Taschenbuch. Zustand: Neu. Neuware - Phosphorus in surface runoff from agricultural lands is often implicated in the degradation of surface water quality. Many states are developing soil phosphorus application limits. Utilities must develop and implement new best management practices (BMPs) to control phosphorous. The objective of this project was to investigate the beneficial use of water treatment residuals (WTRs) to control non-point source (NPS) phosphorus pollution and protect surface water quality. Specifically, the researchers planned to examine the unique chemical characteristics of WTRs, namely the large concentration of aluminum and iron hyrdroxides, to combine them with phosphorus in high phosphorus soils, biosolids, and manures to reduce the likelihood of phosphorus release to aquatic environments. Several types of WTRs were selected and characterized based on the coagulant used (aluminum and iron based) and their form - dewatered or liquid. The research developed valuable new insight for the beneficial use of WTRs and demonstrated WTRs' potential as a BMP for phosphorus control in surface runoff from agricultural lands and for protecting surface water quality. In particular, the potential role of WTRs in Phosphorous Index programs was confirmed. Future research and full-scale demonstrations are needed to confirm the potential of land applied WTRs as a BMP for phosphorus control in runoff from agricultural lands. Land application of WTRs within a utility s source water watershed, while subject to local and state regulations, can be implemented as part of an overall watershed protection program.…

Buch. Zustand: Neu. Neuware - Advanced Biological Treatment Processes for Industrial Wastewaters provides unique information relative to both the principles and applications of biological wastewater treatment systems for industrial effluents. Case studies document the application of biological wastewater treatment systems in different industrial sectors such as chemical, petrochemical, food-processing, mining, textile and fermentation. With more than 70 tables, 100 figures, 200 equations and several illustrations, the book provides a broad and deep understanding of the main aspects to consider during the design and operation of industrial wastewater treatment plants. Students, researchers and practitioners dealing with the design and application of biological systems for industrial wastewater treatment will find this book invaluable.…

Buch. Zustand: Neu. Neuware - This book examines and analyses the problems inherent in integrated water management in transboundary conditions. Integrated Transboundary Water Management in Theory and Practice provides new knowledge and policy recommendations based on the experiences and results of a major 3-year interdisciplinary research project (MANTRA-East). Drawing on extensive studies of the Lake Peipsi region in Estonia and Russia, the book explores the political and social issues surrounding transboundary water management and introduces the way that qualitative-quantitative-qualitative scenarios have been used in real-life situations. The book presents conclusions and policy recommendations for integrated transboundary water management that will be invaluable to water managers, policy-makers and academic researchers working in this rapidly expanding field.…

Buch. Zustand: Neu. Neuware - The strategic planning of urban water systems is a complex task. The Urban Water programme covered projects from various disciplines at 9 Swedish Universities, from 1999 to 2006. The projects developed a 'toolbox' for strategic planning of drinking-, waste- and stormwater management, covering aspects such as the environment, health and hygiene, financing, organisation, households, and technical function. Strategic Planning of Sustainable Urban Water Management synthesises the results and presents a comprehensive approach, which includes not only the technical, economic and environmental aspects, but also the challenges of institutional capacity and public participation in the planning process. Furthermore, the experience from a number of case studies are summarised and can offer readers inspiration for their own planning situations.…
