Innovative Ultrasonics specializes in process development, engineering design, installation and equipment in the area of high-powered ultrasonics for new and existing industrial applications.


High powered ultrasound can be used to induce the rapid and controlled removal of gases from liquid systems, due to the cavitational effects of ultrasound. Any dissolved gases or bubbles in the matrix act as nuclei for the formation of cavitation bubbles. Such bubbles are not easily collapsed in the compression cycles and continue to grow during the rarefaction cycles, filling with more gas. As they increase in size they float to the surface of the liquid. As rarefaction and compression cycles occur very quickly when ultrasonics are applied, the de-gassing process appears to occur instantaneously.

Ultrasonic de-gassing is used commercially to remove the volatile gases from brine under pressure. This contrasts with conventional methodology where the brine is de-pressurised and the volatiles boiled off, a much slower and more energy intensive process. Ultrasonic de-gassing can be applied to highly viscous systems, such as molten glass and metal where it is used commercially, and could also be used to remove air from chocolate or other viscous foods where gas removal may otherwise be very difficult.
