Electrodialysis (ED): A Deeper Dive

Electrodialysis is a membrane-based separation process that utilizes an electric field to separate ions from a solution. This section provides a detailed explanation of the working principle of ED, highlighting the role of different components:

• Membranes: ED systems use alternating layers of cation and anion exchange membranes. These semi-permeable membranes allow specific ions to pass through while blocking others.
• Electric Field: An electric current is applied across the membrane stack, creating an electric field that drives the movement of ions.
• Electrodes: Electrodes are placed at the ends of the stack to conduct the electric current.

The chapter also covers the various factors influencing the efficiency of ED, such as:

• Membrane properties: The selectivity and permeability of the membranes influence the separation process.
• Current density: Higher current density results in faster ion transport but can also lead to increased energy consumption.
• Feed water quality: The concentration and type of ions in the feed water affect the performance of the ED system.
