This book was released on 2001 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Waterborne transmission of disease has been documented throughout history. One of the greatest contributions to 20% century society has been the advent and application of water treatment technologies. However, analysis of current World Health Organization (WHO) estimates of illness and mortality and epidemiological investigations in the United States still indicates that the threat to public health from waterborne disease still exists There are a plethora of contaminants (both chemical and microbiological) that impose a direct risk to public health in the United States. The United States Environmental Protection Agency (EPA) reviews these contaminants and focuses its efforts upon the chemicals and microorganisms that are entered on the Contaminant Candidate List (CCL). Although it has never appeared on the CCL, a large amount of research during the 1990s was focused upon Cryptosporidium parvum, a pathogenic waterborne parasite, to fmd methods and techniques to measure, remove, and inactivate it in drinking water supplies. C. parvum gained national public attention in 1993 when cryptosporidiosis in Milwaukee, Wisconsin infected an estimated 403,000 people and killed an estimated 65 to 100 people (MacKenzie, et al., 1994).

This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chlorine dioxide inactivation of 'Cryptosporidium parvum' oocysts (Iowa isolate, genotype 2 (C)) was measured at bench scale in various water matrices using 'in vitro' excystation and a most probable number cell culture infectivity assay. 'In vitro' excystation underestimated inactivation compared to the infectivity assay. There was a significant difference (Ã = 0.05) in the inactivation of oocysts among the diverse water matrices measured by the infectivity assay but not by ' in vitro' excystation. A 'Ct' of 1000 mg·min/L was necessary for 2.0 log10 inactivation in type I deionised-distilled water adjusted to pH 8 at 22°C. This degree of resistance to chlorine dioxide by 'C. parvum' oocysts has not been quantified previously in the literature. 'Bacillus subtilis' spores (ATCC 19659) were found to be an unsuitable surrogate for 'C. parvum' oocysts in bench- and pilot-scale chlorine dioxide inactivation studies, but could function as a surrogate in pilot scale filtration removal studies.

This book was released on 2000 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cryptosporidium currently presents one of the most pressing challenges for the water industry. High-profile incidents have brought the problem to public attention, yet the technical difficulties of monitoring and eliminating "crypto" are significant. These selected proceedings summarise the work of many of the world's leading experts, who gathered in Paris to establish the state of our knowledge regarding Cryptosporidium, Giardia and other waterborne particles. The 27 papers deal with issues of detection, resource protection, particles separation techniques, disinfection and inactivation, and plant management. They provide essential information for all concerned with these issues whether for scientific research, regulation or utilities management.
