Abstract
Conditioning and concentration of microalgae are accomplished by the process steps of grinding a dilute aqueous dispersion of microalgae in the presence of grinding media and then applying adsorptive bubble separation. This process is amenable to the use of dilute feed microalgal dispersions such as are encountered in the production of algal biomass for biofuel applications.
