Summary: Photocatalytic inactivation of pathogens in aqueous waste is a topic of increasing interest. This study compares the effectiveness of homogeneous and heterogeneous photocatalysis using Fe+3 and TiO2, respectively, for inactivating various microorganisms. It is found that homogeneous photocatalysis achieves more efficient microorganism inactivation in a shorter processing time compared to heterogeneous photocatalysis. Additional optimization of TiO2 photocatalysis with H2O2 supplementation further enhances the inactivation efficiency.

Summary: The study found that different-sized biosand filters showed varying effectiveness in removing bacteria, protozoa, and viruses, with the addition of iron nails significantly improving bacteria and protozoan removal. Both pause period and filter type influenced virus removal, with scaled-down biosand filters providing a viable household water treatment option for those still lacking access to improved water sources.

Summary: Despite the widespread adoption of wastewater surveillance, more research is needed to understand the fate and transport of viral genetic markers in wastewater. In this study, the solid-liquid partitioning behavior of four viruses in wastewater was examined using laboratory experiments and endogenous viruses in raw wastewater. The results showed that the RNA concentrations of the viruses were higher in the solid fraction than the liquid fraction by approximately 3-4 orders of magnitude. Further research is needed to understand how virus and wastewater characteristics might influence the partitioning of viral genetic markers in wastewater.

Summary: In this study, a citrate-modified photo-Fenton process was successfully used to decontaminate a Chlorella vulgaris microalgae culture contaminated with the rotifer Brachionus calyciflorus. The treatment had moderate effects on microalgae viability and regrowth, and effectively eliminated the rotifers. Comparison with a solar light/H2O2 treatment showed that the citrate-modified photo-Fenton treatment had a lower negative impact on microalgae regrowth. However, full elimination of rotifers requires early-stage application of the photo-Fenton process.

Summary: This study compared the effectiveness of three advanced oxidation processes, Fenton, UV/Fenton, and UV/H2O2, for treating wastewater containing various components commonly found in semiconductor wastewater. The UV/Fenton process at an initial pH of 8.3 showed the best overall removal rate due to synergistic effects of various factors. The presence of co-contaminants in actual semiconductor industrial wastewater impacted the removal rates of pyrazole and DGA differently for each AOP.

Summary: Increasing global concern over hazardous pollutants in water bodies due to their toxicity and threat to the environment has led to the need for new or upgraded remediation methods. Advanced oxidation processes (AOPs) utilizing highly reactive oxidizing radicals like center dot O and center dot OH have shown efficacy in the mineralization of dye pollutants. Sonolysis, a newer AOP that employs ultrasound irradiation for generating oxidizing radicals, has become a robust hybrid AOP for degrading environmental contaminants. This review focuses on the degradation of dyes through ultrasound-based AOPs and discusses different sono-based methods and their efficacy for wastewater treatment.

Summary: This manuscript explores the improvement of solar disinfection (SODIS) for water treatment by utilizing iron replacements, such as calcined herbs and spices, in the photo-Fenton reaction. The study evaluates the bactericidal performance of SODIS, H2O2/light, and solar photo-Fenton in both pure and Lake Leman water. The findings demonstrate that the addition of certain spices/herbs enhances the H2O2/light process, while the use of ashes as substitutes for Fe2+ results in faster kinetics.

Summary: This study investigates the effect of surface modifiers on the catalytic properties and degradation efficiency of a polymeric matrix (CuO/PVA) using three different surfactants: cationic (CTAB), anionic (SLS), and non-ionic (T80). The results show that surface modification significantly enhances the degradation ability of the polymeric CuO, with CTAB-assisted CuO exhibiting a 29% higher degradation rate compared to its unmodified counterpart. The surface characteristics of the catalyst, including particle size, band gap, and morphology, also play a crucial role in the degradation process.

Summary: In this study, a ternary ZnO@spinel cobalt ferrite@carbon nanotube magnetic photocatalyst (ZSCF@CNT) was synthesized and used for Cefixime (CFX) antibiotic degradation under UVC irradiation. The ZSCF@CNT photocatalyst showed superior catalytic activity compared to individual components and binary composite catalysts, rapidly removing CFX under UVC irradiation and PMS. The optimal conditions for catalytic activity were pH 7.0, catalyst concentration 0.3 g/L, and PMS concentration 3.0 mM, resulting in complete elimination of CFX (10 mg/L) in about 20 minutes.

Summary: An innovative photoreactor, consisting of luminous fiber textile coupled to UVA LED and photocatalytic textile fibers impregnated with TiO2, was used to investigate the degradation of Paracetamol (PL) under different operating conditions. Configuration I showed a 40 times higher degradation rate and 81 times higher mineralization per Watt consumed compared to configuration II. The optimal conditions for a 95.7% degradation rate of 1 mg/L Paracetamol were achieved with 26 g/m2 mass catalyst, 5 W/m2 UV intensity, and 52.2 L/h flow rate after 340 min. Addition of hydrogen peroxide (H2O2) further increased the degradation efficiency.
