This process—which forces the algal paste into a nozzle that removes oil and expels much drier biomass—can extract up to 70% of the algal oil, but generally requires a dry algae feedstock. Dry algae is the product of dewatering. This process is commonly combined with the hexane solvent method.
Can algae be used as a biofuel?
Processing algae is necessary to convert algae to biofuel. The harvested algae has to undergo several steps in order to produce consumer-grade products, such as biodiesel and bioethanol. In order to extract the oil found in the algae cell walls, known as lipids, a separation process must take place.
How does algae harvesting work?
During the harvesting, algae are separated from their culture substrate and processed further to become a high-quality concentrate. The harvesting technology used has a decisive influence on the efficiency of the overall process: The aim is to keep both the investment costs and the operating costs for energy, water, etc. as low as possible.
What is the new algae harvesting system?
to revolutionize the algae industry. that produces crystal clear permeate and a 15-20% algae concentrate with exceptionally low energy use. This revolutionary new algae harvesting system uses advanced membranes to achieve 100% harvest efficiency and eliminate the need for secondary dewatering.
