4 Ton/H Alkaline Recovery Industrial Wastewater Treatment Electrodialysis System

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.

Homogeneous Membrane Electrodialysis: Including anion exchange membranes and cation exchange membranes.

Electrodialyzers: Assembled by alternating anion membranes and cation membranes, separated by separators, and equipped with electrode plates, polar plates and end plates.

Working Principle: Directional migration of ions under the action of an electric field and selective permeability of ion exchange membranes.

Application of Homogeneous Membrane Electrodialysis in Industrial Production:

This system features high efficiency, energy saving, environmental protection, and easy installation. It is suitable for schools, parks, roadsides, factories, squares, etc.

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 Hydrogen Ion and Hydroxide Ion 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.
