Bipolar Electrodialysis Membranes




Bipolar membranes are a new type of ion-exchange composite membrane. Under the influence of a direct current (DC) electric field, the membrane causes water to dissociate, generating H+ ions on one side and OH- ions on the other. These ions combine with the respective cations and anions passing through the cation and anion exchange membranes, producing acid and base solutions. This process allows for the direct production and concentration of acids and bases from salts.




Key Features:




High Energy Efficiency: Produces acids and bases directly with low energy consumption.

Strong Chemical Resistance: Highly resistant to strong acids and bases.

Good Mechanical Performance: Offers flexibility and high mechanical strength, ensuring a longer lifespan.




Applications:




Production and recovery of organic acids, inorganic acids, and bases.

Flue gas desulfurization wastewater treatment, particularly for handling and recovering salts from wastewater.

Industrial and radioactive wastewater treatment, including desalination and recovery of valuable components.

Acid and base production and recovery from organic and inorganic salts, as well as treatment of waste acids and bases.

Preparation of high-purity and ultrapure water.




Homogeneous Electrodialysis Membranes




In a homogeneous membrane, under a DC electric field, cations move through the cation exchange membrane toward the negative electrode, while anions pass through the anion exchange membrane toward the positive electrode. By separating cations and anions, the process creates a desalination chamber and a concentrated solution chamber, achieving either desalination or increased salt concentration.




Key Features:




Fast Desalination: Quickly removes cations and anions from water.

High Desalination Efficiency: Achieves efficient desalination in a short time.




Applications:




Brine concentration and desalination, including seawater desalination and salt production.

Desalination of organic compounds and treatment of organic wastewater.

Drinking water production by desalinating brackish water and seawater.

Concentration and wastewater recovery, suitable for pre-concentration before evaporation and recovery of valuable components from wastewater.

Production of high-purity and ultrapure water.

Ion separation technologies for isolating specific ions from substances.
