Harvesting of microalgae biomass is a major challenge because biomass concentration in the cultures is relatively low (0.5 – 5 g/L) and microalgae cells are very small (5 – 50 µm). As a result, harvesting using off-the-shelf methods such as centrifugation is energy-intensive. This COST action will focus on the development of new cost- and energy-efficient methods for harvesting microalgae. The main criteria for selecting new harvesting procedures are the quality of the product, the biomass concentration for the subsequent process and the associated costs. Research will focus on flocculation-based technologies that require minimal quantities of chemicals (e.g. bioflocculation, autoflocculation, electroflocculation), or membrane-based harvesting processes.
