Summary: This study reveals the potential risk of generating disinfection byproducts (DBPs) when treating iodine-containing wastewater with peracetic acid (PAA), especially under acidic conditions. The reaction rate is higher under acidic conditions, resulting in more iodinated aromatic products and higher toxicity towards bacteria. Under alkaline conditions, more adsorbable organic iodine (AOI) is generated.

Summary: This study incorporated microwave-enabled catalysis into membrane filtration and evaluated viral removal using a model bacteriophage (MS2) as a surrogate. The findings showed that microwave irradiation effectively penetrated the PTFE membrane module and enabled surface oxidation reactions on the membrane-coated catalysts, resulting in strong germicidal effects. A log removal of 2.6 was achieved for MS2 within a contact time as low as 20 s using 125-W microwave irradiation. This research provides new insights to the antiviral mechanisms of this microwave-enabled catalytic membrane filtration.

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: This review comprehensively analyzes the PAA-based disinfection processes in wastewater treatment, including its advantages, efficacy, disinfection mechanisms, and its interactions with conventional disinfection processes. The review also discusses the risk of pathogen regrowth and the impact of PAA on the spread of antibiotic-resistant bacteria and antibiotic resistance gene transfer.

Summary: The study found that PAA effectively inactivates viruses by targeting susceptible amino acids on capsid proteins, while having little impact on viral genomes. Viruses with higher total number of target amino acids in their capsid structures may be more susceptible to PAA reactions.

Summary: Pemialeic acid (PMA) was investigated as a potential disinfecting agent and compared to peracetic acid (PAA) in tap water and wastewater. The study found that the disinfection efficiency of PMA is strongly influenced by the water quality, concentration of bivalent ions, and initial pH.

Summary: The study found that UV/PAA-H disinfection was most effective for removing tetracyclines, quinolones, macrolides, and beta-lactams, while NaClO disinfection was effective for removing sulfonamides. The majority of ARGs were well removed after UV/PAA-H disinfection, but specific genes increased after NaClO disinfection. The highly reactive oxidation species generated from the UV/PAA process were responsible for the elimination of antibiotics and ARGs.

Summary: This review provides a comprehensive analysis of scientific information and experimental data on the applications of PAA-based AOPs for the removal of chemical and microbiological micropollutants from water and wastewater. Various methods of PAA activation and degradation mechanisms are discussed, along with the application of PAA for water disinfection and related mechanisms of microorganism inactivation. The review also focuses on the advantages and disadvantages of UV/PAA as an AOP compared to UV/H2O2, highlighting knowledge gaps, challenges, and new opportunities for research in this field.

Summary: The study investigated the inactivation kinetics of multidrug-resistant bacteria in wastewater by the emerging environmentally-friendly disinfectant peracetic acid (PAA), showing that the inactivation was governed by exposure time and concentration integral. Soluble constituents in wastewater decreased PAA inactivation effectiveness, and chlorine showed higher inactivation of resistant bacteria compared to PAA.
