1. Electrodialysis is usually applied to deionization of aqueous solutions.2. This fouling decreases the efficiency of the electrodialysis system. 3. The system was installed to minimize the brine from an electrodialysis reversal ( EDR ) system. 4. In 1977 Prof . Loeb invented a method of producing power by a reverse electrodialysis heat engine. 5. Other technologies for the deionization of water are, amongst others, distillation, reverse osmosis and electrodialysis . 6. Another important application for electrodialysis is the production of pure water and ultrapure water by electrodeionization ( EDI ). 7. In EDI, the purifying compartments and sometimes the concentrating compartments of the electrodialysis stack are filled with ion exchange resin. 8. In reverse electrodialysis a salt solution and fresh water are let through a stack of alternating cation and anion exchange membranes. 9. A typical industrial electrodialysis stack consists of two chambers : a product-water chamber and a concentrate-reject chamber. 10. It was at BGU that Loeb invented pressure retarded osmosis and a method of producing power by a reverse electrodialysis heat engine.
