Filtering and drying are entirely possible...  You can look on the web for
firms that sell gear to do this, and then get ideas on how to build your own
treatment rig.

Drying: heat, vacuum, dessicant....  Oil can be heated to hotter than
100C.... Pull a vacuum and it "slowly" degasses, gentle agitation in a
vacuum might help, at least to bring new oil to the surface.  Silica gel
(e.g.) or metallic sodium can be used to adsorb or react out the water.

Filtering is a bit trickier, because you need to filter out really, really
tiny particles... A regular old automotive type filter isn't going to hack
it, but if you can find some very high performance filters, you're all set.
(of course, the filters might cost more than brand new oil...)

Or, rig yourself up a little oil test set (NST, microammeter, test cell,
variac) and see what the breakdown voltage of your oil is.  It might be more
than "good enough"
