METHOD OF ULTRASONIC CAVITATION PROCESSING OF FLUIDS AND OBJECTS PLACED THEREIN Russian patent published in 2012 - IPC B08B3/12 A61L2/25 A23L3/30 B01F3/10 

FIELD: process engineering.

SUBSTANCE: invention relates to treatment of fluids by cavitation. Oscillatory system with fluid and objects consists of walls each being made up of membrane secured on its edges that features intrinsic frequency equal to first harmonic, allowing for oscillator weight. Ultrasound waves are emitted by all membranes at a time to produce superposition of waves with generation of standing acoustic waves or several waves with different frequencies. Amplitude of resonance oscillation of every membrane exceeds the threshold of acoustic cavitation for fluid and objects therein. Membrane frequencies and phase characteristics are selected to mate or to differ to produce cavitation effects with due allowance for medium characteristics. Oscillatory system may have arbitrary shape, flow or stationary mode of fluid motion.

EFFECT: higher efficiency of cavitation effects.
