20130062207 | METHOD AND SYSTEM FOR DISPOSAL OF BRINE SOLUTION - A reverse electrodialyzer has a plurality of concentrated compartments and diluted compartments arranged alternatively. The concentrated compartments and the diluted compartments are formed by successive alternatively arranged oppositely charged ion exchange membranes between two electrodes. A brine solution is fed into the concentrated compartments, and a diluted solution is into the diluted compartments, the salinity of the diluted solution being lower than the salinity of the brine solution. Ions from the brine solution in the concentrated compartments pass through the membranes to the diluted solution in the diluted compartments forming a diluted brine solution in the concentrated compartments. The brine solution is extracted from the concentrated compartments for disposal. An electrical energy is produced due to the concentration difference of the brine solution and the diluted solution. | 03-14-2013 |
