Difference between revisions of "Ultrasonication"

The requirements on the origin and composition of the feedstock may vary since the ultrasonication can be utilised at various points in the value chain of biowaste valorisation.

During the ultrasonication treatment ultrasound is transmitted through any physical medium by waves that compress and stretch the molecular spacing of the medium through which it passes<ref name=":0">{{Cite book|author=Hugo Miguel Santos, Carlos Lodeiro, and José-Luis Capelo-Martínez|year=2008|section_title=The Power of Ultrasound|editor=José-Luis Capelo-Martínez|book_title=Ultrasound in Chemistry: Analytical Applications|publisher=Wiley‐VCH Verlag GmbH & Co.

When the negative pressure is large enough, the distance between the molecules of the liquid exceeds the minimum molecular distance required to hold the liquid intact, and then the liquid breaks down and voids (cavitation bubbles) are created<ref name=":0" />. <!-- Maybe it is easier to understand when you add figures to the text.
