What is Pervaporation Membrane Technology
Pervaporation is derived from two energy-efficient processes: permeation and evaporation. It achieves continuous separation of the permeable component on the properties of different dissolution and diffusion rates in the membrane module.
The process is especially suitable for the separation of near-boiling point, constant-boiling point mixtures, isomeric substrates, and compounds with poor thermal stability that are difficult or impossible to separate by the ordinary process of distillation, extraction, or adsorption.
It has obvious economic and technical advantages for the removal of trace water from organic solvents and mixed solvents, and for the separation of small amounts of organic pollutants in wastewater.
Compared with the traditional solvent recovery process, PV has outstanding features of high efficiency, low energy consumption, high recovery, convenient operation, safety, environment friendly, etc.
