Abstract
A system and method of desalinating a brine stream are provided. The multistage desalination process with carbon dioxide capture recovers valuable products where the reject brine is passed through seven stages. In each stage, a specific metal ion is recovered. In stage 1, a ˜100% recovery of magnesium ions as magnesium hydroxide solid was obtained by chemical reaction with ammonia solution. In stage 2, Nareduction, as sodium bicarbonate, and COuptake was achieved. In stage 3, electrocoagulation (EC) was used to recover sulfate ions as pure calcium sulfate solid and to regenerate NHas ammonium hydroxide. In stage 4, CaO was added to the treated brine. In stage 5, more recovery of NaHCOwas attained by adding ammonium bicarbonate, while in stage 6, the treated brine mixture was passed through another modified Solvay process. In stage 7, EC was again used to recover CaClsolution and NHcompounds.
