Electrodialysis
StanTech Electrodialysis:
Process description in principle
Electrodialysis is a process in which ionic species from an aqueous solution of a hydraulic circuit are transported into another hydraulic circuit by means of an electrical potential difference across a suitable arranged scheme of cation and anion selective membranes, a so-called stack.
Selected applications:
- Water desalination
- Desalination of whey
- Desalination of proteins, separation of proteins
- Salt splitting (bipolar membrane technology)
- Diffusion dialysis
Components of specific StanTech interest:
- Membranes that are stable in regard of chemical and thermal attacks
- Membranes with high selectivities
- Bipolar membranes
- Two-, three- and four-circuit ED-stacks, flat sheet design with manifold open and closed hydraulic systems
