Summary: The study found that ozonation led to a dose-dependent increase in biological activity, particularly for substances that are recalcitrant to biodegradation. Additionally, ozonation enhanced the degradation potential of COD and BDOC, while also partially mineralizing organic compounds. These results suggest that a combination of ozonation and biological post-treatment can contribute to sustainable water resource management by reducing biodegradable organic carbon emissions.

Summary: The VUV/UV process effectively removes organic fluorine compounds from fluoride-containing pharmaceutical wastewater, with degradation mainly attributed to the attack of the fluorine atom by HO· generated from VUV photolysis. The removal efficiency of COD and the release ratio of F- in real pharmaceutical wastewater vary significantly under different pH and dissolved oxygen saturation conditions. The biodegradability index of pharmaceutical wastewater is significantly improved after VUV/UV treatment.

Summary: A dimensionless artificial neural network (ANN) is developed to simulate the remediation of organic waste-polluted muds. The mud is pretreated with synthetic seawater and anionic surfactant, and oxidized with ozone-rich gas in a semi-batch bubble flow column. Experimental data are used to calibrate a knowledge-based model (KBM) for generating simulated results to be used for ANN. The interpretation of ANN results shows that the removal efficiency of total organic carbon (TOC) is enhanced by increasing the initial TOC concentration in the solid phase, pre-treating mud with seawater/surfactant solution, increasing ozone concentration of injected gas, having moderate Reynolds number in the liquid phase, and high SDS concentration.

Summary: The presence of salts, particularly chloride ions, significantly influences the performance of both conventional and catalytic ozonation processes by affecting the rate and extent of organic compound degradation. This influence is due to scavenging of O-3, transformation of organics to more hydrophobic forms, and inhibition of hydroxyl radicals. Through appropriate choice of catalyst, this effect can be mitigated to some extent.

Summary: Catalytic ozonation is a technique that uses active free radicals generated by ozone degradation to mineralize organic matter in water. It can be divided into homogeneous catalytic reactions using metal ions as catalysts and heterogeneous catalytic reactions using solid catalysts. Heterogeneous catalytic ozonation has advantages such as easy recovery, lower cost, higher activity, and improved mineralization rate compared to homogeneous catalytic ozonation.

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: This study evaluates the methane production potential of pig slurry anaerobic digestion using two different substrate to inoculum ratios (SIR 0.65 and 1) and compares it with theoretical predictions. The results show that a higher SIR of 1 produced more biogas with higher methane content compared to a lower SIR of 0.65, with an SMP of 0.568 NL CH4/g VS and an average methane content of 83% achieved in the experiment. The estimated value presented a deviation of just 2.96% during the assay with a SIR of 1.

Summary: Agro-industrial wastewater management is becoming increasingly important as environmental regulations become stricter worldwide. These wastewaters are known for high organic pollutant content, which adversely affects water bodies. Industries are seeking efficient, user-friendly, and affordable treatment processes. Sulfate radical based advanced oxidation processes (S-AOPs) are emerging as suitable alternatives for treating agro-industrial effluents. This review discusses the major findings regarding the application of this technology for real agro-industrial wastewater treatment, comparing it with Fenton's process, which is widely studied and highly efficient in treating agro-industrial effluents. Promising results have been achieved in existing studies, but there is still a lack of research in this area and using this technique.

Summary: Ensuring drinking water quality is crucial for public health, especially in the context of increasing industrialization. Disinfection is a key process, but it leads to the formation of unwanted disinfection byproducts (DBPs) that negatively impact human health. Stricter regulations and techniques for DBP removal have been developed, but further research is needed to monitor and control these contaminants in water distribution systems.

Summary: The increasing demand for fresh water requires industries to reduce the need for it, especially in the winemaking industry, which has a significant impact on water resources due to high water consumption and wastewater production. The sun-driven photooxidation process is widely used for wastewater treatment, and this study employed four photosensitizers to remove pollutants from wastewater for water reuse. Among the photosensitizers used, ZnPcS4 showed better removal of chemical oxygen demand (COD) and phenolic compounds (TPH). The study also evaluated the effect of pH and concentration on ZnPcS4, finding that alkaline solutions improved the removal efficiency but also caused bleaching of the photosensitizer.

Summary: Graphitic carbon nitride (g-C3N4) catalysts were synthesized using melamine, urea, and thiourea as precursors, and their influence on photocatalytic performance was investigated. Urea-based catalyst (UCN) showed the best results under all radiation sources, followed by thiourea and melamine. UCN achieved higher degradation of parabens under UVA compared to visible light, while natural sunlight had the highest removals using UCN. UVA lamps consumed 45% less energy and costs. Photocatalytic ozonation using UCN and MCN showed superior performance and complete removal under 12 minutes.

Summary: In this study, the optimization of heterogeneous photosensitized oxidation treatment of winery effluents using chitosan carriers immobilized with Zn(II) Phthalocyanine tetrasulfonic acid was investigated. The effects of initial pH, aeration flow rate, photocatalyst load, and photosensitizer concentration on the treatment process were studied. The best reductions in COD and phenolic content (TPh) were achieved after 30 min of treatment in natural sunlight at an initial pH of 4.0 and an aeration flow rate of 2.8 L/min, with COD reduction of 45% and TPh reduction of 73%. The possibility of reusing the photocatalysts was also evaluated, and it was found that acidic pH allowed for their reuse without leaching of the photosensitizer.

Summary: Developing highly efficient bifunctional oxygen electrocatalysts is crucial for zinc-air flow batteries. Metal-organic frameworks (MOFs) and covalent organic polymers (COPs) have emerged as promising alternatives due to their designable and controllable atomic-level structures. However, their catalytic performances are limited by conductivity and catalytic activity. In this study, nanosheet FeNi-MOF and iron phthalocyanine rich COP hybrid materials are assembled through the pi-pi stacking effect to create highly efficient bifunctional electrocatalysts. The resulting catalyst exhibits superior catalytic performance and stability, making it a promising candidate for zinc-air flow batteries.
