Membrane filtration has been considered as an promising harvesting technology in the fields of microalgal biorefinery to produce biofuels and valuable chemicals from microalgal biomass. For developing the effective membrane-based harvesting process to produce highly concentrated biomass, membrane fouling should be controlled because it leads to not only reduced filtration rate but also insufficient reachable concentration of harvested biomass for downstream process. For that, a dynamic filtration using a rotating disk was evaluated in this study, efficiently generating high shear flow near the membrane surface by an independently moving part. It was demonstrated to achieve feasible filtration performance even under high biomass concentration with complete biomass recovery and moderate energy consumption observed.
