Boron Removal Using Ion Exchange Membranes

A literature survey on the effectiveness of boron transport and removal across ion exchange membranes is presented. The effects of the type of membrane, the type of boron-bearing species, and operating conditions are presented. Based on the above effects, the technical applicability and feasibility of boron removal methods that involve ion exchange membranes are also discussed. Among the technologies considered are electrodialysis (ED), Donnan dialysis, and electrodeionization. In addition, the possibility for boron separation from ionic species by ED is discussed. Finally, the costs of boron removal and separation from salts using methods that employ ion exchange membranes are presented and discussed.
