Technology - Future - Pervaporation for Organics recovery

The PerVap system uses a selectively permeable membrane to separate volatile organic compounds (VOCs) from a liquid stream. The system is suitable for treating low-volume waste water streams or for recovering a valuable organic compound, such as a food essence.



Pervaporation can also be used to separate organic solutions, break azeotropes (closely boiling mixtures), and dehydrate solvents, which are difficult to do through distillation or other means. Membrane Technology and Research is field testing the system, and has demonstrated VOC recovery efficiencies of 99%.
