This book was released on 1990-02-07 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive volume provides a state-of-the-art review of the analysis and treatment of drinking water for microbial contamination, the direct cause of diseases and infant mortality primarily in the third world, but affecting industrialized countries as well. As a result of growing concern over waterborne epidemics, the 1980s were dedicated as the International Drinking Water Supply and Sanitation Decade by the United Nations. This book aims to summarize the results of this period of intensified research in a collection that will be of value to microbiologists, engineers, epidemiologists, sanitarians, health officials and scientists within governmental and international agencies as well as others interested in drinking water microbiology. Each chapter combines basic principles with recent research results, leading the reader from the microbiology of source water to that of drinking water treatment and distribution as well as the discussion of prominent pathogenic organisms, and concludes with testing methods, monitoring and statistical approaches.

Available in PDF, EPUB and Kindle. Book excerpt: Growth ("regrowth") of bacteria In drinking water distribution systems results in a deterioration of the water quality. Regrowth of chemoheterotrophic bacteria depends on the presence of organic. compounds that serve as a nutrient source for these bacteria. A batch-culture technique was developed to study the growth of bacteria in drinking water. The maximum colony counts of selected pure cultures of bacteria grown in drinking water were used as a measure for the concentration of easily assimilable organic carbon compounds (AOC). Three strains of bacteria isolated from drinking water were selected for AOC determinations: (1) Pseudomonas fluorescens strain P17, an organism with a very great nutritional versatility, for general use; (2) a Flavobacterium sp. strain S12, to determine the concentration of maltose and starch-like compounds, and (3) a Spirillum sp. strain NOX to determine the concentration of carboxylic acids. Including oxalic acid. The properties of these bacteria were extensively studied in batch-culture experiments with drinking water supplemented with very low amounts of selected organic compounds. The obtained results prove that growth and growth kinetics of bacteria at concentrations between 1 and 1000 micro-g of C per liter can be determined in simple experiments using simple equipment. The strains mentioned above were well adapted to growth at concentrations of a few micrograms of substrate C per liter; their substrate saturation constants (K s ) were below 1 micro-M for many compounds tested. K s values below 0.1 micro-M were also obtained. Growth measurements with strain P17 in water sampled from various treatment stages revealed that the AOC concentrations in these water types usually varied between 10 and 100 micro-g of acetate C equivalents per liter. Ozonation caused a strong increase of the AOC concentration. Strain NOX was better suited for the determination of the AOC concentration in ozonated water because of its ability to utilize oxalate. Filtration processes caused significant reductions of the AOC concentrations, at low AOC concentrations (

Book excerpt: Beginning with the germ theory of disease in the 19th century and extending through most of the 20th century, microbes were believed to live their lives as solitary, unicellular, disease-causing organisms . This perception stemmed from the focus of most investigators on organisms that could be grown in the laboratory as cellular monocultures, often dispersed in liquid, and under ambient conditions of temperature, lighting, and humidity. Most such inquiries were designed to identify microbial pathogens by satisfying Koch's postulates.3 This pathogen-centric approach to the study of microorganisms produced a metaphorical "war" against these microbial invaders waged with antibiotic therapies, while simultaneously obscuring the dynamic relationships that exist among and between host organisms and their associated microorganisms-only a tiny fraction of which act as pathogens. Despite their obvious importance, very little is actually known about the processes and factors that influence the assembly, function, and stability of microbial communities. Gaining this knowledge will require a seismic shift away from the study of individual microbes in isolation to inquiries into the nature of diverse and often complex microbial communities, the forces that shape them, and their relationships with other communities and organisms, including their multicellular hosts. On March 6 and 7, 2012, the Institute of Medicine's (IOM's) Forum on Microbial Threats hosted a public workshop to explore the emerging science of the "social biology" of microbial communities. Workshop presentations and discussions embraced a wide spectrum of topics, experimental systems, and theoretical perspectives representative of the current, multifaceted exploration of the microbial frontier. Participants discussed ecological, evolutionary, and genetic factors contributing to the assembly, function, and stability of microbial communities; how microbial communities adapt and respond to environmental stimuli; theoretical and experimental approaches to advance this nascent field; and potential applications of knowledge gained from the study of microbial communities for the improvement of human, animal, plant, and ecosystem health and toward a deeper understanding of microbial diversity and evolution. The Social Biology of Microbial Communities: Workshop Summary further explains the happenings of the workshop.

Available in PDF, EPUB and Kindle. Book excerpt: An essential resource containing the latest breakthroughs in the characterization, treatment and removal of Natural Organic Matter (NOM) from drinking water, Natural Organic Matter in Waters: Characterization and Treatment Methods focuses on advance filtration and treatment options, and processes for reducing disinfection by-products. Based on the author's years of research and field experience, this book begins with the characterization of NOM including: general parameters, isolation and concentration, fractionation, composition and structural analysis and biological testing. This is followed by removal methods such as inorganic coagulants, polyelectrolytes and composite coagulants. Electrochemical and membranes removal methods such as: electrocoagulation, electrochemical oxidation, microfiltration and ultrafiltration, nanofiltration and membrane fouling. This book covers conventional as well as advanced NOM removal methods, includes characterization methods of NOM, and explains removal methods such as: removal by coagulation, electrochemical, advanced oxidation, and integrated methods. The book provides researchers with a discussion of NOM removal by advanced oxidation processes, adsorption and ion exchange. In addition, engineers and researchers will find Natural Organic Matter in Waters: Characterization and Treatment Methods a valuable guide for integrating methods, processes and technologies to achieve the desired effect.
