Abstract:
 Polar molecules orient and migrate in an asymmetric electric field. Providing an asymmetric electric field across a membrane in a membrane distillation process for water treatment, thetransport of water will be driven by the pressure gradient and the electric potential gradient, and thus the water permeation will be accelerated in the pressure-electric coupled field. Salts and macromolecules are nonvolatile and thetransport of these solutes willnot be affected by the electric field. Therefore, by applying the asymmetric electric field, both the water flux and the separation can be improved. The mass transport of water molecules in the coupled field was investigated, andthe applications of the asymmetric electric fieldenhanced membrane distillation for desalination, treatment of dye solutions and concentration of thermal-sensitive compounds were alsoevaluated.
