Electrodialysis processes using an organic solvent for separating dissolved species

A method of separating dissolved salts from a feed stream comprising:

• passing water through an electrodialysis unit configured to separate dissolved salts from a feed stream, wherein the electrodialysis unit comprises an inlet feed stream, an inlet brine stream, an outlet product stream, and an outlet brine stream;
• routing the outlet brine stream of the electrodialysis unit to a precipitation tank to allow the dissolved salts to precipitate from solution, wherein the precipitation tank comprises an inlet stream and an outlet supernatant stream;
• and
• routing the outlet supernatant stream from the precipitation tank to the electrodialysis unit, wherein the inlet brine stream of the electrodialysis unit comprises the outlet supernatant stream of the precipitation tank,
• wherein the inlet brine stream and the outlet brine stream of the electrodialysis unit comprise an organic solvent.
