Waste water treatment and selective recoveries of small amounts of solutes from solvents are still one of the main challenges in downstream processing. Pervaporation is one of the promising and modern separation methods - a membrane separation process that employs dense, non-porous membranes for selective separation of dilute solutes from a bulk solvent. The pervaporation separation technique is widely used on industrial scale as an organophilic pervaporation for selective organic permeation of organic substances from dilute aqueous solutions (a recovery of organics from fermentation broths or removal of organic contaminants from effluent streams). It is also applied as a hydrophilic pervaporation for selective water removal from organic media (solvent dehydration) and for the separation of various organic mixtures (azeotropic mixtures or mixtures with close boiling points).
