Lauded for its engaging, highly readable style, the best-selling first edition became the premier guide for nonengineers involved in water and wastewater treatment operations. Water and Wastewater Treatment: A Guide for the Nonengineering Professional, Second Edition continues to provide a simple, nonmathematical account of the unit processes used to treat both drinking water and wastewater.
Completely revised and expanded, this second edition adds new material on technological advances, regulatory requirements, and other current issues facing the water and wastewater industries. Using step-by-step, jargon-free language, the authors present all the basic unit processes involved in drinking water and wastewater treatment. They describe each unit process, the function of the process in water or wastewater treatment, and the basic equipment used in each process. They also explain how the processes fit together within a drinking water or wastewater treatment system and discuss the fundamental concepts that constitute water and wastewater treatment processes as a whole.
Avoiding mathematics, chemistry, and biology, the book includes numerous illustrations for easy comprehension of concepts and processes. It also contains chapter summaries and an extensive glossary of terms and abbreviations for quick reference.
Wetlands could be described as land and water at Tropical wetlands: one and the same time, and as such are very specific on the brink ecosystems. Their often rich variety of resources makes them highly valuable to the peoples who live With a few exceptions (like the Everglades in the or regularly stay in them. However, access to them United States), the last remaining large wetlands are to be found in developing countries. Perhaps this can is difficult and those unaware of their services be explained by insufficient financial resources, frequently associate wetlands with such nuisances and calamities as mosquitos, disease, floods, impen- lower popUlation density or a different concept of etrable wastelands, etc. As a result these areas are development and well-being. Whatever the reasons, often perceived as obstacles to human development many tropical wetlands still exist and support the and well-being. subsistence of many communities. But for how much History reflects these two views. Wetlands may longer? have been the cradle of great civilizations (like the During the last few decades tropical wetlands Maya, Inca, Aztec, Nilotic and Mesopotamian have also been destroyed or considerably altered. Dams and embankments now prevent water from civilizations), but elsewhere their destruction allowed other societies to develop. For example the Nether- spreading into the floodplains of several rivers, like lands literally 'emerged from the waters' thanks to the Senegal, Volta and Nile.
Water conflicts in India have now percolated to every level. They are aggravated by the relative paucity of frameworks, policies and mechanisms to govern the use of water resources. Based on the premise that understanding and documenting different types of water conflict cases in all their complexity would contribute to informed public debate and facilitate their resolution, Forum for Policy Dialogue on Water Conflicts in India, a collaborative initiative of the WWF project a Dialogue on Water, Food and Environmenta (TM), documented a number of such case studies.
One of its kind in India, this book brings together an impressive sixty-three case studies a " summarized status of the conflicts, the issues involved and their current position a " and gives us a glimpse into a the million revoltsa (TM) that are brewing around water. While recognizing that each conflict is a microcosm of wider conflicts, the editors have classified these cases into eight broad themes that try to capture the dominant aspect of the conflict. These are: contending water uses; dams and displacement; equity-access-allocations; micro-level conflicts; water quality; trans-boundary conflicts; privatization; sand excavation and mining.
With a mix of academics and activists as contributors, the book makes an important contribution to a new discourse on water in general, and water conflicts and conflict resolution in particular.
The consequences of a large dam failing can be disastrous. However, predicting the performance of concrete dams during earthquakes is one of the most complex and challenging problems in structural dynamics. Based on a nonlinear approach,Seismic Safety Evaluation of Concrete Dams allows engineers to build models that account for nonlinear phenomena such as vertical joint slippage, cracks, and cavitation. This yields more accurate estimates. Advanced but readable, this book is the culmination of the work carried out by Tsinghua University Research Group on Earthquake Resistance on Dams over the last two decades.
As the First International Conference on Water and Ions in Biological Systems (Bucharest, June 25-27, 1980) was appreciated as a success, a second one was organized in the fall of the year 1982 under the sponsorship of the United Nations Educational, Scientific and Cultural Organization (UNESCO), the Romanian Academy of Medical Sciences, the Romanian Biophysical Society (Union of Societies for Medical Sciences in the Socialist Republic of Romania) and in co- operation with the International Union for Pure and Applied Bio- physics (IUPAB). The responsibility for the scientific program and organization of the Second Conference on Water fell on an International Scientific Committee which included Prof. J. Tigyi (Pees), President of the UNESCO Expert Committee on Biophysics, Prof. K. Wuthrich, Secretary General of IUPAB and Prof. H. Eisenberg, (member of the IUPAB Council) under the guidance of an Executive Board whose members were Prof. J. Jaz (representative of UNESCO), Prof. B. Pullman (Vice- President of IUPAB) and Prof. V. Vasilescu (President of the Romanian Biophysical Society). The Meeting was attended by more than 250 specialists including 150 Romanian participants and others from Bulgaria, Czechoslovakia, England, the Federal Republic of Germany, the German Democratic Republic, Greece, Hungary, India, Israel, Italy, Japan, the Netherlands, Nigeria, Poland, Sweden, Switzerland, USSR, USA, Venezuela, Yugoslavia. The proceedings of the Conference took place in the Medical Faculty of Bucharest. The theoretical and practical importance of the Meeting was pointed out by the speakers, among whom were Prof.
