Comparison of UV, Peracetic Acid and Sodium Hypochlorite Treatment in the Disinfection of Urban Wastewater

Abstract: 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) a… Show more

“…livestock production, food industries and slaughterhouses) [35], the absence of these bacteria could be related to a low circulation of these pathogens in the local population. The absence of STEC and pathogenic Campylobacter (jejuni and coli) in wastewater samples was also reported in other studies [6,32,36].…”

“…These results highlight a greater sensitivity of the molecular method over the culture method. This is probably related to the difficulty of isolating Salmonella on culture media due to the presence of interfering microflora, as previously reported [32] or to the use of an enrichment step for the molecular method that can aid the recovery of injured, stressed or lag-phase bacterial cells [33]. Moreover, Salmonella spp.…”

“…Scientists of Kyrgyzstan pay special attention to the toxic and carcinogenic properties of some components of wastewater from industry and municipal services (4)(5)(6) . Modern scientists S. Bonetta et al (7,8) and H. Hamdhani et al (9) come to the conviction that many destructive changes in aquatic ecosystems, difficult to regenerate, are provoked by large-scale releases of toxic substances from industrial processes. The conclusions of scientists are complemented by a group of researchers led by S. Lu et al (10) and M. Preisner (11) are convinced of the special urgency of the impact on natural reservoirs of new understudied pollutants, which actually cannot be treated even with satisfactory condition of complete wastewater treatment systems.…”
