Summary: This study reports a simple and highly efficient air spraying strategy to fabricate an omniphobic membrane by spraying a coating solution comprising fluorinated multi-walled carbon nanotubes (F-MWCNTs) onto a commercial polytetrafluoroethylene (PTFE) membrane. The contact angles for water and hexadecane on the surface reached 173.0 degrees and 161.2 degrees, and the water flux remained stable for 12 h when tested in DCMD with low surface tension fluids (SDS and STAC). The omniphobic membrane showed higher wetting resistance in direct membrane distillation (DCMD) experiments than the PTFE membrane when feeding low surface tension feed solutions.

Summary: A fluorine coating material was used to enhance membrane performance in the membrane distillation process. The coating process was simple and quick, without altering the membrane's morphology or chemistry. The coated membrane had the same pore structure but significantly reduced surface free energy, which provided excellent anti-wetting and anti-scaling properties. In various tests, including surfactant and scaling agent presence, the coated membrane outperformed the pristine membrane. Additionally, it showed promising results in water recovery tests from synthetic seawater, highlighting its practical applications.

Summary: This study demonstrates the potential of photothermal membrane distillation (PMD) in addressing the water-energy nexus. The authors developed a microsphere structured composite membrane with superior light-to-heat conversion and superhydrophobic properties. The membrane showed high light absorptivity, heat recovery, and vapor production, along with excellent wetting resistance. The localized heating alleviated temperature polarization, increased the permeation flux, and reduced thermal energy consumption. The modified membrane also exhibited better anti-scaling properties compared to the original membrane.

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.
