About Electrodialysis wastewater treatment technology

electrodialysis

Electrodialysis process is a combination of electrochemical process and dialysis diffusion process. Driven by the external direct current electric field, using the selective permeability of the ion exchange membrane (that is, the cation can pass through the cation exchange membrane, the anion can pass through the anion exchange membrane), the negative and the cation move to the anode and the cathode, respectively. In the process of ion migration, if the fixed charge of the membrane is opposite to the charge of the ion, the ion can pass through; If they have the same charge, the ions are repelled, thus achieving the purpose of solution desalination, concentration, refining or purification.

Wastewater treatment Applications:

-Acid waste water process to achieve efficient recovery of acids, valuable metals and water resources;

-Ammonium chloride wastewater treatment process to achieve efficient recovery of ammonium chloride and water resources;

-Electroplating wastewater treatment process, to achieve wastewater treatment and recycling or zero waste water discharge process;

-Zirconia production wastewater treatment and recycling;

-Zero discharge of catalyst production wastewater, raw water through sand filtration and ultrafiltration into the electrodialysis system, fresh water through reverse osmosis system to get workshop reuse water, concentrated water reached 20% into the evaporation system to achieve zero discharge;

-Rare earth industry wastewater treatment;

-Pharmaceutical industry wastewater treatment;
