Management of Water Treatment Plant Residuals


Book Description

Potable water treatment processes produce safe drinking water and generate a wide variety of waste products known as residuals, including organic and inorganic compounds in liquid, solid, and gaseous forms. In the current regulatory climate, a complete management program for a water treatment facility should include the development of a plan to remove and dispose of these residuals in a manner that meets the crucial goals of cost effectiveness and regulatory compliance. This comprehensive water treatment residuals management plan should involve the: 1) Characterization of the form, quantity, and quality of the residuals; 2) determination of the appropriate regulatory requirements; 3) identification of feasible disposal options; 4) selection of appropriate residuals processing/treatment technologies; and development of a residuals management strategy that meets both the economic and noneconomic goals established for a water treatment facility. This manual provides general information and insight into each of these activities that a potable water treatment facility should perform in developing a residuals management plan.




Management of Water Treatment Plant Residuals


Book Description

This manual provides general information and insight into the development of a comprehensive water treatment residuals management plan for potable water treatment facilities. Readers gain an understanding of how to characterize the form, quantity, and quality of the residuals; determine the appropriate regulatory requirements; identify feasible disposal options; select appropriate residuals processing/treatment technologies; and develop a residuals management strategy that meets both the economic and noneconomic goals established for a water treatment facility. Addressed primarily are those residuals produced by coagulation/filtration plants, precipitative softening plants, membrane separation, ion exchange (IX), and granular activated carbon (GAC) absorption. In addition, available treatment technologies for gaseous residuals including stripping, odor control, gaseous chemical leak treatment, and ozonation are described.




Advances in Water and Wastewater Treatment


Book Description

Annotation "Advances in Water and Wastewater Treatment provides state-of-the-art information on the application of innovative technologies for water and wastewater treatment with an emphasis on the scientific principles for pollutant or pathogen removal. Described in detail are the practice and principles of wastewater treatment on topics such as: global warming, sustainable development, nutrient removal, bioplastics production, biosolid digestion and composting, pathogen reduction, metal leaching, secondary clarifiers, surface and subsurface constructed wetland, and wastewater reclamation. Environmental engineers and scientists involved in the practice of environmental engineering will benefit from the basic principles to innovation technologies application."--BOOK JACKET.

Water and Wastewater Engineering


Book Description

An In-Depth Guide to Water and Wastewater Engineering This authoritative volume offers comprehensive coverage of the design and construction of municipal water and wastewater facilities. The book addresses water treatment in detail, following the flow of water through the unit processes and coagulation, flocculation, softening, sedimentation, filtration, disinfection, and residuals management. Each stage of wastewater treatment--preliminary, secondary, and tertiary--is examined along with residuals management. Water and Wastewater Engineering contains more than 100 example problems, 500 end-of-chapter problems, and 300 illustrations. Safety issues and operation and maintenance procedures are also discussed in this definitive resource. Coverage includes: Intake structures and wells Chemical handling and storage Coagulation and flocculation Lime-soda and ion exchange softening Reverse osmosis and nanofiltration Sedimentation Granular and membrane filtration Disinfection and fluoridation Removal of specific constituents Drinking water plant residuals management, process selection, and integration Storage and distribution systems Wastewater collection and treatment design considerations Sanitary sewer design Headworks and preliminary treatment Primary treatment Wastewater microbiology Secondary treatment by suspended and attached growth biological processes Secondary settling, disinfection, and postaeration Tertiary treatment Wastewater plant residuals management Clean water plant process selection and integration




Management of Concentrate from Desalination Plants


Book Description

Management of Concentrate from Desalination Plants provides an overview of the alternatives for managing concentrate generated by brackish water and seawater desalination plants, as well as site-specific factors involved in the selection of the most viable alternative for a given project, and the environmental permitting requirements and studies associated with their implementation. The book focuses on widely used alternatives for disposal of concentrate, including discharge to surface water bodies; disposal to the wastewater collection system; deep well injection; land application; evaporation; and zero liquid discharge. Direct discharge through new outfall; discharge through existing wastewater treatment plant outfall; and co-disposal with the cooling water of existing coastal power plant are thoroughly described, and design guidance for the use of these concentrate disposal alternatives is presented with engineers and practitioners in the field of desalination in mind. Key advantages, disadvantages, environmental impact issues, and possible solutions are presented for each discharge alternative. Easy-to-use graphs depicting construction costs as a function of concentrate flow rate are provided for all key concentrate management alternatives. - Gives a critical overview of the latest practices and technological advancements in managing concentrate - Discusses the relationship between concentrate quality and quantity and other desalination processes - Provides design and cost guidance information to assist practitioners with the selection and sizing of the most commonly practiced concentrate disposal alternatives




Watershed Management for Potable Water Supply


Book Description

In 1997, New York City adopted a mammoth watershed agreement to protect its drinking water and avoid filtration of its large upstate surface water supply. Shortly thereafter, the NRC began an analysis of the agreement's scientific validity. The resulting book finds New York City's watershed agreement to be a good template for proactive watershed management that, if properly implemented, will maintain high water quality. However, it cautions that the agreement is not a guarantee of permanent filtration avoidance because of changing regulations, uncertainties regarding pollution sources, advances in treatment technologies, and natural variations in watershed conditions. The book recommends that New York City place its highest priority on pathogenic microorganisms in the watershed and direct its resources toward improving methods for detecting pathogens, understanding pathogen transport and fate, and demonstrating that best management practices will remove pathogens. Other recommendations, which are broadly applicable to surface water supplies across the country, target buffer zones, stormwater management, water quality monitoring, and effluent trading.













Principles of Water Treatment


Book Description

Principles of Water Treatment has been developed from the best selling reference work Water Treatment, 3rd edition by the same author team. It maintains the same quality writing, illustrations, and worked examples as the larger book, but in a smaller format which focuses on the treatment processes and not on the design of the facilities.
