“…The inactivation of indigenous bacteria (i.e., FC and ENT) by peracids in wastewater followed a biphasic behavior indicated by the different resistance to disinfection of the dispersed and particle-associated microbes. 39,45,46 An ICTbased double-exponential model was applied to predict the inactivation of FC and ENT in SEW (eq 5). 45,46…”

Performic acid (PFA) is an emerging disinfectant to inactivate bacterial and viral microorganisms in wastewater. In this study, the inactivation kinetics of murine norovirus (MNV) by PFA, in phosphate buffer and municipal secondary effluent wastewater, are reported for the first time. PFA decay followed first-order kinetics and the inactivation of MNV was governed by the exposure of microorganisms to PFA, i.e., the integral of the PFA concentration over time (integral CT or ICT). The extension of the Chick-Watson model, in the ICT domain, described well the reduction of MNV by PFA, with determined ICT-based inactivation rate constants, k d , of 1.024 ± 0.038 L/(mg•min) and 0.482 ± 0.022 L/(mg•min) in phosphate buffer and wastewater, respectively, at pH 7.2. Furthermore, the simultaneous PFA inactivation of MNV and fecal indicators indigenously present in wastewater such as fecal coliforms and enterococci showed that 1-log reduction could be achieved with ICT of 2, 1.5, and 3.5 mg•min/L, respectively. When compared with the most commonly used peracid disinfectant of municipal wastewater, peracetic acid (PAA), the ICT requirements determined using the fitted ICT-based kinetic models were ∼20 times higher for PAA than PFA, indicating a much stronger inactivation power of the PFA molecule.

“…Although WWTPs play an important role to remove or minimize a wide range of pollutants, they may act as the main entry pathways of ARGs and ARB into the environment (Kumar et al 2020). Besides, the chlorine-based disinfection in STWW could induce the discharge of ARGs from damaged microbial cells (Campo et al 2020). Based on the results, using STWW for agricultural irrigation might contribute to the spread of ARG and ARB to the environment.…”

“…In recent decades, the excessive use of antibiotics as therapeutic drugs in humans, animals, and plants caused selective pressure on bacterial populations, leading to the dissemination of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in the environment (Osinśka et al 2017;Yuan et al 2020). As a result, world health organization (WHO) established antibiotic resistance (AR) as a critical global health concern of the 21st century (Campo et al 2020;Yuan et al 2020).…”

“…ARB and ARGs are mainly spread by various environmental compartments such as wastewater treatment plant (WWTP) effluents (Osinśka et al 2017), surface water (Koczura et al 2012), livestock manure (Yuan et al 2020), and agricultural environment (Bougnom et al 2020). Wastewater as a nutrient-rich environment with a high microbial concentration and diversity provides favorite conditions for horizontal gene transfer (HGT) among bacteria (Osinśka et al 2017;Campo et al 2020).…”

Considering high concentrations of multidrug-resistant (MDR) bacteria and antibiotic resistance genes (ARGs) in wastewater, agricultural reuse of treated wastewater may be a public health threat due to ARGs dissemination in different environmental compartments, including soil and edible parts of crops. We investigated the presence of antibiotic-resistant Escherichia coli as an indicator bacterium from secondary treated wastewater (STWW), water- or wastewater-irrigated soil and crop samples. ARGs including blaCTX-m-32, blaOXA-23, tet-W, sul1, cml-A, erm-B, along with intI1 gene in E. coli isolates were detected via molecular methods. The most prevalent ARGs in 78 E. coli isolates were sul1 (42%), followed by blaCTX-m-32 (19%), and erm-B (17%). IntI1 as a class 1 integrons gene was detected in 46% of the isolates. Cml-A was detected in STWW isolates but no E. coli isolate from wastewater-irrigated soil and crop samples contain this gene. The results also showed no detection of E. coli in water-irrigated soil and crop samples. Statistical analysis showed a correlation between sul1 and cml-A with intI1. The results suggest that agricultural reuse of wastewater may contribute to the transmission of ARB to soil and crop. Further research is needed to determine the potential risk of ARB associated with the consumption of wastewater-irrigated crops.

“…However, to date, not many studies have reported the disinfection effect of PAA and PFA on ARB and ARGs 70)-72) . Campo et al (2020) 71) reported the inactivation effect of PAA and PFA on ampicillin-resistant E. coli in secondary treated water. In this study, PAA was able to inactivate ampicillin-resistant E. coli to below the detection limit at a CT value of ~55 mg・min/L (inactivation ratio > 5 log).…”

Antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs) are an emerging contaminant of concern. However, the present sewage treatment plants (STPs) are not designed with treatment units for direct removal of ARB and ARGs. STPs are considered to be hotspots of horizontal gene transfer of ARGs as well as a major source of their emissions in the aquatic environments. In order to mitigate the risk of infection by ARB and ARGs, their reduction in STPs needs to be fully understood. This review focused on disinfection, the tertiary treatment of the sewage treatment process, and discussed the advantages, limitations, and improvements in the process using each disinfection technology, with the aim of identifying treatment strategies and further research directions for future ARB and ARGs in reducing emissions into the environment.
