Summary: Azo dyes, widely used in textile industries, are difficult to degrade due to their xenobiotic nature. However, recent studies have shown that many microorganisms can convert these toxic azo dyes to non-colored compounds or even mineralize them under specific environmental conditions. This study evaluated the decolorizing efficiency of newly isolated Paramecium species in textile industrial wastewater containing azo dyes. The results showed that Paramecium species had a high decolorization rate under optimum conditions, making them potentially useful for bioremediation of textile-dying industry effluents.

Summary: This study evaluated a new combined treatment approach by combining ozonation and electrolysis for the mineralization of organic compounds in water. The results showed that the method was most effective for TOC removal in alkaline conditions and significantly enhanced performance compared to ozonation alone in acidic conditions. The initial pH had a more significant effect on TOC removal than current density, but both parameters were relevant. Under optimized conditions, 63% TOC removal was achieved.

Summary: Reduced graphite oxide (rGO) materials have shown great potential in advanced oxidation processes for the catalytic degradation of organic pollutants in water. The application of rGO as a metal-free catalyst in the Fenton reaction depends on its degree of reduction. This study prepared rGO using the modified Hummers' method and two-step reduction via hydrothermal and calcination processes. The effectiveness of as-prepared rGO as a photocatalyst and metal-free catalyst for decolorization of various textile dyes was investigated, and factors such as catalyst dose, pH, and initial dye concentration were examined. The recyclability of rGO in the photocatalytic system was also examined.

Summary: In this study, metakaolin-based geopolymer was obtained by activating metakaolin with an alkali activator containing silica fume and sodium hydroxide. The addition of silica fume and adjustment of Na2O/Al2O3 molar ratio resulted in the formation of geopolymer-zeolite composites, which exhibited higher compressive strength. The presence of large zeolite crystals in the geopolymer matrix was observed in the composite with 10 wt% silica fume and a Na2O/Al2O3 molar ratio of 1. The maximum compressive strength was achieved at 15 wt% silica fume, Na2O/Al2O3 molar ratio of 1, and curing temperature of 70 degrees C.

Summary: MIL-53(Fe) was synthesized as a three-dimensional metal-organic framework with different precursors-to-solvent ratios, denoted as MIL53B and MIL53C. Modified versions, MIL53B/NH2 and MIL53C/NH2, with varying NH2 ratios (0.10, 0.20, and 0.30), were also prepared using organosilane. The materials were characterized using XRD, SEM, EDS, and FTIR techniques, and their adsorption capacity for dye (Direct Red 23) was studied. The modified MIL53 showed higher adsorption capacity (4,989 mg/g) compared to the unmodified version (1,375 mg/g), indicating its potential as a dye adsorbent and for removing similar organic molecules from contaminated water.

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.
