Electrodialysis

Electordialyzer is a core membrane separation technology in our advanced Electrodialysis System. It utilizes a direct current electric field to drive ions and achieves separation through ion exchange membranes. This process is the foundation of both standard Electordialyzer and Electrodialysis Reversal (EDR) systems, which use an electric potential difference as the driving force for applications like brine concentration system operations and wastewater demineralization treatment.

As a leading electrodialysis equipment supplier, our industrial electrodialysis unit technology is widely applied in lithium hydroxide production process and electrodialysis for lithium concentration from salt lakes. Beyond lithium, our systems provide organic acid purification technology and a highly efficient glycine desalination method. We also specialize in acid recovery from wastewater and treating challenging streams like HIRO (High Recovery Reverse Osmosis) concentrate as part of a comprehensive ZLD (Zero Liquid Discharge) electrodialysis strategy.

We provide enterprises with full-process solutions, including separation, concentration, and desalination, often featuring a custom electrodialysis system design to meet specific needs, with support for long-term performance including ED stack replacement.
