Presence of enteric viruses in freshwater and their removal by the conventional drinking water treatment process.
A review of results published in English or French between 1980 and 1990 was carried out to determine the levels of indigenous human enteric viruses in untreated surface and subsurface freshwaters, as well as in drinking water that had undergone the complete conventional treatment process. For this purpose, the conventional treatment process was defined as an operation that included coagulation...
متن کاملAssessment of the removal and inactivation of influenza viruses H5N1 and H1N1 by drinking water treatment.
Since 2003, there has been significant concern about the possibility of an outbreak of avian influenza virus subtype H5N1. Moreover, in the last few months, a pandemic of a novel swine-origin influenza A virus, namely A(H1N1), has already caused hundreds of thousands of human cases of illness and thousands of deaths. As those viruses could possibly contaminate water resources through wild birds...
متن کاملTrichloroethylene removal from water by ferrate treatment
In this study trichloroethylene (TCE) removal from model solutions and groundwater by ferrate treatment was investigated applying different initial TCE concentrations, ferrate dosages and pH values. TCE concentrations were measured both in the vapor and liquid phases of water samples with head space gas chromatograph mass spectrometer (HS/GC-MS) and solid phase micro-extraction gas chromatograp...
متن کاملRemoval of pharmaceuticals during drinking water treatment.
The elimination of selected pharmaceuticals (bezafibrate, clofibric acid, carbamazepine, diclofenac) during drinking water treatment processes was investigated at lab and pilot scale and in real waterworks. No significant removal of pharmaceuticals was observed in batch experiments with sand under natural aerobic and anoxic conditions, thus indicating low sorption properties and high persistenc...
متن کاملApplicability of quantitative PCR for determination of removal efficacy of enteric viruses and Cryptosporidium by water treatment processes.
This study aims to assess the applicability of quantitative PCR (qPCR) for removal studies of adenovirus, coxsackievirus, echovirus and Cryptosporidium by water treatment processes. Bench-scale coagulation jar tests were performed using the enteric viruses and Cryptosporidium. Standard methods (conventional cell-culture methods for the viruses and an immunofluorescence assay (IFA) for Cryptospo...
