Mass Transfer Processes: Modeling, Computations, and Design

Chapter 30. Electrodialysis and Electrophoresis

Learning Objectives

After completing this chapter, you will be able to:

• Understand the principles behind separation by electrodialysis and some of its applications.

• Classify the types of membranes used in the process and understand the operation of a bipolar membrane.

• Design and evaluate a electrodialysis system based on a simple model.

• Understand how two charged species can be separated due to the differences in their relative mobility by the electrophoresis method.

• Review the flow and field arrangements in some common electrophoresis units.

• Develop and solve simple models for electrophoresis and apply these for preliminary design of a device.

Electrodialysis refers to mass transport through ...
