Here's what i do...
I've got two 55 gallon barrels sitting on drum stands. I fill those up, move them to the horizontal position. The 3/4 bung is off of the bottom by quite a bit. I let them sit this way for a long time -- at least several weeks, but most of the time a month or more. After that, I pull the settled WVO from the barrel and run through a 5 micron filter on the way to my 275 tote tank. In the tote tank, I suspended a huge 1 micron sock filter that holds itself in the 6 inch opening of the tote. I let it gravity filter through this.
I pump from the tote, and there's another 5 micron filter on the way to the truck.
I'm looking for a band heater, I think that if you heated the WVO up at the beginning of settling and allowed to cool slowly, I think you'd get better, faster settling.
So far, most of what I've done has had the help of solar power for heating, it's been warm and the barrels are dark so they get pretty warm...
