My filter/de-water set up

Postby david p » Mon Oct 06, 2008 6:32 pm

I just recently had my '02 Jetta converted with an Elsbett 1 tank kit. If you want details about the conversion (including parts), you can find them at http://www.elsbett.com/us/elsbett-conversion-technology/cars-and-vans.html.

I have a source of WVO (a Chinese restaraunt that changes the oil weekly). And I'm trying to get my filtering/dewatering system up and running. I'd like to get some feedback on my ideas if possible.


Here's what I have in mind:

1) After settling cubies for a week or two, I would pour the oil through a 100 micron pre-filter (http://www.usplastic.com/catalog/product.asp?catalog%5Fname=usplastic&category%5Fname=21329&product%5Fid=19540) into a 55 gallon drum (cut in half and about 7 feet off the ground).

2) It would flow through a pipe in the bottom to a 8"x32" 5/1 micron filter bag. (McMaster-Carr Part #5726K71)

3) Below the filter bag would be a funnel to catch the oil, then a pipe leading to the bottom of a 55 gallon drum.

4) I would pump the oil to my car from the top of the 55 gallon drum. Thus, it would work as a small up-flow system.

5) I was thinking of wrapping the 55 gallon barrel with a cable heater in order to heat it up after filtering to de-water it. My understanding is that heating it to 100-120F for 6-12 hours is what most people do. Here's the cable heater: http://www.usahardware.com/inet/shop/item/30690/icn/20-210971/wrap_on/31080.htm

Here's a link to a diagram:

Here are a couple of questions I have about the idea:

Do I need an in between filter between the 100 and 5/1?
Does upflow or heating work better to de-water? Or should I use both?

I'm a bit nervous about getting all the water out, and not real sure of how to do that effectively without costing too much money. Based on advice from coachgeo I will probably buy one of these water testing kits:

Any feedback would be great. Thanks.

Let us know if the VO output from your system passes the moisture test.
