“…The information above on the main techniques applied for wastewater disinfection underlines the need to identify the most suitable processes to treat sewage. In fact, the contamination of surface waters by pathogenic microorganisms, as a consequence of inadequate wastewater disinfection, may promote waterborne disease spread, including those caused by pathogenic Campylobacter, Shiga toxin (Stx)-producing Escherichia coli (STEC) and Salmonella [15][16][17]. Although the predominant mode of Campylobacter and STEC transmission to humans is via the consumption of contaminated foods, water can also be a source of human exposure [18,19].…”

One source of water contamination is the release of wastewater that has not undergone efficient treatment. The aim of this study was to evaluate the reduction obtained with sodium hypochlorite (NaClO), UV and peracetic acid disinfection treatment of Salmonella spp., pathogenic Campylobacter, STEC and bacterial indicators in three full-scale municipal wastewater plants. A general reduction in Salmonella was observed after disinfection, but these bacteria were detected in one UV-treated sample (culture method) and in 33%, 50% and 17% of samples collected after NaClO, UV and PAA disinfection treatments, respectively (PCR method). A better reduction was also observed under NaClO disinfection for the microbial indicators. Independent of the disinfection treatment, E. coli O157:H7 was not detected in the disinfected samples, whereas some samples treated with UV and PAA showed the presence of the stx1 gene. No reduction in the presence of stx2 genes was verified for any of the disinfection treatments. Campylobacter was not detected in any of the analysed samples. The overall results highlight a better reduction in microbiological parameters with a NaClO disinfection treatment in a full-scale municipal wastewater plant compared with UV and PAA. However, the results indicate that a complete and specific monitoring program is necessary to prevent a possible risk to public health.

Developed control of chemical disinfection techniques is beginning to be progressively significant in order to equilibrate under-treatment (minimal pathogen demobilization) and over-treatment (immoderate consumption of disinfectant and disinfection by-products generation) that way giving great ecological and economic advantages. This work reviews the most recent and pertinent researches in this field of eliminating Antibiotic-resistant Bacteria (ARB) carrying genes (ARGs) during wastewater treatment especially disinfection. Traditional disinfection techniques may not be efficient in demobilizing ARB and the simultaneous liberation of ARB and antibiotics at sub-lethal concentrations into municipal wastewater treatment plant effluent may promote the development of resistance among bacteria in receiving water. The pathway of the influences of diverse disinfection techniques in water and wastewater (chlorination, UV irradiation, Fenton reaction, ozonation, and photocatalytic oxidation) deserves more attention. The impacts of constructed wetlands and nanotechnology on ARB and ARG have to be more explored. As the best available technology, membranes processes should be widely adopted through the world for removing ARB and ARGs from the perspective of reusing treated wastewater as drinking water. These safe barriers against pollutants diffusion in nature merit more technical and economic expansion for their larger industrial application especially in developing countries.

“…PAA has a high disinfection efficiency and less formation of harmful disinfection byproducts (DBPs) compared to those chlorine-based disinfectants [22]. Thus, it is recommended as an attractive disinfectant for secondary and tertiary wastewater effluents in many countries, (e.g., Canada and parts of Europe) [23][24][25]. In fact, the PAA solution is an equilibrium mixture of PAA, H 2 O 2 , and acetic acid [26], and the PAA-based Fenton system was defined as Fe 2+ /PAA/H 2 O 2 .…”

Evaluation of Fe2+/Peracetic Acid to Degrade Three Typical Refractory Pollutants of Textile Wastewater

et al. 2022

In this work, the degradation performance of Fe2+/PAA/H2O2 on three typical pollutants (reactive black 5, ANL, and PVA) in textile wastewater was investigated in comparison with Fe2+/H2O2. Therein, Fe2+/PAA/H2O2 had a high removal on RB5 (99%) mainly owing to the contribution of peroxyl radicals and/or Fe(IV). Fe2+/H2O2 showed a relatively high removal on PVA (28%) mainly resulting from ·OH. Fe2+/PAA/H2O2 and Fe2+/H2O2 showed comparative removals on ANL. Additionally, Fe2+/PAA/H2O2 was more sensitive to pH than Fe2+/H2O2. The coexisting anions (20–2000 mg/L) showed inhibition on their removals and followed an order of HCO3− > SO42− > Cl−. Humic acid (5 and 10 mg C/L) posed notable inhibition on their removals following an order of reactive black 5 (RB5) > ANL > PVA. In practical wastewater effluent, PVA removal was dramatically inhibited by 88%. Bioluminescent bacteria test results suggested that the toxicity of Fe2+/PAA/H2O2 treated systems was lower than that of Fe2+/H2O2. RB5 degradation had three possible pathways with the proposed mechanisms of hydroxylation, dehydrogenation, and demethylation. The results may favor the performance evaluation of Fe2+/PAA/H2O2 in the advanced treatment of textile wastewater.
