Curved electrodialysis membranes: an innovative approach to enhance ion separation in EDMEM stacks.

摘要: AbstractThe predominant driving force for ion separation in electrodialysis membrane (EDMEM) stacks is the electrical potential gradient. Nevertheless, excessive gradient, besides higher energy consumption, could lead to other detrimental impacts such as concentration polarization and fouling. The orientation of electric field lines with respect main flow stream would instead be changed offset effect drawbacks. present study introduces a potentially innovative technique utilizing curved EDMEM by changing that it result better stack performance. Mathematical simulations based on analogy between heat conduction have been employed which confirmed effectiveness membrane. A mathematical model has also developed characterizes performance membranes.
