Abstract:
A method of producing desalinated water and recovering minerals from the feedwater uses membrane separation and electrodialysis brine concentration. This process can recover all of the minerals as high purity industrial minerals, including capturing the calcium and sulfate as agricultural grade gypsum and boron as high purity boric acid. In addition the process allows the use of low cost lime or dolime to produce valuable magnesium hydroxide.
