I think if you want to have enough you have to arrange for too much. WVO isn't the only thing we have too much of. It's a bit like growing food, the problem is surplus. Do you make more biodiesel than you require as well, and if so what do you do with it? >Cubies of WVO were filling >up my shed. Ah, another question - what exactly is a cubie? I don't think I've ever seen one. Sometimes we pump the WVO out of drums into 18-litre carboys but mostly we get it in the 18-litre metal cans it comes in. >I got a few 55 gal drums to store the oil in and found that after settling >in the cubies for a few weeks, the oil was very clear.

We do something similar, no filtering, gravity and settling work just fine. I think if people don't have the time to wait for it to settle it would be worth increasing the WVO supply and reserves to make the time. We need a couple more settling drums, I've got the drums, I'm about to weld together the stands. I don't pump it out of the top though, I use a bottom drain and a standpipe, drain the stuff at the bottom every now and then and resettle it the same way. I don't bother much with dewatering/drying, it's seldom necessary. What's the average titration level of your WVO, Tom? Do you filter your biodiesel before use? Thanks again.
