 Oil Skimmer
I had a 5 gallon bucket of oil mixed with water. This was largely the oil that was drained from the centrifuge over time. It is about half water. Very nasty stuff. I used the oil skimmer to extract the oil off the top. It worked well.
This photo shows the skimmer picking up the oil. This is the temporary setup. This is the oil coming out of the skimmer and into the heater.

Another shot. The skimmer is just resting on the top of the bucket. This is the complete setup showing the heater and the centrifuge.

This is the results from 2.5 gallons of oil that was floating on 2 gallons of water. I frequently use the oil skimmer to separate the heavy oil and water mix that is often found if the bottom of drums of use oil. Here you can see that the 5 gallons of water and oil mix yielded about 2.5 gallons of oil that can then be centrifuged. It's easier to strip the oil off the top rather than run the whole mess. This is the photo after separation. Bucket on the left is oil and the bucket on the right is water. The skimmer can remove the oil more efficiently than trying to drain it off.
