Purification of High Salinity Brine by Multi-Stage Ion Concentration Polarization Desalination
There is an increasing need for the desalination of high concentration brine (>TDS 35,000 ppm) efficiently and economically, either for the treatment of produced water from shale gas/oil development, or minimizing the environmental impact of brine from existing desalination plants. Yet, reverse osmosis (RO), which is the most widely used for desalination currently, is not practical for brine de...

متن کاملOut-of-plane ion concentration polarization for scalable water desalination.
We present a scalable, out-of-plane desalination approach using ion concentration polarization. A depletion boundary separates salt ions and purified water into distinct vertical layers. The out-of-plane design enables multiplexing in three dimensions, providing the functional density required for practical application. For membrane widths of 125-200 μm, and applied voltage of 5 V, the energy r...
متن کاملEnhanced Salt Removal by Unipolar Ion Conduction in Ion Concentration Polarization Desalination
Chloride ion, the majority salt in nature, is ∼52% faster than sodium ion (DNa+ = 1.33, DCl- = 2.03[10(-9)m(2)s(-1)]). Yet, current electrochemical desalination technologies (e.g. electrodialysis) rely on bipolar ion conduction, removing one pair of the cation and the anion simultaneously. Here, we demonstrate that novel ion concentration polarization desalination can enhance salt removal under...
متن کاملHybrid Supervisory Control of the Brine Heater for Multi Stage Flash Desalination Plants
Multistage Flash desalination is the most common process large-scale distillation process to produce freshwater from seawater. Its operation is energy intensive and essential for the maintenance of life support in regions with scarcity of water resources. Such plants need an efficient control system in order to be economically viable. Fortunately, the plant can be broken down into subsystems, w...
