Abstract:
A device for treating a liquid medium, comprising:a reservoir for holding the liquid medium to be treated, the reservoir being in fluid communication with a compartment providing liquid flow through the compartment during use of the device; an ultrasound emitter located relative to the compartment to emit ultrasound into the liquid in the compartment during use of the device, the ultrasound emitter emitting high-frequency ultrasound between about 200 kHz and 10 MHz, wherein the ultrasound emitter is oriented obliquely to the axis of the compartment such that the ultrasound emitted does not generate a standing wave phenomena in the liquid flowing through the compartment; and a microbubble emitter emitting bubbles with an average diameter of less than 1 mm, the microbubble emitter being arranged relative to the compartment so as to emit microbubbles into the high-frequency ultrasound field emitted into the compartment during use of the device.
