Abstract
The present invention relates to a process for at least partial dehydration of an aqueous composition, in which said composition to be dehydrated is brought into contact, through the intermediacy of a microporous hydrophobic membrane, with a receiving phase whose water activity is substantially lower than that of the aqueous composition and in which the aqueous composition, at least partially dehydrated, is recovered. The invention also relates to devices enabling the process to be implemented, especially continuously.
