Ultrasonication is a physical treatment to disrupt, disperse, and/or homogenise biomass via the application of ultrasonic frequencies (>20 kHz).
Feedstock
Origin and composition
Process and technologies
Product
Ultrasonication can be used to produce:
- Biofuels
- Emulsions (such as nanoparticles, nanoemulsions, nanocrystals, liposomes, wax emulsions)
- Extracts from biomass (such as polysaccharides[1], oil, anthocyanins and antioxidants[2])
- Purified wastewater
Furthermore, ultrasonication is also utilised in following processes:
- Adhesive thinning
- Cells disruption
- Degassing liquids
- Polymer and epoxy processing
- Ultrasound assisted oxidative desulfurisation of crude oil[3]
