How to Filter WVO For use ? - Page 2 - PeachParts Mercedes-Benz Forum

Greetings.........

The beauty of cold filtering is that any fat solids will get trapped in the filter. Might as well get them now rather than later. I just takes longer - but time is not the issue here.

The longer the oil settles - the longer the filter will last. First time I used 2 filters for approx. 40-45 gallons. But that oil had only settled for 1 week. Next batch has been settling in the elevated barrel now for 1 month. I hope to use 1 filter for the entire batch. My floor level storage barrels have been settling for different amounts of time - oldest one will get pumped - drawing from a few inches above the bottom - into the elevated barrel.

I use 5 micron string wound filters in a whole house water filter canister.

My supplies come from www.filtersource.com ask for Brian

I also make sure to add a algicide to everything - available at any marine supplies store.

Other than slow flow rate, are 1 micron bags a problem? Is 5 micron filtering enough?

If you are getting absolute 5 micron filtering you are doing really well. Many of the people who think they are filtering to 5 microns or less are really not.

The link that I posted above will take you to a place where you can buy filter bags for about $2.50 each. You have to order a minimum of 10. At that price it is well worth it.

Smooooth, thanks for sharing your experience, you posted some good information. I think you may be making this a little toooo complicated. I hereby award you the unofficial TwitchKitty Rube Goldberg award. I wish I was near Syracuse, I would come test drive some of that extra oil for you.

I need to post pictures. Stack 5 gallon buckets with lids. Cut holes in the bottom of the buckets and in the lids to pass through from bucket to bucket. Cut holes in lids to fit bag filters. Tuck fabric under lids to hold them in place.

Search the infopop biodiesel site for info.

I followed the link to www.filterbag.com, they have filters down to 1 micron. They are about 20 cents more than 5 micron. Is it worth it, over kill, or is 5 micron plenty?

My final filter is a 0.5 micron bag I got from Greasel for $13.00. This is overkill, I know. I have a big settling tank - over 200 gallons capacity, then a Dana fabric filter, pump by hand through a paper cartridge (10 microns?) then pour into the final bag. I'm sure the clogging I'm getting in the car filters is fungus and/or gunk in the tank dissolved by wvo. I'm going to add Biobor or something like it, keep changing filters, and hope it clears up.

I will go with the 1 micron filter then. Don't want any chicken bones in the fuel tank!!!

Thanks for the picture R Leo. i'm off to find a barrel

Cheers,

Oooooouuuuuccccccchhhhhhh......... =8^)

All in good fun. Unfortunately, and I get this from my father, if you ask me what time it is - I might try and tell you how to build a watch.

I'm a sailor and have a diesel engine in my boat. I'm getting ready to experiment with WVO and there seems to be some marine equipment that might help (I also get a huge discount on the stuff). One that is interesting is a filter funnel - maybe it could be used for initial WVO. Any one care to take a look at this article and comment?

One of those would likely work quite well for prefiltering. Although depending on how cruddy your oil comes.. it might clog up very fast.

I want to be able to cold filter my collected oils without having to constantly monitor and attend to the activity like I currently do. I'm thinking that I can gravity feed a couple of bag filters in housings on a manifold and, as long as I don't try to put more in the top tank than the bottom tank can hold, it should be a set and forget situation.

I've searched the net and come up with nothing when it comes to an inexpensive bag filter housing so, here's my idea for a home-grown filter housing. It's made from standard 6" PVC tubing pieces and some home machined goodies. The cover plate and retaining flange could be cut (with a sabersaw) from 3/4" thick nylon kitchen chopping board. It isn't shown in the drawing but, depending on the bag filter used, an adapter ring made from the same material would be cut to fit on the inside top edge of the 6" tubing with a hole in it for whatever size bag you were using. A homemade bag support that fit against the top edge of the 6" tubing would function the same way too.

The way I'm doing it.

What you've got here looks very similiar to a whole house water filter set up. Why not use something like that?? How many microns is a whole house filter?
I don't know if that setup would work or not, thats why I'm askin'!

Bill

All the whole house filters I've some across are the cartridge type requiring elements costing somewhere between $3-$6 each. Because of the variable nature of the oil I'm collecting and its propensity to completely plug my filters on occasion, I prefer a reuseable, cleanable, bag-type filter setup over a one-shot $5.00 cartridge. I may have to make my own bag filters to fit my housing but that's not much of a hardship when you consider their potential lifespan.

If I lived in a more industrial area, ie Houston or San Antonio, I might be able to ferret out suitable used bag filter housings. However, I don't have the time to mess with that right now; this will have to do.
