Removal of Micro-organisms During Water Treatment
ISBN: 1 84057 553 0
Water companies are being encouraged to take an integrated approach to assessing and managing risks through the entire supply chain from catchment to tap. In this study, data have been extracted from the recent literature and used to derive indicative values for removal efficiencies of waterborne pathogens that can be achieved by the processes used in water treatment, including ozone and UV but not chlorine or chlorine-based disinfectants. This information could be used to validate the performance of these processes and may allow their contribution to be taken into account when setting an appropriate treatment policy for disinfection within the Drinking Water Safety Plan.
