I don't know if you can do this effectively with a filter, nor how it could be done at time of pickup. Water content might settle out eventually, or it might not. Once you've got it back home, try raising the temp to 130-140 deg F (55-60 deg C). keep it there for 15 minutes or so, then let it settle overnight. This will settle out the water, so don't use the bit at the bottom. Some people say this method doesn't work well, but it always works well with me, and others. Give it a try, if you're not satisfied then go to higher temps and try boiling the water off. Boiling takes more energy, but without the need for overnight settling you could use the heat for processing, catching the oil "on way down" at 130-135 deg F, the usual processing temp. Check first whether the oil needs dewatering or not. Heat some up in a small pot on the stove; if it starts crackling at about 130 deg F, or maybe less, there's water in it, remove it. If no crackling by 160 deg F or so, no need to dewater it. regards Keith ------------------------ Yahoo! Groups Sponsor --------------------~--> Make a clean sweep of pop-up ads. Yahoo!
