Summary: The study investigated the toxicity and transformation characteristics of triclosan ozonation and chlorination, revealing the generation of toxic chlorinated compounds during chlorination and the mitigation of genotoxicity with ozonation treatment. Chlorination led to a 30-fold increase in anti-estrogenic activity, while ozonation could reduce the toxicity of triclosan-containing water. Therefore, ozonation may be a more environmentally friendly and safe method for treating triclosan wastewater.

Summary: Pharmaceutical and personal care products (PPCPs) are widely consumed and often end up in water bodies due to inefficient conventional wastewater treatments. To tackle these stubborn contaminants, advanced oxidation processes like photocatalysis and ozonation have been studied. This research evaluated the effects of different N and Ce loads in co-doping TiO2 catalysts on the efficiency of photocatalytic oxidation and photocatalytic ozonation for PPCPs abatement, as well as their toxicity to aquatic species. The study found that photocatalysis had low efficiency on PPCPs removal (<20%), while photocatalytic ozonation achieved up to 100% removal, with lower ozone dose. A specific catalyst, doped with 2.5% w/w N and 1.2% w/w Ce, showed promising results for photocatalytic ozonation. Therefore, N and Ce co-doped TiO2-based catalysts have potential in wastewater treatment using photocatalytic ozonation.

Summary: The investigations on the removal of ibuprofen in a hybrid system coupling ozonation and nanofiltration with functionalized catalytic ceramic membrane are presented. Positive influence of catalytic ozonation on ibuprofen decomposition was observed. The application of catalytic nanofiltration membrane led to a higher ibuprofen removal rate compared to the pristine membrane, and the addition of inorganic salts did not affect the removal efficiency. Three IBU by-products were detected during the treatment process, but after 2 hours of catalytic nanofiltration, the treated product was found to be non-toxic.

Summary: In this study, the feasibility of low-cost catalysts (gamma-Al2O3, spent FCC catalyst, and natural zeolite) in the pyrolysis of wood-plastic composite (WPC) was evaluated using thermogravimetric and pyrolyzer-gas chromatography/mass spectrometry analyses. The use of low-cost catalysts during catalytic fast pyrolysis (CFP) was found to decrease the decomposition temperature of polyethylene and polypropylene in WPC. Natural zeolite exhibited the lowest activation energy (Ea) of CFP, followed by spent FCC catalyst and gamma-Al2O3, respectively. Although CFP over natural zeolite was less effective in decreasing the production of low-quality hydrocarbons, paraffins, and olefins compared to spent FCC catalyst and gamma-Al2O3, it produced the largest amount of value-added aromatic hydrocarbons due to its high and strong acidity.

Summary: This study investigated the catalytic ozonation of different Cl-VOCs over supported MnOx catalysts and found that the catalytic performance and byproducts formation varied among different Cl-VOCs. Among all the Cl-VOCs, Mn/HZSM-5(27) showed better conversion and mineralization rate, and the catalytic co-ozonation of mixed Cl-VOCs exhibited both inhibitive and promotive effects. Competitive adsorption and the difficulty of Cl-VOCs degradation were the determining factors in catalytic co-ozonation, while the presence of H2O had negligible impact. These findings provide valuable references for industrial applications involving multiple Cl-VOCs and water vapor.

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: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
