  • Desalting aqueous streams via filled cell electrodialysis
    Patent number: 6017433
    Abstract: The invention is a process for desalting aqueous solutions, which are initially acidified to a pH of about 3 or less. Then, the acidified solution is fed into a desalting compartment of an electrodeionization cell which contains a suitable ion exchange material and is isolated from an adjacent concentrating compartments by an anion and a cation exchange membrane. The concentrate compartment contains a netting or another suitable material that promotes turbulence in a flowing feed stream. Water is supplied to the concentrate compartment. A DC current passes through the electrodeionization cell to produce a substantial desalination of the feed solution. A less acidic desalted solution and a concentrate waste solution are withdrawn from the electrodeionization cell.
