Abstract
An exemplary embodiment of the present disclosure provides a method for purifying salt water. The method comprises the steps of removing at least a portion of salt in the salt water to form a potable water and introducing the at least a portion of the salt removed from the salt water to a water feed.
Claims27
A method comprising:
- introducing a first feed stream with an initial ion concentration of anions and cations to a cell;
- introducing a second feed stream with an initial ion concentration of the anions and the cations to the cell, wherein the initial ion concentration of the first feed stream is higher than the initial ion concentration of the second feed stream;
- transferring, through reverse electrodialysis, a portion of the anions and the cations from the first feed stream to the second feed stream;
- extracting salinity-gradient energy from a difference in ion concentration between the first feed stream and the second feed stream;
- and
- transferring, through electrodialysis, a portion of the anions and the cations from the first feed stream to the second feed stream.
