What's the best way to separate water from oil ??



I know letting it sit naturally separates the two and draining the water off the bottom is easy, but could the process be sped up through polarization seeing as Oil for the most part is non-polar and water is ?



Yes, this topic does have to do with the drying of biodiesel, I posted it here here because there might be more folks looking at this here than in the alternative fuels section.

Some of the oil reclaimers heat the oil and run it through a vacuum chamber to remove moisture faster. bg
 
Heating the oil yet again and running it through vacume chambers can be expensive.



Bubble drying seems slow, and if a 2nd or 3rd wash is necessary the process gets dragged out for many hours.







I did post the ? on biodieselnow.com but have no reply.



Maybe it's a stupid ? and the answer is obvious. Just seems like the water along with the rest of the impurities in it could be recaptured easier with the use of a charge or electrolisis somehow. Maybe I need to go back and study my old chem. books, been 20 yrs. and I can't count out ignorance at this point.

That will work if you can find one. Or you can use a centrifugal filter where it is pumped through under high pressure and the solids are "slung" out. On a ship, they have a high pressure filter system they pump the fuel through to take out the water. The filter element is a stainless system so they don't have to be replaced (for heavy fuel). Then they have an oily water separator that is very efficient. They pump the bilge water through it and the water is separated and pumped over the side. The oil is then reclaimed. Why not just use one of the RACOR oil/water separator filters?

The Amsoil By-pass elements will remove water from oil!
