(range between 2 and 7 log GU/L) and the presence of Leg. with the culture method required by EU regulation, high concentrations of Legionella spp. In addition, despite the absence of Legionella spp. in effluent disinfected with ClO 2 (17% of samples) showed the need to control the quality of this effluent. coli (range between 0.88 and 5.21 Log MPN/100 mL) and contamination by Salmonella spp. The results obtained showed good abatement performance for WWTPs equipped with MBR. Moreover a comparison between molecular and culture methods was discussed. The bacteria detection was compared in different wastewater plants with membrane bioreactor (MBR) system or with disinfection step with chlorine dioxide (ClO 2 ). Culture method was also used for the enumeration of different microbial indicators. and Legionella were detected with both cultural and molecular methods (PCR and q-PCR, respectively). coli that produce Shiga toxins (STEC) and thermotolerant Campylobacter were monitored using an enrichment step associated with specific PCR, while Salmonella spp.

The purpose of this work was to investigate the role of wastewater treatment on microbiological contamination by evaluating the possible risks associated with wastewater effluent reuse, taking into account new EU legislation (2020/741) on minimum requirements for water reuse. However, if not adequately treated, wastewater represents a source of microbiological health risk. Wastewater reuse represents a promising alternative source of water supply considering the water scarcity related to climate change.
