Core Principle of Electrodialysis
The core of electrodialysis technology lies in the combination of electric field and selective membrane technology, with the specific principle divided into two parts:
1. Driving effect of DC electric field
Under the action of a DC electric field, anions and cations in the solution move directionally: cations migrate toward the negative electrode, while anions migrate toward the positive electrode.
2. Selective sieving effect of ion exchange membranes
Two types of ion exchange membranes are used in the system to achieve ion separation:
Cation exchange membrane: Only allows cations (e.g., Na+, Ca2+, Mg2+) to pass through, while blocking anions.
Anion exchange membrane: Only allows anions (e.g., Cl-, SO42-) to pass through, while blocking cations.
Diffusion Dialysis
Diffusion Dialysis Membranes
Including acid recovery diffusion dialysis membranes and alkali recovery diffusion dialysis membranes.
Diffusion Dialyzers
Equipment for separating alkali (acid) by arranging diffusion dialysis membranes, dialysis chamber separators, and diffusion chamber separators in a certain order, placing water distribution plates on both sides and clamping with clamping plates.
Working Principle
The diffusion dialysis process takes concentration difference as the driving force, and uses the selective permeability of (anion) cation exchange membranes to (acid) alkali and high retention of salts or other components to separate (acid) alkali from salts or other components in the solution. The separated alkali (acid) solution is reused in the production process.

Bipolar Membrane Electrodialysis
Bipolar Membranes
Composed of a composite of anion membrane layer and cation membrane layer, which can perform electro-dissociation of water or alcohol under the drive of an electric field.
Equipment Structure
Assembled by alternating bipolar membranes, anion membranes, and cation membranes, separated by separators, and equipped with electrode plates, polar plates and end plates.
Working Principle
Water is dissociated into H⁺ and OH⁻ ions, which combine with corresponding anions and cations respectively to form acids and alkalis. At the same time, wastewater desalination and acid/alkali preparation are realized.
