gravity filtration
 

.

hi guys,

anyone has some info or experience with gravity only filtering wvo
is the gravity itself enough or it must be pushed by pump,presuming that is
outside temp 25C / 75F and filter setup is 20/10/5 micron (in filter housing)?

thanks

Everything you need to know here: Ron Schroeder upflow filtering method. - Forums

It works and slowly produces as high a quality of oil as my bowl centrifuge.

Lots of experience with gravity filtration. Works fine as long as you have plenty of time. Heat will speed the flow.

Immediately after my de water cycle I drain threw the filter. I set the bottom drain to trickle as not to overwhelm the filter outflow. I've even been brave enuf to walk away for a few hours.

That's it! simple and adiquate for my personal use. very easy and certainly a lot cheeper than pumps and filter housings.

WVO station
 

Here is my WVO fuel station.
Settled, dewatered oil goes in the top 5 gallon bucket which has a
plastic 100 micron strainer that fits over the top lip.
(Strainer shown in front of top bucket)

That drains into larger blue bucket which has 25 micron sock filters in it.
(Sample sock filter shown in front)

Finally, the fuel is drained through a 5 micron sock filter into a 33 gallon barrel.
12V electric fuel pump is used to fill the car.

It has served me well for three years.

Good Luck,
Jeff

I use a bowl centrifuge. It is on a timer and makes four passes for each 30 gallons of oil. I change the filters on my cars every 5000 miles when I change the oil on my cars. They never clog and never have issues. But I filter 100-150 gallons a week I do not have time for slow.

Where can I get a bowl centrifuge at a reasonable price?

reasonable
 

About $1000 is the cheapest new models that will work. But there are a few.

I pour settled WVO into the first barrel, which overflows through a triple water filter set up (30, 15, and 10 microns), into a secondary barrel which I pump into a cone bottom tank with a water pump hooked up to it. This water pump acts as a mixer (for my blend) and as a pump to my fuel nozzle when it's time to fill up the Benz. My filtration system was based on this diagram (thanks John Galt)

The only mod's I have done to my car is to ditch the little plastic fuel filter, replaced it with a cleanable metal filter, followed by another water separator/fuel filter, and then the stock MB final fuel filter. I also have added a heat exchanger recently which I am liking on these colder mornings.

I've been using a cold upflow system to clean UVO for about seven years now. It works very well and produces all the clean fuel I need.

Here's some pics of a system similar to mine:

save these pics if you're interested in this, since the frybrid site will disappear in the near future and I can't figure out how to attach pics to this site

John, I think you put me onto Coorga Quik N Dri dewatering resin. I just use a packed column now. Strainer on inlet and 5 micron sock on outlet. Crackle test is good as long as the column outlet is submerged. Otherwise the trickling stream picks up significant moisture from the air.

I think a made a PDF of that thread, as well.

Yup, I still use Q&D too. Not sure how you made a PDF of the thread, but would like to know.

Chrome browser. Go to the page, file, save as PDF. Either that or it will print to PDF.

I happened upon this system years ago (WVO/BioDiesel forum), and have no reason to look anywhere else for WVO cleaning system. There is no better way to filter/dewater WVO in my opinion. Very rarely do I ever need to change the filters in my car, the oil is so clean. Thanks John for this great system....Rich
