Impact of ozonation and biological post-treatment of municipal wastewater on microbiological quality parameters

Abstract

Ozonation is an established process for advanced wastewater treatment, with a dose-depending degree of disinfection. It is generally followed by biological post-treatment with the main objective of oxidation by-product abatement....

Addressing main challenges in the tertiary treatment of urban wastewater: are homogeneous photodriven AOPs the answer?

“…148 The effect of BAC on AR control and pathogens as ozonation post-treatment was also investigated but did not significantly improve the ARGs ( intl 1 and sul 1) and pathogens (but for C. perfringens and somatic coliphages) compared to the ozonation process alone. 149…”

“…148 The effect of BAC on AR control and pathogens as ozonation post-treatment was also investigated but did not significantly improve the ARGs (intl1 and sul1) and pathogens (but for C. perfringens and somatic coliphages) compared to the ozonation process alone. 149 Solar-driven homogenous AOPs seem to be an attractive option alternative to ozonation for the tertiary treatment of urban wastewater in small WTPs. SPF with EDDS has been compared to the ozonation process in the inactivation of pathogens, 104 CECs removal, and effect on the final toxicity.…”

Occurrence and Quantitative Microbial Risk Assessment of Methicillin-Resistant Staphylococcus aureus (MRSA) in a Sub-Catchment of the Yodo River Basin, Japan

“…The prevalence of S. aureus and MRSA was estimated by screening microbes grown on different chromogenic agar media: CHROMID S. aureus Elite for S. aureus and CHROMID MRSA for MRSA (bioMérieux S.A., Marcy-l’Étoile, France). Bacterial identification was carried out as per the manufacturer’s instructions and using previously described methods [ 31 , 36 , 37 , 38 , 39 ].…”
