Download or read book Characterizing Microbial Water Quality in Reclaimed Water Distribution Systems written by R. Narasimhan and published by IWA Publishing. This book was released on 2006-06-30 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, reclaimed water systems met water quality and public health related standards at the end of the treatment facility prior to entering the distribution system. However, water quality within the reclaimed water distribution system can significantly change and affect end uses due to changes in levels of color, odor, and biofilm growth. Operations staff need guidance to help them optimize the reclaimed water quality in the distribution system throughout the year. The objectives of this project were to: characterize the nature and extent of water quality deterioration in reclaimed water distribution systems, including microbial fouling, regrowth, impact to the end user, and impact on reuse and other related regulations; identify pertinent water quality issues in relationship to degradation as it is conveyed to reuse customers; develop general guidance for use by reclaimed water utilities in identifying and assessing problems; and provide options for controlling regrowth including regulating detention time, flushing, and optimization of disinfectants. The final report includes a summary of state reclaimed water regulations and federal guidelines, and other related regulations. The research team put together a final report that provides general guidance for use by reclaimed water utilities in assessing and solving potential problems. Guidance for operation, monitoring, and maintenance of reclaimed water systems to improve quality for end users. Biofilm control methods such as pipeline flushing, shock chlorination, and intermittent use of chloramine disinfectant are discussed. The research also addresses methods for identifying microbially induced corrosion issues and methods to optimize operations through the use of monitoring and modeling activities. Disinfectant residual criteria for reclaimed water systems are presented to assist system operators.
Download or read book Characterizing and Managing Salinity Loadings in Reclaimed Water Systems written by Ken Thompson and published by American Water Works Association. This book was released on 2006 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of salinity in reclaimed water is growing as more utilities choose to use reclaimed water for irrigation and other purposes. This project is the first comprehensive look at this problem on a national level. The project conducted literature reviews on the sources of salinity to municipal wastewater and on constraints to using reclaimed water, conducted two surveys of utilities that reclaim water, and summarized regulations regarding reclaimed water. Salt balances were developed for sewersheds in five case study utilities integrating extensive field sampling, a household survey, and a newly developed model, Water Quality (WQ) Analyst. Finally, the net annualized cost of potential salinity mitigation practices was determined using an economics model. CD included with full Appendices.
Download or read book Microbial Quality of Water Supply in Distribution Systems written by Edwin E. Geldreich and published by CRC Press. This book was released on 2020-07-26 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hidden problems, buried deep in the pipe networks of water distribution systems, are very serious potential threats to water quality. Microbial Quality of Water Supply in Distribution Systems outlines the processes and issues related to the degradation of water quality upon passage through networks of pipes, storage reservoirs, and standpipes on its way to the consumer. The risks associated with biofilm accumulation, bacteria, and other contaminants are discussed in great detail. In addition to its excellent microbiological coverage of organisms in drinking water and biofilms in distribution systems, Microbial Quality of Water Supply in Distribution Systems provides clear treatments of the technical and public communication issues most commonly affecting the quality of water and water supply systems. The inclusion of numerous case histories in this new book makes it a complete reference source for anyone concerned with water quality and water distribution systems.

Download or read book Water Reuse written by National Research Council and published by National Academies Press. This book was released on 2012-07-17 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Expanding water reuse-the use of treated wastewater for beneficial purposes including irrigation, industrial uses, and drinking water augmentation-could significantly increase the nation's total available water resources. Water Reuse presents a portfolio of treatment options available to mitigate water quality issues in reclaimed water along with new analysis suggesting that the risk of exposure to certain microbial and chemical contaminants from drinking reclaimed water does not appear to be any higher than the risk experienced in at least some current drinking water treatment systems, and may be orders of magnitude lower. This report recommends adjustments to the federal regulatory framework that could enhance public health protection for both planned and unplanned (or de facto) reuse and increase public confidence in water reuse.

This book was released on 2007-01-22 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protecting and maintaining water distributions systems is crucial to ensuring high quality drinking water. Distribution systems-consisting of pipes, pumps, valves, storage tanks, reservoirs, meters, fittings, and other hydraulic appurtenances-carry drinking water from a centralized treatment plant or well supplies to consumers' taps. Spanning almost 1 million miles in the United States, distribution systems represent the vast majority of physical infrastructure for water supplies, and thus constitute the primary management challenge from both an operational and public health standpoint. Recent data on waterborne disease outbreaks suggest that distribution systems remain a source of contamination that has yet to be fully addressed. This report evaluates approaches for risk characterization and recent data, and it identifies a variety of strategies that could be considered to reduce the risks posed by water-quality deteriorating events in distribution systems. Particular attention is given to backflow events via cross connections, the potential for contamination of the distribution system during construction and repair activities, maintenance of storage facilities, and the role of premise plumbing in public health risk. The report also identifies advances in detection, monitoring and modeling, analytical methods, and research and development opportunities that will enable the water supply industry to further reduce risks associated with drinking water distribution systems.
Download or read book Microbiological Research In Agroecosystem Management written by Rajesh Kannan Velu and published by Springer Science & Business Media. This book was released on 2013-03-15 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroecosystem is an ideal dynamic functional system with a set of chemical and biological interaction taking place in plant surface either below or above the ground levels. These levels of interaction activities fundamentally with microorganism-plant-soil systems are extended upto the level of entire agricultural economy. Greatly simplified, the agroecosystems control the various range of energy flux, resources exchange, organic and inorganic nutrient budgets and population dynamics. The main aim of this edited volume is to provide a broad spectrum of agroecosystems structure, function and maintenance involved in microbial research. This book consists of 20 full length research articles focusing on the emerging problems in the field and the positive findings are identified on key areas of research such as biodiversity, ecosystem service, environmental cleaning in agroecology, etc. These articles are arranged progressively linking themselves thematically with photographs, figures and tables. Focused field articles are included which prove a valuable contribution to the field of agroecosystem management by microbial facilitations. The editor hopes that these articles would prompt the budding scholars to further their research which in turn would certainly help the agriculturists.
