More pressure across the sheet will definitely increase throughput
but as one member pointed out the sheet can only take so much. No a
plastic barrel would be worse. And no the size of the pump is not so
much of a factor. I can implode a steel drum with an aquarium pump,
although it will take

For vacuum use, I would construct a filter by using a pipe with tons of holes drilled in it and wrap it with the sheet or felt or what have you, Then place this pipe inside a larger pipe as a housing. The inlet would be to the outer pipe and then the pipe with the holes becomes a

I'm not sure exactly what product you are talking about but if you are
thinking about something which is supposed to be disposable please
don't. Whatever we build and use should be made to last and be
emptied, washed and re-used. This is not a throw away world and we
have to get away

Umm, don't quite understand. Push air in to get air out? Or are you
referring more to an accordian or bladder style container, compressed
then forcibly expanded to create a vacuum?

Hi Hal
Thank for showing the very nice good picture and your very good work.
Some filter aids use on the cloth and some height like cofee filter can improve the filteration quality.
In the case of the crude oils , the impurity of small colloidal particles act as the filterationmaking
Hmmm, just when I start to think I know something
Let me explain where I am at with this and it may save me endless hours
and $. I reprocessed some bio based on JtF reprocess instructions, and
had 0 Glycerin drop out. Possibly the Bio is fine, but it was darker
than that I made from

YES! Thank you for the great idea! I will ask my wife to help me make
one soon. I have been pondering long and hard on this part of the process.
Why bother to filter it at all? If you're running SVO, sure, but for
making biodiesel there's no need.
I seldom see flotsam in WVO, if so just scoop

OR, vacuum the bottom by pushing the air out of it rather than pulling. Vacuum's are soI dunno...ineffecient.

I wonder if you couldn't improve the speed of the it if you made it a
vacuum filtration process? Hook up a vacuum pump to an opening on the
side of the barrel, set high up so it doesn't actually remove oil, and
turned it on to create a decreased pressure within the barrel to draw
the oil through
Careful. Even a modest vacuum will result in tremendous forces
developing on the large surface area of that drum which is way too
wimpy metal for the job as a vacuum vessel. You will end up crushing
the drum and making a huge mess!

Hello Hal,
Great idea and reusable as well.
Thanks,

like it! I use old pillowcases in the same way with 5 gallon
buckets for the initial WVO filtering, but yours is prettier!

True. What if it were more of a pulsed vacuum, based upon rate of flow?
A little vacuum assistance here, a little vacuum assistance there; what
I was operating off of was the principle behind a little piece of lab
equipment we used in high school, in which running water was used to
generate
Why a vacuum? Jeeze why a vacuum? Pumps are so much cheaper!
2 stage, barrel on a barrel, filter in the middle. Air tight @ the
filter, airtight @ the top. A medium sized fish aquarium should be able
to generate enough pressure (or an air compressor, they can be had for
cheaply enough), pushes
