| Popis: | There have been multiple reports of COVID‐19 virus, SARS‐CoV‐2 RNA presence in influent wastewater of water reclamation facilities (WRFs) across the world. In this study, the removal of SARS‐CoV‐2 RNA was investigated in a WRF by collecting samples from various stages relayed to hydraulic retention time (HRT) and analyzed for viral RNA (N1 and N2) gene markers and wastewater characteristics. SARS‐CoV‐2 RNA was detected in 28 out of 28 influent wastewater and primary effluent samples. Secondary effluent showed 4 out of 9 positive samples, and all tertiary and final effluent samples were below the detection limit for the viral markers. The reduction was significant (p value The graphical abstract demonstrates the collection locations of the samples across the treatment train, followed by the step by step pretreatment and virus concentration methods required based on sample type. |
