Abstract The lamellar graphene oxide (GO) membranes could offer well-defined 2D nanochannels for fast water permeation and excellent ions rejection. In this work, lamellar GO membranes were constructed by stacking GO nanosheets layer-by-layer via molecular simulation. The effect of hydroxyl and epoxy groups as well as their content on the desalination performance in lamellar GO membranes were investigated by molecular dynamics simulation. The transport and separation mechanisms of water molecule...

Abstract New hybrid membrane was inspired by biomimicking the water harvesting system in the back of fogstand beetle. Therefore, efficient hydrophobic material with hydrophilic chitosan (CS) islands was produced by the covalent attachment of chitosan to the hydrophobic surface of PVDF membranes. The attachment of CS molecules allows upgrading the membrane permeability and antifouling properties. Employing the “grafting to” approach, CS was anchored to pre-activated PVDF-membranes by urea linker ...

Abstract Global estimates of electricity generation from coastal salinity gradient energy resources rely on the underlying assumption that these gradients are spatially and temporally stable. Refining these estimates requires a better understanding of coastal variations in water properties and their impact on power production. This study investigated power output in reverse electrodialysis (RED) cells by coupling seawater samples collected from three different sites along coastal North Carolina ...

Abstract In this study, we evaluated steady state power generation performance of a bench-scale RED stack with an effective membrane area of 40 m2 under different flow rate conditions using brine discharged from a seawater desalination plant and water discharged from a sewage treatment plant. Constant current operation was enabled to evaluate the steady state power output of the stack as the salt concentration profile inside the stack approached equilibrium. In addition, external current loading...

Abstract The utilization of seawater for drinking purposes is limited by the high specific energy consumption (SEC) (kW-h/m3) of present desalination technologies; both thermal and membrane-based. This is in turn exasperated by high water production costs, adding up to the water scarcity around the globe. Most technologies are already working near their thermodynamic limit, while posing challenges in further SEC reductions. Understanding the current energy status and energy breakdowns of leading...

Abstract Capacitive deionization (CDI) has emerged as a novel desalination technology due to its cleanliness and low energy consumption. Despite being based on the principle of an electric double layer for ion adsorption on porous carbon materials, the inevitable faradaic reaction and the existence of co-ion repulsion reduce the charge efficiency (CE), leading to a low salt adsorption capacity (SAC). Herein, an integrated membrane electrode (IME), prepared by spray-coating a thin layer of an ion...

Abstract Pressure retarded osmosis (PRO) has been considered as a potential technique to harvest salinity gradient energy (or osmotic energy). The SWRO-PRO hybrid system is one of the viable ways of implementing PRO technology to resolve problems associated with seawater desalination. However, relatively few works have been attempted in pilot scales, which are inevitable for the scale-up and practical application of the SWRO-PRO technology. In this context, this paper reports the pilot study res...

Abstract Increasing demand for affordable desalinating water has stimulated the vigorous development of reverse osmosis (RO) membranes. To date, the performance of polymeric membranes is limited by the permeability–selectivity trade-off: more permeable membranes lead to a less ideal selectivity and vice versa. Significant efforts have been made to identify new classes of ultra-permeable nanoporous membranes, but such trade-off can still be commonly observed. In this study, we identify the key ro...

Abstract Despite significant advances in reverse osmosis (RO) applications, membrane fouling is an inevitable problem that reduces the quantity and quality of produced water and is associated with reducing the energy efficiency of the entire system. The aim of this study was to expand our understanding of the modified fouling index (MFI), which is a reliable tool used to provide insight into the fouling characteristics of the RO process in advance. The applicability of MFI to predict RO membrane...

Abstract In this study, the polyamide (PA) layers of commercial thin-film composite (TFC) forward osmosis (FO) membranes were coated with glutaraldehyde cross-linked polyvinyl alcohol (PVA) hydrogel comprising of graphene oxide (GO) at various loadings to enhance their fouling resistance. The optimal GO concentration of 0.02 wt% in hydrogel solution was confirmed from the FO membrane performance, and its influence on membrane antifouling properties was studied. The properties of the modified mem...
