Electrodialysis Technology for High-Purity Phosphorylcholine Desalination
A recent industrial desalination project using electrodialysis technology has demonstrated stable and efficient purification performance for phosphorylcholine-related products.
The system integrates an AIO416-500S alloy membrane electrodialysis unit together with a 416-type heterogeneous membrane system, allowing flexible operation under different production capacities.
During operation, feed solution conductivity was successfully reduced from approximately 50 mS/cm to below 60 μS/cm, achieving a desalination rate exceeding 99% while maintaining low product loss. Importantly, the electrodialysis process had minimal impact on product pH, helping preserve material stability throughout purification.
Compared with conventional desalination methods, electrodialysis offers several advantages for fine chemical and pharmaceutical intermediate applications:
✔ Low wastewater discharge
✔ Low operating pressure
✔ Compact footprint
✔ Lower energy consumption
✔ Stable continuous operation
The project has now entered stable production operation, with treatment performance fully meeting customer expectations.
As industries continue seeking cleaner and more resource-efficient purification technologies, electrodialysis is becoming an increasingly valuable solution for high-value product desalination and process optimization.
