How is biomass harvested from algal cultures?

Biomass from algal cultures is typically harvested through various methods depending on the type and size of the algae. One common technique is centrifugation, where the algae culture is spun at high speeds, causing the heavier biomass to settle at the bottom. Filtration can also be employed, where the culture is passed through a filter that retains the algae biomass while allowing the liquid to pass through. Flocculation is another method in which chemicals are added to the culture to encourage the algae to clump together, making it easier to separate from the liquid. Once harvested, the biomass can be further processed for different applications such as biofuels, food supplements, or wastewater treatment.
