Abstract:

Microalgae harvesting methods are generally not efficient and cost-effective due to the inherent characteristics of microalgae. These problems can be addressed by membrane technology for effective microalgae harvesting and nutrient removal. This chapter focuses on the performance of membrane-based systems, membrane fouling, and fouling control approaches during the microalgae harvesting process. Operational parameters (i.e., hydraulic retention time, light conditions, etc.) should be optimized to obtain better performance. Alginate-immobilized microalgae beads and solid carriers accelerate microalgae growth and mitigate membrane fouling by the adsorption and degradation of foulants. A membrane bioreactor combined with microalgae photobioreactor effectively treats various types of wastewaters and enhances microalgae cultivation. Membrane modification and in situ physical cleaning methods (i.e., patterned membrane, turbulent jet-assisted microfiltration, etc.) remove foulants from the membrane surface and improve membrane permeability, thereby reducing the specific energy demand and harvesting cost. Development of novel carriers and techno-economic analyses of different membrane-based systems is needed in future studies.
