Implications of cell composition and size on the performance of microalgae ultrasonic harvesting
Substantial economic challenges exist across the value chain for microalgae-based biofuels and bioproducts. Acoustic harvesting could dramatically reduce harvesting costs and directly address current energy barriers to separating algae from growth media. This technology utilizes ultrasonic standing waves to create an acoustic radiation force that, due to differences in the acoustic properties of the cells and media, causes the microalgae cells to agglomerate and settle out of the solution. The magnitude of the acoustic radiation force is directly related to the cell radius and acoustic contrast ...
