Download Wastewater Microbiology Book in PDF, ePub and Kindle
Wastewater Microbiology focuses on microbial contaminants found in wastewater, methods of detection for these contaminants, and methods of cleansing water of microbial contamination. This classic reference has now been updated to focus more exclusively on issues particular to wastewater, with new information on fecal contamination and new molecular methods. The book features new methods to determine cell viability/activity in environmental samples; a new section on bacterial spores as indicators; new information covering disinfection byproducts, UV disinfection, and photoreactivation; and much more. A PowerPoint of figures from the book is available at ftp://ftp.wiley.com/public/sci_tech_med/wastewater_microbiology.

Download Reduction of Pathogens, Indicator Bacteria, and Alternative Indicators by Wastewater Treatment and Reclamation Processes Book in PDF, ePub and Kindle
In wastewater reclamation systems, microbiological monitoring is conducted to ensure that the users of reclaimed water are exposed to minimal risks from exposure to pathogens. Typically, utilities rely on the use of process controls to remove or inactivate pathogens. Routine monitoring of indicator organisms is conducted to evaluate overall process performance and for regulatory compliance. However, the effectiveness of individual treatment processes for removal of pathogens is dependent on process variables. This project was conducted to compare the effectiveness of biological treatment, filtration, and disinfection for removal of bacterial and viral indicators, enteric viruses, and protozoan pathogens. Six full-scale treatment facilities were each sampled a minimum of four times over a one year period. The relative impacts of loading conditions, process design, and operating parameters on the removal/inactivation of a suite of nine microbial species (bacteria, coliphages, enteric viruses, and protozoan pathogens) was evaluated. Bacterial removal was consistent for all types of biological systems, however, increased virus removal was associated with biological nutrient removal and nitrification processes. Parasite removal was highly variable. The effectiveness of filtration was impacted most by the use of upstream chemicals (either chlorine or coagulant chemicals). Chlorine disinfection was more effective in cases where ammonia levels were low (biological nutrient removal or nitrification facilities). Infectivity assays for protozoan pathogens suggest that the proportion of infective cysts or oocysts increases with increasing level of treatment.

Download Wastewater Bacteria Book in PDF, ePub and Kindle
A practical guide to wastewater bacteria and the roles they perform in wastewater treatment Communicating material in a practical manner for operators and technicians who regulate and troubleshoot their wastewater treatment processes, Wastewater Bacteria discusses the effective control and proper operation of aerobic (activated sludge) and anaerobic (anaerobic digesters) biological treatment units to ensure that an adequate, active, and appropriate population of bacteria is present in each treatment unit. It is a hands-on guide to understanding the biology and biological conditions that occur at each treatment unit. Avoiding unnecessary technical jargon and chemical equations, Wastewater Bacteria, the fifth book in the Wastewater Microbiology Series, explores and explains: * Bacteria and the wastewater environment * Enzymes and sludge production * Nitrogen, phosphorus, and sulfur bacteria * Floc formation and filamentous organisms * Nitrification and denitrification * Sulfate reduction, fermentation, and methane production * Toxicity * Foam and malodor production The goal of Wastewater Bacteria is to enable plant operators to achieve the twofold basic objectives of wastewater treatment-to degrade organic wastes to a level where a significant, dissolved oxygen demand is not exerted upon receiving waters and to remove nutrients to levels where photosynthetic organisms in receiving waters are limited in their growth. This straightforward manual equips plant technicians to meet these objectives with essential information to understand the biological processes and organisms involved in wastewater treatment.

Download Indicators for Waterborne Pathogens Book in PDF, ePub and Kindle
Recent and forecasted advances in microbiology, molecular biology, and analytical chemistry have made it timely to reassess the current paradigm of relying predominantly or exclusively on traditional bacterial indicators for all types of waterborne pathogens. Nonetheless, indicator approaches will still be required for the foreseeable future because it is not practical or feasible to monitor for the complete spectrum of microorganisms that may occur in water, and many known pathogens are difficult to detect directly and reliably in water samples. This comprehensive report recommends the development and use of a "tool box" approach by the U.S Environmental Protection Agency and others for assessing microbial water quality in which available indicator organisms (and/or pathogens in some cases) and detection method(s) are matched to the requirements of a particular application. The report further recommends the use of a phased, three-level monitoring framework to support the selection of indicators and indicator approaches.Â

Download Fundamentals of Wastewater-Based Epidemiology Book in PDF, ePub and Kindle
It is common practice to evaluate wastewater to understand drug consumption, from antibiotics to illegal narcotics, and even to analyze dietary habits and trends. Evaluating contaminants in wastewater enables researchers, environmental scientists, and water quality experts to gain valuable information and data. Wastewater-based epidemiology is an emerging science that has proven to be a cost- and time-effective biomonitoring tool. This book provides a roadmap for detecting wastewater-borne pathogenic contaminants such as viruses, bacteria, fungi, and others. It provides a basic, fundamental discussion of how sampling and monitoring of wastewater using epidemiological concepts and practices can aid in determining the presence of the COVID-19 virus in a community, for example, and may help predict future outbreaks. Features • Offers a unique discussion of the detection of bacteria, fungi, and COVID-19, and other viruses in wastewater • Presents the fundamentals of wastewater chemistry and microbiology • Explains biomonitoring, sampling, testing, and health surveillance in a practical manner Fundamentals of Wastewater-Based Epidemiology: Biomonitoring of Bacteria, Fungi, COVID-19, and Other Viruses is an invaluable resource to a wide array of readers with varying interests and backgrounds in water science and public health.
