Separation of a mixture in which a component is diffused through a semipermeable membrane and evaporated.

[per- + (e)vaporation (on the model of permeation).]
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.pervaporation - the concentration of a colloidal solution whose colloid will not pass through a semipermeable membrane; solution is placed in a bag of the membrane and the solvent is evaporated off
concentration - strengthening the concentration (as of a solute in a mixture) by removing diluting material
