Summary: Hydrodynamic cavitation (HC) was used to activate sodium percarbonate (SPC) and ozone (O3) for the degradation of recalcitrant 1,4-dioxane. Under optimal conditions, the degradation efficiency was > 99% in 120 minutes. The presence of SPC increased the degradation efficiency and HC/SPC/O-3 was more effective than HC/H2O2/O-3, indicating a synergistic effect.

Summary: In the past two decades, the detection of pharmaceuticals in water bodies has become a concern due to advancements in detection technologies. Pharmaceuticals can have toxic effects on both human and animal life when present in environmental waters. Advanced oxidation processes (AOPs) have been found to effectively target pharmaceutical compounds using powerful oxidizing radicals. However, there are drawbacks associated with AOPs, such as the generation of chemical sludge and high energy requirements. This review discusses different chemical treatment technologies for removing pharmaceuticals and emphasizes the combination of AOPs for increased removal and mineralization efficiency.

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 analyzes the application of wet oxidation and ozonation in the removal of microplastics from wastewater. It was found that wet oxidation can remove approximately 86.3% of microplastics, while ozonation can remove approximately 45.2% of microplastics. Further experiments showed that ozonation mainly removes microplastics through gas bubbling, while wet oxidation mainly removes microplastics through chemical degradation. Finally, it was also found that the removal of microplastics is accompanied by fragmentation.

Summary: Paracetamol (PCT), a widely prescribed drug, is not completely absorbed by animals and humans, leading to its contamination of aquatic environments through urine. Trace amounts of PCT have been found in various water sources. PCT has toxic effects on different organisms and ozonation methods have been proposed as effective treatments for its removal. This comprehensive review focuses on the application of ozonation processes, including direct ozonation and hybrid catalytic ozonation, for PCT removal from natural waters, synthetic waters, and real wastewaters. The review discusses the fundamentals, operating variables, best results, and mineralization performance of these ozonation methods.

Summary: The use of nanofluids in enhanced oil recovery processes has gained attention due to the possibility to increase oil recovery from mature oil fields. Silica nanoparticles are widely used for nanofluid formulations, but there are obstacles such as stability, environmental and economic aspects, and the need for suitable large-scale production processes. This study evaluates oil recovery using silica-based nanofluids from different sources under various operational conditions, and demonstrates that silica from rice husk ash has comparable efficiency to other synthetic silica nanoparticles.

Summary: Urbanization and industrialization have negatively impacted water quality, leading to a demand for reliable and eco-friendly treatment technologies. Persulfate-based advanced oxidation processes (AOPs) have shown promise in treating challenging industrial wastewaters and remediating contaminated groundwater. Comparisons of reaction rate constants for different pathways suggest that radical-based AOPs can achieve high removal efficiency with short contact times, while nonradical AOPs are advantageous for complex wastewater treatments with minimal interference. However, nonradical pathways require significantly higher energy requirements. These comparisons inform the prioritization of basic research and the understanding of system-specific application merits and limitations.
