Add this thought into the mix...
It is much more energy efficient to "atomize" (so-called) water into a
mist or fog than it is to perform any form of true distillation. The
advantage is perhaps in the range of orders of magnitude -say 100-1 (guess).
Problem is - this does not imply that you get rid of any minerals since
the atomized water mist will have the original mineral content entrained
in the small droplets.
However ---- and this more of a query - is there any lower size range
which is available for very small droplet size - which will expel some
of the mineral content when used in a situation where other forces are
applied?
Thinking in particular about spraying an extremely fine mist through a
crossed magnetic or magnetic-electic field such that an MHD effect will
concentrate minerals in one vector and allow partially purified water to
exit in another....

Interesting comparison between R-O and MSF Triple flash distillation
methods of desal. Thankfully, we have both processes. Each process has
it's benefits and advantages.
Our tiny manufacturing company struggles with research in methods of
reducing the mineral content of brackish and seawater prior to
entering the pre-filters of the R-O membrane trains. One of the
functions of a water vortex is it's ability to create a vacuum when
the spin is induced by mechanical means. We have closely studied the
MSF processes and the comparative efficencies vs R-O, in particular ,
the temperature differentials between the flash stages. One of our
test setups include a two stage Lazell Flow Nozzle ( expander rather
than a throat venturi effect). The purpose is to determine if we can
get the flash without the added cost of heating.
Hmmm.. a sort of a hybrid MSF- RO.. (sounds like the lyrics to RAP
music. <grin>)
