Abstract: Harvesting of microalgae biomass using cost efficient method is a major challenge for obtaining value added products at larger scale. Although the use of centrifugation, filtration, and electrocoagulaton methods are feasible for high harvesting efficiencies, their energy requirements and cost remained worrisome for biomass harvesting. This review presents the flocculation methods involving pH induced, chemical flocculants and bioflocculants as promising approach for large-scale and low-cost harvesting of microalgal biomass. When using different flocculants for microalgae harvesting, it is necessary to consider flocculant type, dosage, cost and type of microalgae for efficient flocculation. Therefore, the selection of flocculation method should therefore be assessed based on multiple parameters on the level of each microalgae species.
