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 2016-01-28 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers a detailed overview of currently applied and tested wastewater treatment technologies and the integration of advanced processes to remove trace organic contaminants and microorganisms. It discusses the potential of enhanced biological treatment to produce effluent suitable for reuse, new processes for urban wastewater disinfection and the reduction of antibiotic resistant bacteria, as well as the effect of advanced oxidation processes on wastewater microbiome and chemical contaminants. It also presents membrane bioreactors, moving bed bioreactors, light and solar driven technologies, ozonation and immobilised heterogeneous photocatalysis and provides an evaluation of the potential of constructed wetlands integrated with advanced oxidation technologies to produce wastewater safe for reuse. Furthermore, the volume discusses water reuse issues and standards, the status of membrane bioreactors applications, and the treatment of reverse osmosis concentrate for enhanced water recovery during wastewater treatment. Finally, it presents recent developments in potable water reuse and addresses various important issues in this framework, like the proper protection of public health, reliability and monitoring. This volume is of interest to experts, scientists and practitioners from various fields of research, including analytical and environmental chemistry, toxicology and environmental and sanitary engineering, as well as treatment plant operators and policymakers.
