sound oscillations. The interior of the mechanical oscillatory system rectangular channel further has additional flow channels therein to supply treated liquid media, the specific acoustic resistance of material of additional flow channels is close to the acoustic resistance of operating liquid. The width of the channel interior h is a multiple of a quarter of wavelength for the operating liquid at the frequency equal to the basic frequency of system-channel. The amplitude of system-channel wall oscillations creates a fully-developed acoustic cavitation mode over the entire inner volume of operating liquid including the flow channels liquid media therein.

Abstract: A method and system for ultrasonically and simultaneously induced cavitation processing of fluid media-filled cells is provided. The method and system requires placing of cells in a bath filled with process fluid, wherein the fluid cell material exhibits specific acoustic resistance to be equal or close to that of the process fluid, sufficient acoustic wave amplitude is produced for specific process fluid so that well-developed acoustic cavitation occurs in process fluid and within every cell exposed to processing. The process fluid bath structure has a rectangular form where an acoustic standing wave is produced in the process fluid and is reflected from the bath walls and bottom. These walls and bottom may be designed as elastic membranes to have a self-resonant first harmonic frequency.

Abstract: The subject invention refers to the field of cavitation treatment of liquid medium as well as the medium having the density of water or other liquid phase exceeds 65-70% of total mass. Method of ultrasonic cavitation treatment of liquid medium is what the mode of acoustic cavitation is being simultaneously generated on two or several different frequencies, at that the mechanical vibration system—channel with rectangular cross-section, is made in the form of tandem membranes having different frequencies of fundamental harmonic of vibrations, generating of acoustic vibrations with formation of standing wave is performed in phase over against the channel, that in turn generate quasi-plane standing waves, corresponding with vibrations frequencies of the membranes, in the channel clearance.
