The present invention relates to fluid cavitation processing method, and more particularly, to the cavitation treatment of fluids specific content of water or other liquid layer is more than 30-35% of the total weight. Disposed within the individual cells, a plurality of fluid media, it is possible to subject the simultaneous processing. A simultaneous ultrasound guidance cavitation treatment method of a plurality of cells filled with a fluid medium, a method which requires placing the cells in a bath filled with the treatment fluid, the material of the fluid cell represents the same or this specific acoustic resistance close to the acoustic resistance of the processing fluid, sufficient to generate in all the cells that are exposed sufficiently grown acoustic cavitation in a particular treatment fluid to the treatment fluid and treatment acoustic wave amplitude are generated such, the process fluid reservoir has a rectangular shape, in this rectangular tank, the acoustic standing wave, generated in the processing fluid, an elastic membrane having the self-resonant first harmonic frequency characterized in that it is reflected from the designed tank wall and bottom tank wall which faces the rectangular tank, the first harmonic frequency may be the same or different, the length of the vessel "a" and width "b ", as in the following equation, by the lateral wall of the vessel at the treatment fluid is selected as a multiple of a quarter of the wavelength to be excited, a = (k / 4) * (c / f i), b = (k / 4) * (c / f i), However, "c" is the acoustic velocity which is evaluated in the processing fluid (m / sec),"F i" is the first harmonic frequency of the lateral wall of the tank (Hz), "K = 1,2,3 ..." is an integer, Height "h" of the treatment fluid level is designated as one of a multiple quarter of the wavelength to be excited by the bottom of the vessel, oscillating frequency "f i" is evaluated by orthogonal multi-factor "k", a method It is. The method is intended to ef
