Download or read book Inactivation of Pathogens with Innovative UV Technologies written by and published by American Water Works Association. This book was released on 2004 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
