Default Building a waste motor oil filter setup!

Just spit balling here but, how much flow gph/psi? can a spin on type oil filter handle? I'd like to do a final filter of 55 gallons of used motor oil through a 2-5 micron filter.

I have a 275 gallon tote on the side of my shop for gear, motor and trans oil almost full. I would like a build a low cost wmo burner of some type just to play around with, simple gravity drip wouldn't need much filtering but if it goes through a pump more would be necessary.

I like the centrifugal filters for this, at least in theory. Have not tried it, but the appeal to me is that they can be cleaned as necessary without having to buy new cartridges. Should filter adequately to allow the oil to be added to diesel fuel and used in a diesel engine.

X2 on using a centrifuge and the slower you flow the oil the more solids are removed. Not many cheap centrifuges for sale.

Good video from YT;

K.I.S.S.
Do a gravity feed burner, requires minimal filtration and no power to run it. This design is claimed to work well, if you don't have some big brake drums laying around an old compressor tank works too.
http://www.tractorbynet.com/forums/b...waste-oil.html

I have a mil-surplus portable heater designed to run on JP5 IIRC, it works great using a 50/50 blend of diesel/wmo, as long as temps are above freezing. Below freezing the mixture gets too thick, it does not atomize fuel right, and safety feature shuts pump off because amperage load is too high.

Years ago about early '80's Mother Earth News (before they went political) had a piece on this. Used a system that dripped oil on a disc in an ordinary wood/coal stove. Needed to have a small wood/coal fire under it. Heated oil supply with waste heat from stack and filtered by gravity through rolls of toilet paper. Old issues are available for your computor and one of the little deals that go in the UBC port.

Tom over on machine builders network http://kramerville.net/mbn/ built a nice little centrifuge type cleaner about a year ago. Might be of interest to scope out.

For some reason Matt has it set up that you have to be logged in to see some of the pictures. Depends on where they post them. Tom is one who you need to be logged in to see. But a membership is free to all comers. (Site supported by a bunch of us regulars making contributions.)
Anyway, short answer just get an account and log in. All of Tom's pics will show up.

Hard to say, too many variables. 80-90 wont flow nearly as fast as 0w-20, temperature makes a HUGE difference in how much can be sent through a filter. Also the safety by-pass is built into the base, not the filter it self and varys with the application. Full flow engine oil filters typically operate at the same pressures you read on a gauge so figure they are good for 50PSI or so but the burst pressures are much much higher than that. Pick you filter media and ask the manufacturer for data? I gravity feed my pre filter from 275 totes sitting outside the shop on a stand. It takes a longtime but takes care of itself. All I have to do is remember to shut the valve off when I leave when the tank is near full.

As for drip fed heaters. For 20 years I screwed around with every drip fed design known to man looking for a reliable and SAFE way to burn waste oil in my shop and I will state here that it doesnt exist plus I didnt get anything done in the shop except fiddle with them. I finally figured out if I am not going to get anything done in the shop I might as well stay in the house with ma, LOL.

I bought a Lanair waste oil heater and now the shop stays warm, it is safe and I dont have to screw with it except clean the ashes or change the thermostat settings.
