This study investigated the magnetic harvesting of algae via magnetic nanoparticles (MNPs). MNPs achieved high harvesting efficiency, over 95.0%, for various algal strains and could be effectively reactivated for low-cost algae separation. Comparing different harvesting efficiency, synthesis cost and reactivation methods, the present work evaluated the cost-effectiveness of different MNPs types and discussed the key factors affecting harvesting cost. Our results indicated a significant low cost

Given the fact that algae harvesting is one of the most cost-consumption step in bioenergy production, we suggested magnetic algae harvesting with naked and reactivated MNPs as the most cost-effective technique for future industrial application.
