This is the feed stock. About 2 gallons of green algae. I'm not sure what strain it is but it's one that occurs naturally here in the Northwest.
|
This gives you an idea of the concentration.
|
After adding the little initial sample you can immediately see the algae being captured.

I added the algae water as fast as it would go down the funnel.
|
This is the outflow.
|
After running about a gallon you can see the results side by side. I'm not sure if I'm recovering 100% but it is recovery a large percentage. I'd need to experiment with the feed rates. Every material separates at a different rate.

Check out the collected algae. Algae in interesting in that it's a single cell. It will pass through even the finest of filters.
|
As the centrifuge slows much of the algae remixes with the water in the bowl.
|
Once the bowl stops you can see the algae cake that has formed. This cake would then be dried and pressed for oil.
