Wastewater Exploitation

Microbial Wastewater Treatment focuses on the exploitation of microorganisms as decontaminating tools to treat polluted wastewater, a worldwide concern. Microorganism-based processes are seen as promising technologies to treat the ever-increasing problem of polluted wastewater. The book covers recently developed process technologies to solve five major trends in the field of wastewater treatment, including nutrient removal and recovery, trace organic compounds, energy saving and production, sustainability and community involvement. Illustrates the importance of microorganisms in wastewater treatment Points out the reuse of the treated wastewater Highlights the recovery of resources from wastewater Pays attention to the occurrence of novel micro-pollutants Introduces new trends in wastewater technology

This book addresses how to estimate substance use and thereby evaluate policies intended to reduce the harms caused by drugs and other substances. Wastewater analysis (WWA) can provide efficient, affordable, fine-grained and objective data on population substance use trends on a very large scale. The authors discuss the potential implications of WWA as a new method for understanding substance use in a variety of settings and ignite a discourse with policy makers, criminologists, epidemiologists and other disciplines about the need for collaboration with WWA scientists. The book also features an explanation of the costs and harms of substance use with academic literature from criminological and epidemiological sources and reports from lead agencies. Additional features include: Details on the origin of wastewater analysis in environmental science Description of analytical chemistry methods for tracing a wide variety of substances, including illicit drugs, alcohol, tobacco and other chemicals Exploration of the major empirical problems in estimating population consumption of alcohol, tobacco and drugs at the international and national level Examination of the principles of human research ethics and their application to wastewater analysis Wastewater Analysis for Substance Abuse Monitoring and Policy Development is a valuable tool for analytical chemists, wastewater scientists and criminologists, as well as researchers and policy makers across disciplines who work in drug sectors.

The IWA Task Group for Mathematical Modelling of Anaerobic Digestion Processes was created with the aim to produce a generic model and common platform for dynamic simulations of a variety of anaerobic processes. This book presents the outcome of this undertaking and is the result of four years collaborative work by a number of international experts from various fields of anaerobic process technology. The purpose of this approach is to provide a unified basis for anaerobic digestion modelling. It is hoped this will promote increased application of modelling and simulation as a tool for research, design, operation and optimisation of anaerobic processes worldwide. This model was developed on the basis of the extensive but often disparate work in modelling and simulation of anaerobic digestion systems over the last twenty years. In developing ADM1, the Task Group have tried to establish common nomenclature, units and model structure, consistent with existing anaerobic modelling literature and the popular activated sludge models (See Activated Sludge Models ASM1, ASM2, ASM2d and ASM3, IWA Publishing, 2000, ISBN: 1900222248). As such, it is intended to promote widespread application of simulation from domestic (wastewater and sludge) treatment systems to specialised industrial applications. Outputs from the model include common process variables such gas flow and composition, pH, separate organic acids, and ammonium. The structure has been devised to encourage specific extensions or modifications where required, but still maintain a common platform. During development the model has been successfully tested on a range of systems from full-scale waste sludge digestion to laboratory-scale thermophilic high-rate UASB reactors. The model structure is presented in a readily applicable matrix format for implementation in many available differential equation solvers. It is expected that the model will be available as part of commercial wastewater simulation packages. ADM1 will be a valuable information source for practising engineers working in water treatment (both domestic and industrial) as well as academic researchers and students in Environmental Engineering and Science, Civil and Sanitary Engineering, Biotechnology, and Chemical and Process Engineering departments.

Development in Waste Water Treatment Research and Processes: Innovative Microbe-Based Applications for Removal of Chemicals and Metals in Wastewater Treatment Plants focuses on the exploitation of various biological treatment technologies and their use to treat toxic and hazardous contaminants present in industrial effluent and restore the contaminated sites, a topic which lacks discussion in existing titles on the global market. This book encompasses advanced technologies and updated information as well as future directions for young researchers and scientists who are working in the field of wastewater treatment or effluent treatment plants and biodegradation of environmental contaminants for environmental safety and sustainable development. Provides wide information to readers on state-of-the-art applications of microbes for wastewater/industrial effluent treatment and environmental protection Summarizes our current knowledge on the use of various microbes, even the use of dead biomass for dye decolorization and degradation Explores different aspects of biological methods for contaminant removal and better advanced biotechnological applications

This illustrated report sets out a global review of the state of the world's freshwater resources, based on the collective work of 24 United Nations agencies, following on from the conclusions of the first UN World Water Development Report 'Water for People, Water for Life' published in 2003 (ISBN 9231038818). This second edition discusses progress towards the water-related targets of the UN Millennium Development Goals and examines a range of key issues including population growth and increasing urbanisation, changing ecosystems, food production, health, industry and energy, as well as risk management, valuing and paying for water and increasing knowledge and capacity. It contains 16 case studies which consider key challenges in water resource management and makes a number of recommendations to guide future action and encourage sustainable use, productivity and management of our increasingly scarce freshwater resources.

This text is written by a number of authors from different countries and disciplines, affording the reader an invaluable and unbiased perspective on the subject of intensive groundwater development. Based on information gathered from the experience of many countries over the last decades, the text aims to present a clear discussion on the conventional hydrogeological aspects of intensive groundwater use, along with the ecological, legal, institutional, economic and social challenges. Divided into two main sections, the first group of authors put forward the positive and negative aspects of intensive groundwater use, whilst a second group provide an overview of the situation specific countries face as a consequence of this phenomenon. Fully revised and up-to-date, Groundwater Intensive Use makes a significant number of discoveries in a subject area that is topical in today's climate.

The book provides an elaborate treatment of groundwater prospecting and management covering remote sensing, geological–geophysical cum hydrogeological studies, exploration (geological and geophysical), development (well logging techniques, pump test, its analysis and applications in well design), contamination (pollution of groundwater) and regulatory legislations regarding groundwater utilization under one cover. The book presents an elucidation of fundamental and theoretical background of each technique supported by necessary illustrative examples and exclusive case studies. It is a text-cum-reference book not only for students, research scholars and practicing earth scientists but also for practicing civil and agricultural engineers working in the application of groundwater resources, engaged in its exploration, development, contamination, legislation and management. The general readers can also refer the book for understanding the groundwater domain for adequate knowledge, as groundwater resources are essential life support commodity which is replenishable but not inexhaustible.
