This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Statistically-designed factorial experiments were conducted using 'synthetic' waters to examine the effects of various physical/chemical parameters on chlorine dioxide-related disinfection by-product formation. 2-level factorial experiments were then performed on 7 surface waters and a groundwater collected in Ontario to develop statistically-based model equations capable of predicting chlorine dioxide consumption, chlorite and chlorate formation when dosing with chlorine dioxide. These equations were developed in terms of pH, temperature, chlorine dioxide concentration, reaction time and water organic content. Interaction effects involving the aforementioned parameters were also included in the model equations, improving the accuracy of the predictive equations in fitting measured levels as evaluated through internal and external validations. Chlorine-dioxide dose and water organic content were found to be key parameters in developing the predictive equations. Improved correlations between chlorine dioxide consumption, chlorite and chlorate formation with changes in UV$\sb{254}$ were found to exist on a site-and parameter-specific basis.

Download or read book Modelling Chlorine Dioxide s Inactivation of Microbial Indicators and Disinfection By product Formation written by Liza Ballantyne and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of chlorine dioxide to drinking water treatment was studied at bench- and pilot-scale during this research. The impact of water quality parameters including bromide level, pH, chlorine dioxide dose and purity, and secondary disinfectant type on the formation of disinfection by-product (DBP) was examined by performing 2-level factorial experiments DBPs measured during the experiments included chlorite, chlorate, trihalomethanes, haloacetic acids, bromate and adsorbable organic halides. Results showed that both pH and chlorine dioxide dose had the greatest impact on chlorite and chlorate. In addition, site-specific mathematical models which incorporated disinfectant chemistry characteristics, inactivation kinetics and contactor hydraulics to accurately estimate the inactivation of stressed and non-stressed microbial indicators (MS 2 phages and 'Bacillus subtilis' spores) for ' Giardia lamblia' and 'Cryptosporidium parvum' were developed. Results revealed that filtration/physical stress damaged the microbial cell membrane thereby rendering the microorganisms more susceptible to chlorine dioxide inactivation.

This book was released on 2011-09-20 with total page 1109 pages. Available in PDF, EPUB and Kindle. Book excerpt: New edition covers the latest practices, regulations, and alternative disinfectants Since the publication of the Fourth Edition of White's Handbook of Chlorination and Alternative Disinfectants more than ten years ago, the water industry has made substantial advances in their understanding and application of chlorine, hypochlorite, and alternative disinfectants for water and wastewater treatment. This Fifth Edition, with its extensive updates and revisions, reflects the current state of the science as well as the latest practices. Balancing theory with practice, the Fifth Edition covers such important topics as: Advances in the use of UV and ozone as disinfectants Alternative disinfectants such as chlorine dioxide, iodine, and bromine-related products Advanced oxidation processes for drinking water and wastewater treatment New developments and information for the production and handling of chlorine Latest regulations governing the use of different disinfectants For each disinfectant, the book explains its chemistry, effectiveness, dosing, equipment, and system design requirements. Moreover, the advantages and disadvantages of each disinfectant are clearly set forth. References at the end of each chapter guide readers to the primary literature for further investigation. Authored and reviewed by leading experts in the field of water and wastewater treatment, this Fifth Edition remains an ideal reference for utilities, regulators, engineers, and plant operators who need current information on the disinfection of potable water, wastewater, industrial water, and swimming pools.

This book was released on 2005-08-18 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The anthrax attacks in fall 2001 spurred an extensive and costly decontamination effort where many decisions had to be made about which sites required cleanup, what method to use, how to determine the effectiveness of the cleanup, and how "clean" the building had to be for reoccupation. As part of a project funded by the U.S. Department of Homeland Security (DHS), and managed by Lawrence Livermore National Laboratory, the National Research Council was asked to consider the criteria that must be met for a cleanup to be declared successful, allowing the reoccupation of a facility. The report finds that efficiently sampling and characterizing a pathogen is critical for choosing the best remediation strategy. However, there should be no universal standard for deciding when a building is safe to re-enter because varying pathogen amounts and characteristics could require different strategies. The report offers a flowchart for decision-makers that includes questions about the characteristics of the pathogen; how far it has spread; whether it is transmissible between humans; and how long it will survive to pose a threat. The report also recommends that a risk-assessment approach be adopted as part of a strategy for achieving a "socially acceptable" standard for cleanup.
