Abstract
A device for treating liquid medium has an ultrasound emitter located relative to a compartment of a container holding a liquid medium and a microbubble emitter located relative to the compartment. The ultrasound emitter emits high-frequency ultrasound between about 200 KHz and 10 MHz. The microbubble emitter emits bubbles with an average diameter of less than 1 mm.
Claims23
A method of treating a liquid medium to neutralize, remove and/or prevent the growth of undifferentiated cells and/or of microorganisms present in the liquid medium, wherein the liquid medium contains salts, the method comprising injecting gas comprising microbubbles and high frequency ultrasound into the liquid medium, said high frequency ultrasound being between about 200 kHz and 10 Mhz, wherein exposure to the gas and high frequency ultrasound inhibits a recovery threshold of the undifferentiated cells and/or microorganisms, and electromagnetically treating the medium so as to modify at least one of the nucleation, formation and growth of salt crystals in the medium.
A device for treating a liquid medium, said device comprising:
- a compartment for holding said liquid medium;
- an ultrasound emitter configured and located with respect to the compartment to expose the liquid medium to high frequency ultrasound, said high frequency ultrasound being between about 200 kHz and 10 Mhz;
- a gas emitter configured and located with respect to said compartment and ultrasound emitter to emit gas comprising microbubbles into said compartment and into an ultrasound field produced by the ultrasound emitter;
- wherein said compartment, said ultrasound emitter, and said gas emitter are configured to inhibit a recovery threshold of undifferentiated cells and/or microorganisms present in a liquid medium placed in said compartment.
