Inactivation of Microorganisms by Chlorine, Chlorine Dioxide and Monochloramine During the Final Stage of Disinfection in Water Treatment

 
Price: £100  

Chemical inactivation forms the final barrier in water treatment with free (available) chlorine being the predominant process. This study has compiled recently available data on its ability to inactivate a range of waterborne pathogens, especially viruses. For comparative purposes, chlorine dioxide and monochloramine were included within this review although not commonly used for this purpose in the UK.

Despite certain inconsistencies in the data, the findings support the view that a Ct of 15mg.min/l, widely adopted as a benchmark in the UK, is capable of achieving a minimum 4-log reduction in numbers of common waterborne viruses and bacteria under conditions normally experienced during treatment. This work will enable water companies to demonstrate the validity of their disinfection policies.
