Overview

Electrodialysis concentration equipment for industrial wastewater treatment has a wide range of applications. It is used in water desalination and desalination, seawater concentration to produce refined dairy products, fruit juice deacidification and purification, and the production of chemical products. It can also be used in industries such as food and light industry to produce pure water, and in industries such as electronics and medicine to produce high-purity water for pre-treatment. The primary softening and desalination of boiler feedwater converts brackish water into drinking water.

Product Details

　　Electrodialysis concentration equipment, industrial wastewater treatment equipmentWorking Principle:

Electric driven membrane separation equipment is a physical and chemical process that utilizes the selective permeability of electric driven membranes to transfer ions from one part of water to another under the action of an external direct current electric field. The electrically driven membrane separation desalination device utilizes the electrodialysis process in multiple compartments to achieve the goal of desalination of water.

The electrically driven membrane separator consists of main components such as separators, electrically driven membranes, electrodes, and clamping devices. Electric driven membranes have selective permeability to ions of different charges. The cation membrane only allows cations to pass through and prevents anions from passing through; The anion membrane only allows anions to pass through and prevents cations from passing through.

Under the action of an external direct current electric field, ions in water undergo directional migration. Due to the fact that the electrically driven membrane separator is composed of multiple compartments, the anions and cations in the dilute chamber migrate to the adjacent concentrated chamber, thereby desalinating the saltwater.

　　Electrodialysis concentration equipment, industrial wastewater treatment equipmentElectrodialysis is a naturally occurring physical phenomenon. For example, when two types of water with different salt contents are separated by a permeable membrane, the dielectric ions of the water with higher salt content will diffuse through the membrane to the water with lower salt content. This phenomenon is called electrodialysis.

This type of electrodialysis is caused by different salt concentrations and is called concentration electrodialysis. The electrodialysis process is related to the size of the concentration difference. The larger the concentration difference, the faster the electrodialysis process, otherwise it will be slower. Because it is driven by concentration, the diffusion speed is always relatively slow.

If you want to accelerate this speed, you can apply a direct current electric field on both sides of the membrane. Electrolyte ions under the action of an electric field; It will quickly pass through the membrane and undergo a migration process, which is called electrodialysis.

The method of using the selective permeability of a semi permeable membrane to separate different solute particles (such as ions) is called dialysis. The phenomenon of charged solute particles (such as ions) in the solution migrating through the membrane during dialysis under the action of an electric field is called electrodialysis.

The technology of purifying and separating substances using electrodialysis is called electrodialysis, which was first used for seawater desalination and is now widely used in the chemical, light industry, metallurgy, papermaking, and pharmaceutical industries. It is particularly important for preparing pure water and treating three wastes in environmental protection, such as acid and alkali recovery, electroplating waste liquid treatment, and recovery from industrial wastewater.
