Abstract. Efficient microalgae dewatering is a major problem that continuously plagues industrial-scale processing of microalgae metabolites for commercial use. Large scale cultivation of algal biomass is typically produced with a high volume of water (<95%). As a result, harvesting concentrated microalgal cultures presents a significant economic challenge to industries such as algae-based fuels that are critically dependent on improvement of techniques and practices designed to remove algae from water. One promising strategy is the Solvent Phase Algal Migration (S.P.A.M.) process, which is a technique designed to maximize migration of algal cells to a solvent fraction while simultaneously displacing water in a separate fraction. This investigation evaluates the S.P.A.M. dewatering performances of various factors in a comparative study.
