We have been using a Kentucky Still contraption in order to reclaim our
solvents. It has done a very good job of "filtering" the junk. The only
problem is that the junk you have is still nasty. Due to local ordinances,
many people have problem getting rid of the excess resin. We're lucky in
that we can set the filtered stuff outside in the direct sunlight and let it
cure. Once cured, the resin can be disposed of by the normal means.

Subject: RE: [rp-ml] How to filter TPM?
I've never had good luck "filtering" TPM or Polyflush (what we use now.)
We've tried exposing the loaded TPM to a UV light to cure out the resin and
then filter it but I was not happy with the results. I believe that there
are some users that have this kind of a set up and it works for them. I'm
just sure what they are doing differently.
If you are using a large amount of TPM/Polyflush then you may want to
consider a distillation process to recover pure solvent from the loaded
mixture. Contact Chris Hendrix at CBG Technologies,
<BLOCKED::mailto:firstname.lastname@example.org> email@example.com. He sells
a unit that will do just what you're looking to accomplish.

Subject: [rp-ml] How to filter TPM?
Hello to all,
I would like to know what filter mesh I should use to filter used
TPM, used to clean SLA parts ( Somos resin ).
In this moment I've put a 1 um filter but it doesn't seem to filter
the disolved resin well.
Would it be better to first use UV light and then through the filter?
Any input is highly apreciated, thank you!
