     in this study, the focus is on magnetic separation of fresh water algae chlamydomonas reinhardtii and chlorella vulgaris as well as marine algae phaeodactylum tricornutumand nannochloropsis salina by means of silica-coated magnetic particles. due to their small size and low biomass concentrations, harvesting algae by conventional methods is often inefficient and cost-consuming. magnetic separation is a powerful tool to capture algae by adsorption to submicron-sized magnetic particles. hereby, separation efficiency depends on parameters such as particle concentration, ph and medium composition. separation efficiencies of >95% were obtained for all algae while maximum particle loads of 30 and 77 g/g were measured for c. reinhardtii and p. tricornutum at ph 8 and 12, respectively. this study highlights the potential of silica-coated magnetic particles for the removal of fresh water and marine algae by high gradient magnetic filtration and provides critical discussion on future improvements.
