Summary: This research investigated the removal of boron and arsenic from geothermal water using newly synthesized gel-like chelating resins. The results showed that the novel resins were able to reduce boron and arsenic concentrations in geothermal water below permissible levels for agricultural irrigation and drinking water. The optimal resin concentration for boron removal was determined to be 2 g/L, while for arsenic removal, a resin concentration of 8 g/L was needed for 94% removal using the novel resins compared to 32 g/L for commercially available resin. Column performance characteristics of the resins were also studied and compared to a commercially available resin.

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.

The effect of temperature on water permeate flux, specific energy, permeate quality, and applied operating pressures is evaluated using an analytical model. The results suggest that under specific conditions, the tradeoff between savings in mechanical pump work and thermal energy input in thermally-enhanced RO can be favorable, leading to overall energy savings.

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.
