The Ultrasonic Foam Breaker is an electro-acoustic device capable of generating ultrasonic waves of high intensity which efficiently break foam bubbles without contaminating the treated solution.
Hence, the ultrasonic system is not in direct contact with the fluid phase whilst in operation. The mechanism of an Ultrasonic Foam Breaker is a combination of the following effects: high acoustic pressure, radiation pressure, resonance of bubbles, acoustic streaming.
Other factors, such as the atomization of the bubble surface, may also contribute to foam rupture.
The ultrasonic generator produces highly focused radiation that levels of acoustic pressure higher than 170 dB may be achieved at a focal area.
