So you can't spin the still?
Centrifugal fractionation is very well known!
So is GCC, to go off on a tangent

Net solar insolation at UV wavelengths is very strong - how strong and how
effective?
I dunno, and I suggest this would be a nice simple experiment to perform.

why not vacuum distillation/fractionation...

Because we're talking about purifying water condensed from the air -- that
is, most contaminants will be ones that move easily from vapor to liquid
and back, and won't be removed easily by distillation processes.

Also, it's not simple to build a still that will work in free fall --
gravity is very convenient for separating liquid from gas. There are
ways of dealing with this, but it adds serious complications.

and Solar UV.

Quite apart from the fact that it's unavailable when your vehicle is in
Earth's shadow or is pointed the wrong way, there is a more fundamental
problem that it doesn't penetrate water worth a damn, so arranging that
water-borne contaminants get thoroughly exposed to it is difficult.
