What to Look for in an Algae Bioreactor
by Vic G.
Renewable Energy entrepreneurs are now looking for the best bioreactors
with the right stuff. What is the right stuff you ask? Well it has to be a algae
farm that meets a number of challenges: be affordable, scalable, able to
handle variable temperatures at different client sites.
Low Cost of Implementation
The first area of concern is always the cost. As with all systems of a
commercial scale, cost is king. The technology at this point has many faces
to include row crops, large open pond systems, race way systems and photo-
bioreactors. Thy system you choose must have nutrients to feed the algae,
water and sunlight. Your carbon dioxide inputs can be active or ambient air.
Cross contamination of the algae is a concern, but intended use of the algae
will be your guide.
Harvesting the algae will always be a concern depending on the system. It
will take more effort to harvest algae from an open pond system than it
would from a continuous harvesting photo-bioreactors. Continuous
harvesters do just that, always harvest algae cake, at this point you will only
need staff to move the algae cake to the next stations for drying and oil
