WMO through centrifuge....
I just got my centrifuge up and running and I have had it going for almost 2 days now on the same batch of oil and its STILL pulling tar and crap out of the oil, is this normal? Will the centrifuge always continue to pull stuff out or should I keep it running till it's not pulling anything out? This is something I have little experience with and need some input. Thanks!

How many gallons are you trying to filter?... I would try running small batches of between 10-15 gallons at a time... clean the fuge every hour... what is the size of your fuge... it should tell you how many gallons per hour it can filter

Trying lower gallons of rule first and then going for the higher version can be for sure of the methods that can help you extrapolate the minor results. I think that this is not normal but there are also other factors to consider always. repo trucks for sale

My first batch through the centrifuge took forever as well. I screened it down to 100 micron before running it but I've learned a couple of things since then....
1. Heat Settling
2. Put a junk drain in the lowest point (bottom) of the tank
3. The supply (good oil) valve should be 2 inches up from the valve that supplies the centrifuge pump (which is 2 inches up from the bottom of the tank.
Since doing taking these few things into consideration a full batch normally only takes about 6 hours (50 or so gallons) to run. I get the oil up to about 180 degrees (insulated barrel) then turn the heat off and let it sit for 12 hours (next morning). The heat makes most impurities settle to the bottom. The next morning I will drain off the bottom inch or two from the drum and turn the centrifuge on and let it run for about 5 hours. Note the oil temp after 12 hours is usually right at 150*. At the end of the 5th hour I'll clean the centrifuge and let it run for an additional hour and check the centrifuge again for dirt. Normally there isn't any additional filth accumulated and I'll drain it into a storage container for use in the truck or to a biodiesel making friend to make B100 with.
I'm playing with the idea of building a cold upflow system to use during the summer months because it's free and I like to rude the bike, plus after letting WVO sit for a couple months the good oil on top is normally very dry and clean and requires very little time in the centrifuge.
Note: I wrote that based on WVO not WMO, but the process is the same for both. I use both with no issue following the same process.
