Desalination/concentration of reverse osmosis and electrodialysis brines with membrane distillation
Brines produced by desalination processes such as reverse osmosis (RO), electrodialysis reversal (EDR) and ion-exchange (IX) holds pollution potential for the water environment if not properly handled. These brines contain a high water content (95–98%) and chemicals that could possibly be recovered for reuse. Therefore, direct contact membrane distillation (DCMD) which has the potential for wat...
متن کاملSelective removal of arsenic and monovalent ions from brackish water reverse osmosis concentrate.
Concentrate disposal and management is a considerable challenge for the implementation of desalination technologies, especially for inland applications where concentrate disposal options are limited. This study has focused on selective removal of arsenic and monovalent ions from brackish groundwater reverse osmosis (RO) concentrate for beneficial use and safe environmental disposal using in sit...
متن کاملHybrid electrodialysis reverse osmosis system design and its optimization for treatment of highly saline brines
The demand is rising for desalination technologies to treat highly saline brines arising from hydraulic fracturing processes and inland desalination. Interest is growing in the use of electrical desalination technologies for this application. The hybridization of electrodialysis (ED) with reverse osmosis (RO) allows high salinities (beyond the range of RO alone) to be reached while avoiding the...
متن کاملBuilding a Rechargeable Zn-Cu Battery Through Employing a Monovalent Selective Cation Exchange Membrane
The Zn-Cu battery is plagued with both the problems of Cu2+ migration into the anodic chamber as well as the problem of shape change of zinc electrodes, where both of these processes together have historically prevented this type of battery technology from being rechargeable. We herein propose using a monovalent selective cation exchange membrane (CIEM) that through X-ray diffraction experiment...
متن کاملA review of approaches to direct reverse osmosis membrane recycling: a technical, economic and environmental assessment
Background and Objective: Global market growth of reverse osmosis (RO) has led to an increase in annual disposal of membrane wastes. Therefore, evaluation of membrane waste management strategies is important to reduce their adverse environmental impacts. Due to the widespread domestic RO membrane market and their economic considerations, this study aims at investigation the direct recycling met...
