Summary: The efficacy of disinfection processes in water treatment plants in preventing the spread of viruses during the COVID-19 outbreak is unclear. This study analyzed the effects of different disinfection processes, such as UV and chlorine, on waterborne viruses using bacteriophage surrogates. The results showed that sequential UV-chlorine disinfection had a synergistic effect on virus inactivation, and UV irradiation enhanced the sensitivity of viruses to subsequent chlorination.

Summary: The inactivation kinetics of coxsackievirus serotype B5 (CVB5) by free chlorine was studied to select experimental conditions for determining inactivation mechanisms. Our findings suggest that the inactivation kinetics of CVB5 by free chlorine is conservative and comparable to published experimental data, which can be useful in developing disinfection treatments and regulations for waterborne viral pathogens, including CVB5. The effect of free chlorine exposure on viral genome integrity, attachment to host cell, and viral genome replication was quantitatively investigated using a reverse transcription-quantitative polymerase chain reaction (RT-qPCR) method. The observed inactivation kinetics is attributed to hindered virus attachment, inhibition of replication steps, and potential genome damage.

Summary: This study characterized Bacillus globigii as a suitable surrogate for wastewater treatment-related studies, demonstrating that it is more effective in UV inactivation and PAC adsorption compared to Bacillus anthracis Sterne. However, there was no significant difference in bioaerosol emission between the two. These findings provide important insights into the use of Bacillus globigii as a surrogate for Bacillus anthracis Sterne in bioaerosol emissions.

Summary: The study evaluated the efficacy of a novel photochemical method for generating chlorine dioxide against human noroviruses surrogate, bacteriophage MS2, and Clostridium difficile endospores, showing promising results in controlling viral and bacterial pathogens. Further optimization and testing against environmentally resilient pathogens are needed.

Summary: The performance of the UV365/chlorine process on bacterial inactivation was comprehensively investigated in this study, showing better performance than UV365 alone and chlorine alone processes. This better performance can be attributed to the reactive species generated in the UV365/chlorine process. Inactivation of E. coli, S. aureus, and B. subtilis was confirmed through various evaluations, and the order of bacterial inactivation was found. Additionally, the combined UV365/chlorine process showed the lowest reactivation potential and fewer disinfection byproducts compared to direct chlorination.

Summary: Bacteriophage and gaseous ozone are effective in reducing Escherichia coli O157:H7 in fresh produce when used in sequential treatments. The combination of phage and ozone, applied with vacuum cooling, can significantly decrease the pathogen population on spinach leaves. Regardless of the application order, E. coli O157:H7 populations were reduced below the detection level.

Summary: The application of chemical disinfectants in postharvest food processing facilities is crucial for controlling foodborne pathogen outbreaks. This review focuses on the use of chlorine and ozone as disinfectants in food washing facilities, highlighting the differences in conditions compared to drinking water disinfection. The research emphasizes the challenges of pathogen inactivation on food surfaces and the effectiveness of these disinfectants in preventing pathogen cross-contamination through washwater.

Summary: The virucidal efficacies of disinfectants vary depending on the host cell used in the infectivity assay. Different host cells may have different entry routes for enteroviruses, and the choice of host cell can affect the observed inactivation kinetics of the disinfectant. The inactivation rates of echovirus 11 by UV or heat were independent of the host cell, but the inactivation by free chlorine was faster when enumerated on BGMK cells compared to RD and A549 cells. This host cell-dependent inactivation kinetics were also observed for other enteroviruses.

Summary: The study examined the inactivation kinetics of different enterovirus variants by free chlorine and UV irradiation, revealing that the inactivation mechanisms of free chlorine are genotype- and genogroup-dependent, while UV inactivation mainly depends on genomic size and composition. The distribution of inactivation rate constants and the abundance of each genotype are crucial parameters in accurately predicting the overall inactivation of an enterovirus population by free chlorine.

Summary: This study investigates the effect of zero-valent iron nanoparticles (nZVI) on different bacteriophages and suggests that nZVI can be an environmentally friendly, inexpensive, and efficient method of phage inactivation. The reduction of plaque-forming units varied depending on the bacteriophages, and the importance of oxidation of nZVI versus the release of Fe2+/Fe3+ ions is discussed. The proposed mechanism of action involves redox reactions, virion adsorption, and the impact of released iron ions.

Summary: This study investigated the roles of diverse free available chlorine (FAC) species including HOCl/OCl-, H2OCl+, Cl2O, and Cl-2 in the degradation of micropollutants. The reaction orders in FAC (n) of 5 micropollutants ranged from 1.4 +/- 0.2 to 2.1 +/- 0.3 at pH 3-5, demonstrating the importance of Cl2O and Cl-2. A simplified method for determining the rate constants (k) of specific FAC species with micropollutants was developed. Cl-2 and Cl2O played vital roles in both micropollutant degradation and disinfection byproduct (DBP) formation during chlorination.

Summary: This study compared the inactivation efficiency of E.coli by single ozone, single chlorine, and sequential ozone-chlorine disinfection approaches. It was found that sequential ozone-chlorine disinfection could completely inactivate microorganisms and improve the efficiency of chlorination. By establishing a model to estimate the inactivation rate, the study provided informative insights for optimizing the disinfection units of WRPs.

Summary: This study aimed to investigate the effect of water activity on the inactivation of Listeria monocytogenes using gaseous chlorine dioxide. The results showed that the antimicrobial effect of chlorine dioxide decreases as water activity levels and chlorine dioxide concentrations decrease. The modified Chick model was found to be more suitable for describing the inactivation of L. monocytogenes and could be used to design treatment processes for inactivating L. monocytogenes in low-moisture foods.
