Electrodialysis with monovalent selective ion exchange membranes for organic acid separation
Discover a novel electrodialysis method using monovalent selective ion exchange membranes to enhance separation of organic acids from mineral salts, achieving higher purity levels. Ideal for industries requiring precise separation techniques.
Overview
This innovative solution leverages electrodialysis with monovalent selective ion exchange membranes to significantly enhance the separation of organic acids from mineral salts. This approach manipulates pH and other operating conditions to achieve higher purity levels than traditional methods. The technology is particularly beneficial for industries that require precise separation techniques, such as the pharmaceutical and food industries, where high purity and yield are critical.
Technical specifications
The core of this technology is the use of monovalent selective ion exchange membranes in the electrodialysis process. Traditional membranes achieve a purity of 90-95% with a yield of around 95%, but the use of monovalent selective membranes promises even higher purities. Key features include:
- Separation of monobasic lactic acid from polybasic citric acid
- Enhanced purity through pH manipulation and membrane selection
- Potential integration with upstream ultrafiltration (UF) or nanofiltration (NF) for improved results
Technology readiness level
Currently, the technology is at TRL 4, signifying that it has been validated in lab environments. Future steps include testing with broth samples and optimizing conditions to further improve performance and readiness for commercial applications.
