A variety of microalgal cell harvesting methods have been evaluated including centrifugation, electrocoagulation, filtration and ultrafiltration, flocculation, flotation, and sedimentation. Provide a detailed description for each of these algae cell harvesting methods, and indicate how well these methods work to concentrate the microalgae according to published literature. Based on published accounts of efficiency of the algae harvesting methods and the energy requirements/cost associated with each method, indicate the advantages and disadvantages of each method for use in an industrial scale algal biofuel production system.
