Finally got around to getting some pictures uploaded. I was curious how small of a scale i could do and found the gallon jugs worked pretty well. Only cost i was out of was the add a drain plug that i attached to the lid of the blue oil jug, hose, and the black oil can that holds 2.5 gallons. Figured i better get something different from my current jugs so i dont mix up the clean and dirty. I had the power go out and discovered the hard way what the hose that is
now going to the oil pan was for, its meant to prevent the unfiltered oil from getting into the clean when not running. It also came with the tools needed to disassemble as well as extra o-rings. The feed cone and capacity are the main reasons i chose this centrifuge. The clean oil exits the 3 holes near the center of the lid of the bowl. Ill be scaling this up to using 55 gallon barrels and filling them from my settling totes.
Ive also been lucky lately had a person posting free wmo on craigslist and it was 20 x 1 gallon jugs. The gentleman even gave me partial jugs of clean oil just to get it out of his garage. So far its been water and coolant free.
I added an oil extractor (

When i get water contamination ill pour it into gallon or 2.5 gallon jugs. ill leave them sit in the sun then see where the water is on the side view of the jug then use the extractor to pull oil within 3/4 of an inch so im not having a bunch of waste.
I came across my first quantity of white emulsified oil i drained from a push mower that was given to me. Ive been tinkering with the emulsified oil to see if i can get the stuff to separate. Not doing an exact science but i added a bit of rug let it sit in the sun and had a few veins of separation show up after half a week. It didnt progress much after that so i added a touch more rug (at this point the rug seemed to have evaporated from my last trial) with some sea foam fuel treatment (as soon as the sea foam hit it i seen a reaction almost like it was boiling)then again let it sit in the sun after i stirred it. The next day when i went to inspect it i had black oil on top and a bit of water sludge gray stuff near the bottom. Due to such a small quantity im hesitant to say if this actually worked well. Anyone with larger quantities find a method to recover emulsified oil or be willing to tinker with this to see if its workable?
