I'm getting ready to start building a test system. First I'll filter down to 75 microns to get the large particles out of the oil. This is a cold filter to also remove some of the solids as well.

This is dumped into a 35 gallon water heater. Water heater is sealed and turned out to cook out the water. I'm hoping that the pressure relief valve will let the steam out from the water.

After allowing the heated oil to cool sufficiently I'll then open the drain on the water heater to let any standing water and gunk out of the bottom. It will then be filtered down to 5 microns into a 55 gallon drum and allowed to settle for as long as I can manage to let it sit. It will then be siphoned into another 55 gallon drum for storage.

I could possibly rig the water heater to pull a vacuum assuming I don't do something boneheaded like overfill the tank I should be able to just draw it out one of the water heater supply lines.
