Summary: This study investigates the concept of using heat to enhance reverse osmosis (RO) desalination. 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: The fouling of seawater reverse osmosis membranes is a persistent challenge in desalination. This study monitored the operational performance of a desalination plant for 7 years and the fouling development in different areas of membrane modules. The findings showed that operational performance declined over time and fouling mainly occurred at the feed side of the modules, with the highest microbial diversity. Keystone species like Chloroflexi and Planctomycetes played an important role in maintaining community structure and biofilm maturation. Polysaccharides, soluble microbial products, marine humic acid-like substances, and inorganic substances contributed to fouling. Overall, biofouling had a significant impact on membrane fouling after 7 years of operation.

Summary: This study investigates the potential of cation-intercalated graphene oxide (GO) membranes for boron removal via molecular dynamics simulations. The study reveals that GO membranes effectively reject borate ions due to electrostatic repulsion, with K+ ion intercalated GO membranes showing higher rejection than Mg2+ ion intercalated GO membranes. The presence of oxygen-containing functional groups on the GO membrane affects boron rejection. Furthermore, Mg2+ ion intercalated GO membranes exhibit higher water permeance, excellent Na+ rejection, and poor Cl- rejection compared to K+ ion intercalated GO membranes.

Summary: Chiral separation membranes have great potential for separating racemic mixtures into enantiopure components, but fabricating scalable membranes with both high selectivity and flux is challenging. In this study, a new type of enantioselective membrane was prepared using enantiopure S-poly(2,4-dimethyl-2-oxazoline) macromonomers and supported by graphene oxide nanosheets. The S-PdMeOx-based membrane showed near-quantitative enantiomeric excess and a high flux. This work demonstrates the potential of homochiral polymers in chiral discrimination and provides a new route to develop highly efficient enantioselective membranes.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
