Why Look For An Algal Closed PBR
Sustainable energy business people are now searching for the best bioreactors with the right stuff. What is the right stuff you ask? Well it must be a algae farm that meets numerous challenges: be affordable, scalable, able to manage changing climates at various customer locations.
Low Cost to Execute

Constant Harvesting
Harvesting the algae will be a issue depending on the system. It will take more effort to harvest algal biomass from an open pond process than it will from a continuous harvesting algae PBR. Constant harvesters do just that, constantly harvest algae cake, you now will only need staff to move the algal cake to the next stations for drying out and oil extraction.
Oil Extraction
* There are 3 well-known methods to remove the oil from oilseeds, and these techniques apply equally well for algal biomass too:
1. Expeller/Press
2. Hexane chemical oil removal
3. Supercritical Fluid extraction
* Expeller/Press
* Expression/Expeller press-When algal mass is dried out it keeps its oil content, which then can be “forced” out with an oil press. Many commercial manufacturers of vegetable oil use a combination of mechanical pressing and chemical solvents in extracting oil.
* While better procedures are emerging, an easy process is to use a press to extract a large percentage (70-75%) of the oils out of algae.
* Hexane Solvent Method
* Algal oil can be extracted using chemical substances. Benzene and ether have been used, but a popular chemical for solvent extraction is hexane, which is comparatively cheap.
* Super-critical Fluid Method
* Supercritical removal involves, pressure and heat to burst open algal cell walls.
No matter what algae method you chose just make sure it meets your needs and production goals.
