R4,289 Discovery Miles 42 890 Ships in 7 - 11 work days

At present, constructed wetlands for wastewater treatment are a widely used technology for treatment of various types of wastewaters. The International Water Association (then International Association on Water Pollution Research and Control) recognized wetlands as useful tools for wastewater treatment and est- lished the series of biennial conferences on the use of wetland systems for water pollution control in 1988. In about 1993, we decided to organize a workshop on nutrient cycling in natural and constructed wetlands with the major idea to bring together researchers working on constructed and also natural wetlands. It was not our intention to compete with IWA conferences, but the workshop should rather complement the series on treatment wetlands by IWA. We believed that the exchange of information obtained from natural and constructed wetlands would be beneficial for all participants. And the time showed that we were correct. The first workshop took place in 1995 at T?ebo? in South Bohemia and most of the papers dealt with constructed wetlands. Over the years we extended the topics on natural wetlands (such as role of wetlands in the landscape or wetland restoration and creation) and during the 6th workshop held at T?ebo? from May 30 to June 3, 2006, nearly half of 38 papers presented during the workshop dealt with natural wetlands. This workshop was attended by 39 participants from 19 countries from Europe, Asia, North and South Americas and Australia. The volume contains 29 peer-reviewed papers out of 38 papers which were presented during the workshop.

In the current age of science and technology, our lives have become dominated by countless scientific and technological innovations without which the earth would be a much poorer place. Life as we know would become absolutely bleak and boring without the inventions and advances being made all over the globe. In fact, scientific inventions, discoveries and innovations have ushered in a dramatic revolution in virtually every sphere of life. But at the same time, the skewed use of technology is at loggerheads with the environment. We, and our environment, now face a number of critical challenges and it is in response to this that we wrote this book to raise awareness for environmental issues and related management aspects. With a primary focus on Environmental Management - the rational reconciliation of man and nature, which involves the judicious exploitation and utilization of natural resources without disturbing the ecosystem's balance - it will thus help to improve the relationship between man and environment. Moreover, it offers a wealth of ready-to-use material for advanced undergraduate and graduate students of Environment and Water Management. The book systematically addresses a range of key aspects, e.g. scientific principles, methods and ideas, as well as life-long learning skills for students. Further, it provides a solid foundation for applying scientific approaches to environmental problems.

The Water Environment of Cities (Hardcover, 2009 ed.): Lawrence A. Baker The Water Environment of Cities (Hardcover, 2009 ed.)
Lawrence A. Baker
R4,303 Discovery Miles 43 030 Ships in 7 - 11 work days

The concept for the Water Environment of Cities arose from a workshop "Green 1 Cities, Blue Waters" workshop held in 2006. The workshop assembled experts from engineering, planning, economics, law, hydrology, aquatic ecology, geom- phology, and other disciplines to present research ?ndings and identify key new ideas on the urban water environment. At a lunch discussion near the end of the workshop, several of us came to the recognition that despite having considerable expertise in a narrow discipline, none of us had a vision of the "urban water en- ronment" as a whole. We were, as in the parable, blind men at opposite ends of the elephant, knowinga great deal about the parts, but notunderstandingthe whole. We quickly recognized the need to develop a book that would integrate this knowledge to create this vision. The goal was to develop a book that could be used to teach a complete, multidisciplinary course, "The Urban Water Environment," but could also be used as a supplemental text for courses on urban ecosystems, urban design, landscapearchitecture, water policy, waterqualitymanagement andwatershed m- agement. The book is also valuable as a reference source for water professionals stepping outside their arena of disciplinary expertise. The Water Environment of Cities is the ?rst book to use a holistic, interdis- plinary approach to examine the urban water environment. We have attempted to portrayaholisticvisionbuiltaround theconcept of water as a coreelement ofcities. Water has multipleroles: municipalwatersupply, aquatichabitat, landscapeaesth- ics, and recreation. Increasingly, urban water is reused, serving multiple purposes.

This book offers a meaningful and practicable guide to better management of arsenic problems in the groundwater of the Gangetic Plain. It gathers contributions from distinguished researchers who have been actively working in the area for over a decade. The arsenic contamination of groundwater is a growing concern in the central Gangetic Plain, where the local population's main sources of fresh water are surface water, groundwater and rain water; of these sources, only the last two generally meet the most important criteria for drinking water in their natural state. Natural geological changes are presumed to be the primary reason for arsenic contamination in this region. Further, most of the people living in this area have developed the habit of drinking water (groundwater) from the arsenic-contaminated tubewells in many parts of the region. As a result, many are suffering from arsenicosis and many more are at risk. Since the cause of arsenic contamination in groundwater still remains unclear, this book seeks to address the arsenic issue in this region by pursuing a holistic and systematic scientific approach. Accordingly, it delineates various sources, processes, hypotheses and remedial approaches that are needed to manage the arsenic contamination in the Central Gangetic Plain.

Carlos Ocampo-Martinez, Rudy R. Negenborn
R4,141 R1,985 Discovery Miles 19 850 Save R2,156 (52%) Ships in 12 - 17 work days

This book aims at stimulating discussion between researchers working on state of the art approaches for operational control and design of transport of water on the one hand and researchers working on state of the art approaches for transport over water on the other hand. The main contribution of the book as a whole is to present novel perspectives ultimately leading to the management of an envisioned unified management framework taking the recent advances from both worlds as a baseline. The book is intended to be a reference for control-oriented engineers who manage water systems with either or both purposes in mind (transport of water, transport of goods over water). It highlights the possible twofold nature of water projects, where water either acts as primary object of study or as a means. The book is dedicated to comparing and relating to one another different strategies for (operational) management and control of different but strongly related systems in the framework of the water. In that sense, the book presents different approaches treating both the transport of water and transport over water. It compares the different approaches within the same field, highlighting their distinguishing features and advantages according to selected qualitative indices, and demonstrates the interaction and cross-relations between both fields. It will also help to determine the gaps and common points for both fields towards the design of such a unifying framework, which is lacking in the literature. Additionally, the book looks at case studies where the design of modeling/control strategies of either transport of water or transport over water have been proposed, discussed or simulated.

This book is about the consequences of the Fukushima disaster in light of their technological, societal, political, cultural and environmental origins. The magnitude of the nuclear accident is investigated in this book in the contexts of politics, economy, and society. The authors scrutinize the relationships between science, technology and society leading to this accident. Further, the authors reveal how these relationships were constructed historically. This book provides a case analysis on the Fukushima disaster in political, societal, economic and cultural dimensions. In addition, analyses for historically grown relationships between different societal spheres mouthing into disasters are presented using examples of the Minamata disease (Mercury pollution), Itai-Itai Disease (Cadmium pollution), BSE, and GMOs. With this book, Yuko Fujigaki achieves to connect local and cultural peculiarities with generalized scientific information and practices in a coherent, logical fashion to a comprehensive volume on a very actual topic of global significance. In light of a globally increasing energy gap, this book has a distinct global relevance, providing an honest account on different triggers mouthing into the nuclear disaster. This book not only gives a scientific account. It also can also contribute to prevent future disasters starting from similar vectors.

Mohammed H Dore
R3,679 R1,680 Discovery Miles 16 800 Save R1,999 (54%) Ships in 12 - 17 work days

This book deals with the water policy and management in Canada. It discusses various problems and risks in the fresh and drinking water supply in the second largest country in the world. Mohammed Dore argues that water is underpriced and used wastefully in Canada. In selected case studies, he illustrates the major threats from human activity to Canadian freshwaters and drinking water resources, including manufacturing, mining, oil sands production, animal farming and agricultural use. Selected case studies include reviews of even dramatic incidences, e.g. the Walkerton tragedy of 2000, when 7 people were killed and 200 went onto permanent dialysis treatment because of water contamination with harmful pathogens. The book warns that wastewater treatment standards are often not sufficient, so that many drinking water resources are in peril of wastewater contamination. As most of the water resources are provincial responsibility, the book discusses the water management policies in the different provinces separately. Through a detailed discussion and statistical analyses, it can define water policy and management lessons that emerge from the investigated case studies. It ends by contrasting water policy and practice in Canada with the practice in some European countries.

Flow, Level and Pressure Measurement in the Water Industry (Hardcover): Graham Fowles Flow, Level and Pressure Measurement in the Water Industry (Hardcover)
Graham Fowles
R3,838 Discovery Miles 38 380 Ships in 12 - 17 work days

This is a definitive guide for engineers to the actual and developing practice in this important area, which is not only essential to those involved in water supply and sewage treatment but also important to those involved in any process industry where
fluid flow plays a part.

There are numerous benefits, including efficiency, cost saving and product quality, associated with the use of appropriate instrumentation in any industry. The advantages of effective measurement of flow, level and pressure in the water industry also include safety, hygiene and security of supply. Despite similarities with other process industries, the requirements of the water industry are unique in many ways. This book is the first to describe actual and developing practice in this exciting field for application of new instruments and techniques. Traditionally instrumentation used to measure water flows and levels was mechanical, but a new generation of electromechanical and electronic systems are now available. Much of the instrumentation described in this work is common to all process industries, though never before have operational and technical details used in the water industry have been described explicitly. Graham Fowles is Instrumentation, Control and Automation Controller at Severn Trent Water, UK. He has been an instrument engineer for 25 years, and has spent the last 20 years in the water industry. The measurement techniques and instruments he describes are applicable to all stages of the water cycle, including river monitoring, water supply, distribution and metering, and sewage treatment and disposal. The book is a definitive guide for water engineers which will also be of interest to any engineer concerned with fluid flow, such as in the petrochemical and food industries. - Control & Instrumentation, March 1994

Shlomo Nir, Uri Shuali
R4,675 R3,523 Discovery Miles 35 230 Save R1,152 (25%) Ships in 12 - 17 work days

This book focuses on water purification by micelle-clay nano-particles. The micelle-clay complex is composed of an organic cation (surfactant) with a long alkyl chain, e.g., ODTMA (octadecyltrimethylammonium) that spontaneously forms micelles of several nm in diameters at small concentrations. The positively charged micelles interact with a negatively charged clay (bentonite) at optimal ratios. The resulting complex has a large surface area per weight; it includes large hydrophobic parts and has an excess of a positive charge. The complex is insensitive to higher temperatures (50 0C), to pH values in the range of 2-11, or ionic strengths. Production of powdered and granulated complexes is described. The material characteristics of the micelle-clay complex differ from those of organo-clay of the same composition, which is formed by the interaction of monomers of the surfactant with the clay (Chapters One and Two). Model calculations enable simulations and predictions of removal of pollutants from water in batch or filtration experiments, and can yield cost estimates (Chapter Three). Laboratory and pilot experiments (Chapter Four) yield efficient removal from the water of (i) hydrophobic and anionic organic molecules: herbicides, humic acid, dissolved organic matter, and pharmaceuticals; (ii) inorganic anions, e.g., perchlorate; and (iii) microorganisms: bacteria, viruses, and parasites, e.g., cryptosporidium, which is resistant to chlorination. The (above) use of a micelle-clay complex indicated a big advantage in comparison with activated carbon. Low cost regeneration of used filters after bacteria adsorption is described. Biocidal effects of cations, e.g., ODTMA are demonstrated; released cations during filtration enhanced the filter efficiency. The released cations are removed from water before consumer use by another filter containing activated carbon. Drinking water from lakes is forbidden during cyanobacteria bloom due to harmful toxins. Filtration by the granulated micelle-clay complex and killing of cyanobacteria by ODTMA cations are described. Water purification by other clay-composites such as liposome- and polymer-clay is described in Chapter Five. Collaboration between technologies of water purification are found in Chapter Six: (i) Incubation of grey water in a moving bed biological reactor followed by filtration by the micelle-clay granulated complex enables water reuse at low cost. (ii) Filtration combined with degradation by solar photo-Fenton processes is a promising tertiary treatment of wastewater, including efficient removal of problematic pharmaceuticals. (iii) A new design of the micelle-clay complex may yield enhanced capacity for removal of microorganisms from water by combining filtration with biocidal action of free cations. This book describes inventions in material science and developments of computational procedures for simulations and predictions, and is an authoritative and stimulating reference for researchers, engineers and students involved in water treatment and adsorption processes.

Liquid Assets - Demographics, Water Management, and Freshwater Resources (Paperback): Jill Boberg Liquid Assets - Demographics, Water Management, and Freshwater Resources (Paperback)
Jill Boberg
R412 Discovery Miles 4 120 Ships in 12 - 17 work days

Most writings linking demographic trends to water availability often look only at population-growth effects, treating water supplies as static and population as increasing, inexorably leading to a water-availability crisis. This report's more holistic view of the interaction between demographics and water resources considers more demographic and local water-availability variables. It focuses on conditions in developing countries, where these factors intersect with the fewest socioeconomic resources to mediate.

High population growth, informal settlements, and organizational and financial mismanagement represent major challenges for the water supply in many cities in developing countries. This book contributes to solving those problems by identifying systematic shortcomings and proposing solutions to improve the financial conditions in two representative cities: Hyderabad and Varanasi. Serious improvements are necessary for the further development of the water supply and sanitation networks in these areas.

"Pricing Urban Water "offers a theoretical introduction to economics of the water sector, including the theory of water pricing and tariff systems, combined with detailed analyses of the water supply and sanitation infrastructure as well as of the municipal suppliers of Hyderabad and Varanasi. Introducing a method for estimating future water production costs in both cities serves as the basis for a tariff revision, which is put forward as one solution to improve the poor financial conditions both suppliers are in. Besides the revision of the tariff systems, some considerations on how to supply and charge urban poor and on the inclusion of private borewells in the tariffs are part of the discussion. Changes in both the organizational structure of the service providers and in the current delivery and use of the services are presented as further solutions to the problems in this sector.
