Summary: Industrial wastewater and produced water containing oil droplets must be processed properly to meet environmental standards before discharge, as it can pose a serious threat to marine life, the ecological environment, and human health. To address the challenge of oil-water separation, a superhydrophobic-superoleophilic surface with conical micro-arrays was developed to achieve ultrafast sorption of micro-oil droplets in water, providing a theoretical basis and technical support for fabricating underwater apparatuses for efficient oil droplet recovery from multiphase mixtures.

Summary: In this study, hedgehog-like micro/nanostructure nickel particles were successfully fabricated via a hydrothermal route and modified with octadecyltrichlorosilane (ODTS) to exhibit superhydrophobic/superoleophilic properties, making them suitable for oil/water separation. The dense narrow thorns of the nickel particles contribute to their high sorption capacity for various organic solvents and oils, and they also demonstrate good resistance. Moreover, the modified particles can be used for oil/water emulsion separation with high efficiency.

Summary: By using a simple two-step dipping method, an environmentally friendly and durable modified melamine sponge with superhydrophobic properties was fabricated. The sponge, named MS/rGO/AC/PDMS, has a multi-stage pore structure due to the fixation of active carbon and reduced graphene oxide on the melamine sponge skeleton with polydimethylsiloxane glue. The as-prepared sponge showed excellent water repellency with a water contact angle of up to 164 degrees. Used for oil/water separation, MS/rGO/AC/PDMS demonstrated outstanding oil-water selectivity, high oil sorption ability (up to 120 g/g), and separation efficiency over 99.85%.

Summary: SHSO membranes have shown high efficiency in selectively separating oil from oil-water mixtures, but their stability under acid and alkaline environments, as well as the adsorption of heavier components of crude oils, still require further research. Additionally, the fouling performance of SHSO membranes in water-derived fouling has not been well studied in oil-water separation applications.

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.
