Product Description
What is Electrodialysis (ED)?
The technology of purifying and separating substances by selective membranes and electrodes is called Electrodialysis (ED).
The method of separating different solute particles (such as ions) using the selective permeability of a semipermeable membrane is called dialysis. When dialysis is performed under the action of an electric field, the phenomenon in which charged solute particles (such as ions) in the solution migrate through the membrane is called electrodialysis.
At the beginning, it was used for seawater desalination and is now widely used in chemical industry, light industry, metallurgy, papermaking, medicine Industry, especially the preparation of pure water and the treatment of three wastes in environmental protection are the most important, such as acid and alkali recovery, electroplating waste liquid treatment and recovery of useful substances from industrial wastewater.
What is bipolar membrane electrodialysis?
The electrodialysis bipolar membrane process (BMED) is based on the unique property of bipolar membrane (BM) - electro-dissociation of water. BM effectively divides water into H+ and OH− under the influence of the applied electric field.
Bipolar electrodialysis stack consists of bipolar and monopolar (cation/anion-exchange) membranes, which convert waste salts into acids and bases.
It's used for the recovery of acid and caustic from waste salts for local use. It is an environmentally friendly technology that reduces operating costs for the wastewater treatment plant.

An Electrodialysis machine is used to purify and separate substances using selective membranes and electrodes. It is commonly utilized for seawater desalination, wastewater treatment, and the recovery of useful substances from industrial processes.
Electrodialysis works by applying an electric field to a solution containing charged solute particles, such as ions. These ions migrate through a semipermeable membrane, allowing for the separation and purification of different substances.
Electrodialysis machines are widely used in various industries including chemical, light industry, metallurgy, papermaking, and healthcare. They are especially important for pure water preparation and environmental protection through the treatment of wastewater.
Bipolar membrane electrodialysis (BMED) utilizes a bipolar membrane that can electro-dissociate water into H+ and OH− ions under an electric field. This method is effective for converting waste salts into acids and bases.
Benefits include efficient separation of ions, reduction of operational costs in wastewater treatment, and environmentally friendly processes for recovering valuable substances from waste streams.
Yes, Electrodialysis is highly effective for wastewater treatment, particularly for recovering acids and alkalis from industrial waste and reducing harmful substances in the effluent.
Absolutely. Electrodialysis is one of the technologies used for seawater desalination, effectively separating salt from water to produce fresh water.
Electrodialysis machines use selective membranes, specifically cation and anion exchange membranes, as well as bipolar membranes for specific applications like BMED.
Electrodialysis is often more energy-efficient than traditional methods like reverse osmosis, especially for specific applications such as the recovery of ions and salts from solutions.
Maintenance typically involves regular cleaning of membranes, monitoring of electrical connections, and ensuring that the system is free from blockages or fouling.
Yes, Electrodialysis is considered environmentally friendly, as it reduces waste and allows for the recovery of valuable substances from industrial processes, minimizing pollution.
Industries such as chemical manufacturing, metallurgy, papermaking, and wastewater treatment are among the primary beneficiaries of Electrodialysis technology.
Yes, Electrodialysis can recover valuable materials, such as acids and bases, from industrial wastewater, making it a cost-effective solution for material recovery.
Safety considerations include ensuring proper electrical connections, using protective gear when handling chemicals, and following operational guidelines to prevent accidents.
The time to see results from Electrodialysis can vary depending on the specific application and concentration of solutes, but it generally provides rapid separation and purification.
