Pages : 112
Book Description
This research studied low pressure(LP), low pressure-high-output (LPHO, medium pressure(MP) and pulsed (PUV) UV Systems and their effects on various pathogens. Among the findings were: bacteria is more susceptible to UV light than viruses; some strains of E.coli had different dose responses without explanation; adenovirus serotypes 40 and 41 are highly resistant to UV inactivation and a residual disinfection process is recommended to follow UV disinfection. All details of the study and models are discussed thoroughly.
Coliforms in Distribution Systems
Author: Graham A. GagnonPublisher: American Water Works Association
ISBN: 1583215417
Category : Drinking water
Languages : en
Pages : 164
Book Description
The objective of this project is to understand the potential mechanisms of antimicrobial resistance of E. coli and opportunistic pathogens under disinfection conditions. The project involves molecular techniques to understand genetic changes in biofilm and suspended bacteria in response to different disinfectant conditions. It examines the effects of using single chemical disinfectants (free chlorine, chloramines, and chlorine dioxide) compared with UV light pretreatment, as well as the impact of pipe material (polycarbonate or cast iron) and E. coli mutations. Field studies include both surface water and groundwater.
