Summary: The hypothesis states that cation exchange membranes (CEMs) face fouling issues when used in desalination of wastewater from the oil and gas industry, affecting their performance. Fouling experiments were conducted on commercial CEMs with varying solutions, demonstrating that fouling primarily occurs in the presence of polyelectrolytes. The study found that changing the direction of current could remove the polyelectrolyte fouling layer, with precipitation occurring on the opposite side of the membrane.

Summary: White carbon black (WCB) is an important silica product widely used in industries. However, the production of WCB using the precipitation method generates a large amount of wastewater containing sodium sulfate and silica. This study explores the use of electrodialysis (ED) as a treatment method for WCB wastewater. The results demonstrate that ED is an effective, low energy-cost, and reliable process for treating WCB wastewater.

Summary: The study on fouling dynamics of APAM towards AEM during ED reveals that monitoring the variation of the solution and membrane properties can help understand the fouling process. Deposition of APAM gradually hinders current transfer, leading to the formation of a gel layer and blockage of free volume, resulting in increased membrane resistance. Water splitting causes significant pH variation, altering the particle size of APAM and accelerating fouling formation.

Summary: Ion exchange membranes play a crucial role in various separation processes, but their performance is significantly limited by fouling issues caused by the heterogeneous and multivalent ionic composition of natural feedwaters. Efficient membrane cleaning strategies are essential to control and mitigate the impacts of fouling phenomena, with a focus on membrane type, characterization, and target application. Promising membrane cleaning approaches, including physical, chemical, and mechanical methods, are summarized and discussed in this review.

Summary: This study investigates the impact of surface roughness and hydrophilicity on membrane fouling using two types of ion exchange membranes. The commercially available membranes have rough and hydrophilic surfaces, while the lab-made membranes have smooth and hydrophobic surfaces. The fouling tests confirm that electrical attraction is the main cause of membrane fouling, with anionic and cationic foulants affecting anion and cation exchange membranes, respectively. The results show that a rough surface has a higher fouling tendency in short-term tests, but the fouling can be easily mitigated due to the hydrophilic surface. Conversely, a smooth surface initially reduces fouling, but leads to irreversible fouling due to the accumulation of foulants on the hydrophobic surface.

Summary: A novel CM-E-HOC process was proposed for the treatment of polymer-flooding produced water, achieving in situ self-cleaning and higher removal efficiency compared to the CM-EC process. The CM-E-HOC process showed improved coagulation performance due to the increased oxygen-containing functional groups and polymeric Fe species, resulting in better in situ self-cleaning performance and lower filtration resistance.

Summary: Electrodialysis is a rapid and reagentless method for stabilizing tartrate in wine. However, fouling of ion-exchange membranes by wine components remains a challenge. This study analyzed the effect of ethanol, polyphenols (mainly anthocyanins and proanthocyanidins), and saccharides (fructose) on the fouling of ion-exchange membranes. The results showed that fouling mechanisms and consequences differ in the absence of an electric field and during electrodialysis. A successful cleaning process was developed to prevent biofouling of ion-exchange membranes and enable selective recovery of high antioxidant activity polyphenols.

Summary: The study investigates the fouling tendency of positively charged, negatively charged, and non-charged surfactants on ion-exchange membranes. It is found that charged foulants in seawater could significantly foul the membranes, while the worst fouling behavior is observed when charged foulants are present in river streams. Through zeta potential measurement, it is demonstrated that the Debye length of charged foulants decreases in seawater streams due to higher ionic strength, leading to lower net electrostatic effect and less fouling tendency in reverse electrodialysis.

Summary: This work presents a versatile chemistry platform for the fabrication of hierarchical cation and anion exchange membranes (hCEMs and hAEMs) with tuneable transport properties. The hierarchical ion exchange membranes were made by coating and UV crosslinking an acrylic ionomer on top of a PVC-SiO2 porous substrate. The properties and performance of the membranes were found to be dependent on the coating crosslinking density, with higher crosslinking density resulting in better selectivity and performance.

Summary: This study investigates the effects of non-conductive pattern structures on ion transport through ion exchange membranes in electrodialysis (ED). The study identifies two factors, electric view factor and vortex intensity, that control conductive/convective ion transports. Experimental results on a two-dimensional ED platform show that these factors play a significant role in determining current, ion conduction, and salt removal performance.

Summary: A novel CO2-responsive copolymer was successfully synthesized and used in the fabrication of a blend membrane with switchable water flux. The protonation reaction of PDEAEMA segments within the membrane pores after CO2 aeration led to pore shrinkage and reduced water flux. By taking advantage of the CO2-stimulus responsiveness, a green cleaning method using alternate aeration was adopted to clean protein on the membrane surface, achieving a satisfactory flux recovery rate comparable to traditional cleaning methods.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.

Summary: A transmembrane electro-chemisorption system with authigenic acid and base was developed for enhancing ammonia recovery from strong ammonia wastewater. The system efficiently transformed ammonium into free ammonia, which was then adsorbed and recovered through transmembrane chemisorption. This system yielded pure (NH4)2SO4 product and produced valuable byproducts of pure hydrogen and oxygen. Higher applied voltage resulted in better ammonia recovery.

Summary: To meet the huge demand for lithium resources, there is an urgent need to develop a new efficient technology for lithium recovery from salt-lake brines. In this study, a selective membrane capacitive deionization system is reported, which achieves high lithium recovery capacity and rate through the use of materials with efficient intercalated pseudo-capacitance and a high specific area porous carbon. The use of a modified thin-coated membrane allows for selective Li+ recovery, and adjusting the concentrations of Li+ and Mg2+ in the feed solution enables higher Li+/Mg2+ selectivity.

Summary: In this study, a novel polydopamine-functionalized lignin-containing pulp foam evaporator with high-efficiency desalination and multi-contaminant adsorption capabilities was designed. The foam evaporator showed excellent light absorption, water absorption, thermal conductivity, and chelation abilities, allowing for solar evaporation and contaminant adsorption synergistically. It also exhibited potential applications in metal ion concentration and contaminated seawater treatments, and demonstrated superior biodegradability compared to poly-styrene foam. This foam material holds promise for developing multifunctional photo-thermal systems for solar-driven water purification.
