Book Description
In a world where there is a growing awareness of the possible effects of human activities on climate change, there is a need to identify the emission of greenhouse gases (GHG) from wastewater treatment plants (WWTPs). As a result of this growing awareness, governments started to implement regulations that require water authorities to report their GHG emissions. With these developments there exists a strong need for adequate insight into the emissions of N2O and CH4. With this insight water authorities would be able to estimate and finally reduce their emissions. The overall objectives of the different research programs performed by partners of the GWRC members WERF (United States of America), WSAA (Australia), CIRSEE-Suez (France) and STOWA (the Netherlands) were: To define the origin of N2O emission. To understand the formation processes of N2O. To identify the level of CH4 emissions from wastewater collection and treatment systems. To evaluate the use of generic emission factors to estimate the emission of N2O from individual plants

Book Description
FROM THE PREFACE Wastewater collection systems are dynamic, not static. There is no single maintenance method, equipment, or technique that works best. Keeping an open mind, trying new techniques and technologies benefits sewer system operators. No two collection systems are alike. Maintenance staffing, skill levels, equipment, budgets, age and complexity of the system make each agency unique. However, collection systems do have many traits and problems in common. Based on inventory and analysis, problems are identified. Defects may then be prioritized, and corrective maintenance operations put into effect. Preventive maintenance techniques can be applied to all collection systems. Preventive maintenance is cost-effective; it strives to prevent problems from occurring rather than reacting to difficult situations and "putting out fires." This book examines problems shared by all agencies: roots, grease, deterioration, hydraulic inefficiencies and structural defects. New solutions to age-old problems are applied: TV inspection and video interpretation, rehabilitation analysis and trenchless technologies. Computerized maintenance management and GIS softwares are discussed. Jetting, line cleaning and exciting developments in nozzle technology are included. Roots and chemical root control foam, wastewater control and grease are major topics as well. Wastewater Collection System Maintenance shares insights drawn from operator experience, trial and error, successes and failures in the field, interviews and years of research and studies. A user-friendly rating and evaluation system is explained and applied to field conditions. Equipment operation and maintenance, and "tricks of the trade" are also discussed. As cities grow, new systems are extended upstream from older sewers. Many of these core drainage basins are now under capacity and in need of capital improvement projects. There are approximately 600,000 miles of sanitary sewers in the country. Nationwide, there exists a huge backlog of sewer pipes that need rehabilitation. Replacement would cost many billions of dollars. Maintenance operators are entrusted with the care and feeding of an aging sewer infrastructure.

Book Description
This comprehensive book by one of the foremost authorities in the field offers systematic and analytical coverage of the "how and why" of intelligence collection across its three major stages—the front end (planning), collection, and the back end (processing, exploitation, and dissemination). The book provides a fresh, logical, and easily understandable view of complex collection systems used worldwide. Its ground-breaking organizational approach facilitates understanding and cross-INT collaboration, highlighting the similarities and differences among the collection INTs. The first part of the book explains how the literal INTs—open source, human intelligence, communications intelligence, and cyber collection—work. The second part focuses on nonliteral or technical INTs including imagery, electronic intelligence, and measurements and signatures intelligence. All chapters use a common format based on systems analysis methodology, detailing function, process, and structure of the collection disciplines. The third part is a complete chapter discussing the complexities of collection management in the United States. Rich, full color illustrations accompany the text with examples throughout the book on topics as diverse as battlespace situational awareness, terrorism, weapons proliferation, criminal networks, treaty monitoring, and identity intelligence.
