This is on a large scale with zeolyte (sp?) beads with porous structures. Superheated vapor is passed through the bed of beads, and the water gets "stuck" in the pores. The water is then forced out by recircing some of the finished product back through the beds. It works ok, but makes for a control headache.

Sounds like a similar process to the average water softener albeit at higher temps. Thanks for the description.
