Fitzhenry, Kelly, Barrett, Maria, O’Flaherty, Vincent, Dore, William, Cormican, Martin, Rowan, Neil, & Clifford, Eoghan. (2016). The effect of wastewater treatment processes, in particular ultraviolet light treatment, on pathogenic virus removal: EPA Research Report 171: Environmental Protection Agency.
Format: pdf Download now Municipal wastewater treatment plant discharges are a recognised source of human pathogenic viruses. Of concern within this group is norovirus the leading cause of viral gastroenteritis worldwide. This project investigated the use of FRNA bacteriophage as (i) a potential surrogate for norovirus response/behaviour and (ii) a model to determine the fate of viruses through a municipal wastewater treatment plant. The project also evaluated the efficacy of membrane filtration (microfiltration and ultrafiltration) as pathogen removal method and two ultraviolet-based technologies; pulsed UV and low pressure UV as pathogen disinfection methods. The potential impacts of parameters suchas organic carbon, metals and suspended solids, (typically present in wastewater) on the investigated pathogen removal processes were also analysed.
