Capacitive deionization (CDI) is a promising desalination technology based on electrosorption the surfaces of microporous electrodes. However, low total dissolved solids (TDS) in water restricts its efficacy. In this work, we develop theory capacitive spacers (CS) CDI. The investigations reveal mechanism that call ohmic charging; is, resistive losses spacer region drive adsorption CS. As conseq...

Flow-electrode capacitive deionization (FCDI) offers an electrochemical, energy-efficient technique for water desalination. In this work, we report the study of carbon-based FCDI, which consists one desalination chamber and salination applies a carbon nanomaterials-based flow electrode that circulates between cell anode cathode, to achieve fast, continuous process. Five different nanomaterials ...

nanofiltration-based separation processes have found diverse applications in industrial and environmentalproblems recently, due to several advantages such as lower energy requirement and elevated flux ratescompared with their reverse osmosis (ro) counterparts. several attempts have been made for modellingnf-based separation processes ranging from rigorous space-charge approaches to simpler irre...

Abstract Available freshwater resources are becoming harder to obtain due climate change, population growth, industrial development, and water pollution. The main technologies in the field of wastewater desalination include reverse osmosis, electrodialysis, thermal distillation, adsorption etc. Capacitive deionization technology (CDI) belongs a novel electrochemical with low energy consumption ...

Introduction Capacitive deionization (CDI), which is ion electrosorption onto the surface of porous materials to remove ions from aqueous solutions, may serve as an energy-efficient alternative for the desalination of brackish water comparing with conventional desalination methods such as membrane separation and thermal distillation [1]. The CDI process operates at low direct voltages. Ions ads...
