Summary: This study evaluated the alleviation of membrane fouling for the treatment of shale gas produced water (SGPW) using sodium percarbonate oxidation and aluminum sulfate coagulation. The results showed that the combination of oxidation and coagulation effectively reduced turbidity, UV254, and DOC, as well as fluorescent organics in the SGPW samples. The normalized fluxes were significantly improved compared to the raw SGPW, indicating the potential of this combined pretreatment process in controlling membrane fouling.

Summary: The acid precipitation treatment of black liquor results in two main streams: high purity precipitated lignin and lignin-lean black liquor. This study evaluated the ultrafiltration process for recovering lignin from lignin-lean black liquor at different pH values, showing that the process retained 83% of lignin at pH 9.0. The permeate flux increased with decreasing pH, and ultrafiltration led to a decrease in the weight average molecular weight of lignin-lean black liquor. Additionally, permeate samples exhibited different chemical properties compared to feed samples.

Summary: Heterogenous photocatalysis with silver-decorated titanium dioxide (TiO2) catalysts supported on alumina hollow fibers showed potential for efficient Cr(VI) photoreduction in wastewater treatment. The addition of ultrasound during the synthesis process improved the distribution of Ag nanoparticles on the TiO2 surface. Higher loading of Ag nanoparticles (30 wt%) led to significant enhancement in Cr(VI) photoreduction activity of the TiO2 catalyst. Both suspended and internally or externally supported catalysts achieved complete Cr(VI) photoreduction after prolonged reaction times. However, the externally supported catalyst exhibited superior activity, especially in the initial reuse cycles.

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.
