【Application Fields】

Chemical & Bulk Chemical Production
Large-Scale Organic Acid Production: A classic successful application of electrodialysis. Used in the production processes of hundreds of thousands of tons of products like gluconic acid, amino acids, citric acid, and lactic acid. It replaces the traditional calcium salt method, enabling direct acid conversion and purification, significantly reducing waste residue (calcium sulfate), lowering energy consumption, and improving product purity.
Chlor-Alkali Industry: Serves as a core unit for producing sodium hydroxide and hydrochloric/sulfuric acid.
Wastewater Resource Recovery: Large-scale recovery of by-products like ammonium sulfate and ammonium nitrate from industrial wastewater, turning waste into valuable resources and achieving both environmental and economic benefits.
Power, Metallurgy & Zero Liquid Discharge (ZLD) Engineering
ZLD for Thermal Power/Coal Chemical Wastewater: Acts as the core concentration process stage, treating reverse osmosis (RO) concentrate to reduce the overall ZLD plant investment and operating costs.
Hydrometallurgy: Used for the large-scale extraction and purification of metals like cobalt, lithium, nickel, and copper. Enables continuous separation and concentration of target metal ions from vast leachate pools, improving recovery rates and product quality.
Radioactive Wastewater Treatment: Treats low-level radioactive wastewater from nuclear power plants, concentrating it and reducing waste volume for subsequent safe disposal.
Food & Beverage Industry
Whey Processing: Used by large dairy companies for the large-scale production of desalinated whey powder, a base ingredient for high-value products like infant formula.
Juice Deacidification: Used in large juice processing plants for the industrial-scale adjustment of taste in products like wine or citrus juice.
Monosodium Glutamate (MSG) Purification: Used in MSG production to remove impurity ions.
Biotechnology & Pharmaceutical Fermentation
Antibiotic & Vitamin Extraction/Purification: In downstream processing of fermentation broth, large-scale electrodialysis replaces traditional ion-exchange resins for continuous desalination, reducing acid/alkali consumption and wastewater discharge.
API Desalination: Provides GMP-compliant purification for large-scale Active Pharmaceutical Ingredient (API) production.
Seawater Desalination & Brackish Water Utilization
High-Salinity Brackish Water Desalination: In specific regions, for groundwater with extremely high salt content, ED technology is favored due to its strong adaptability to high salinity feed and relatively lower membrane fouling propensity.
Salt Production via Seawater Concentration: Pre-concentrating seawater in ED before solar evaporation in salt pans significantly improves salt production efficiency and land use.
