A Desalination Primer
Two foremost expert have joined to write this introductory book for newcomers to the field of desalination and for students of this technology As a result of the development of arid regions and also in the wake of intensive use of water in urban areas all over the world, fresh water is frequently not available in the quantities desired. In the last four decades great strides have been made in the science and technology of water desalination. In 1993 more than 15 million cubic meters (4 billion gallons per day of fresh water were produced by the desalination industry. Statesmen, economists, scientists and engineers must often make decisions relating to this field. Quite often such decisions involve the disposition of considerable amounts of energy and investment funds. It is hoped that this book will provide newcomers with sufficient background to appreciate the fundamentals involved, to understand the jargon of the "insiders" to guide them to the rich original multidisciplinary literature of this field, and to facilitate the first stages of further reading and study..

Solar Desalination for the 21st Century: A Review of Modern Technologies and Researches on Desalination Coupled to Renewable Energies (NATO Science for ... Security Series C: Environmental Security)
Water scarcity affects the African, Asian, European and American continents, causing serious problems of social welfare and stability. This book of the NATO Science Series presents the state of the art of Desalination Technologies driven by Renewable Energies, highlighting the results achieved in the research field and presenting the potentialities of such technologies. Following an Advanced Research Workshop held in Tunisia from the 23rd to the 25th of February 2006 and collecting prominent scientists from more than 20 different countries, several contributions were selected from researchers, technicians, and industrial representatives, each focused on several different aspects of the use of renewable energies for desalination. Moreover, several regional overviews illustrate the actual state of RE exploitation in most of the countries interested by water scarcity and abundant availability of solar, wind and other renewable energies. .

Desalination: A National Perspective
There has been an exponential increase in desalination capacity both globally and nationally since 1960, fueled in part by growing concern for local water scarcity and made possible to a great extent by a major federal investment for desalination research and development. Traditional sources of supply are increasingly expensive, unavailable, or controversial, but desalination technology offers the potential to substantially reduce water scarcity by converting the almost inexhaustible supply of seawater and the apparently vast quantities of brackish groundwater into new sources of freshwater."Desalination" assesses the state of the art in relevant desalination technologies, and factors such as cost and implementation challenges. It also describes reasonable long-term goals for advancing desalination technology, posits recommendations for action and research, estimates the funding necessary to support the proposed research agenda, and identifies appropriate roles for governmental and nongovernmental entities..

Seawater Desalination: Impacts of Brine and Chemical Discharge on the Marine Environment
Population growth, ongoing industrialization, land irrigation and higher living standards increase the demand for drinking water. Ground waters are already excessively exploited and at risk of salt water intrusion in coastal areas, while surface waters are scarce or polluted. As good quality raw water becomes less available, water must be purified and augmented by seawater desalination. An introduction to the two main desalting processes is given in this book with an emphasis on vulnerable points in process design and choice of materials. To protect reverse osmosis and multi-stage flash plants from certain types of seawater constituents, chemical pretreatment is required, while cleaning chemicals are used to restore the plants’ efficiency. Both procedures are described with regards to the type of foulant. Classification into different groups of chemicals is made, and single chemicals and underlying mechanisms that make them effective additives are described. This book appeals for environmental assessments of new desalination plants and it is the first which provides data about the chemical discharges into the sea and their marine ecological effects. Special attention is given to the Arabian Gulf where 50% of worldwide seawater plants operate. This approach takes the Gulf’s high installed capacity into account and relates it to the surrounding Gulf ecosystem. Maps of the region are included and an outlook for the future presented..

Seawater bitterns as a source of liquid desiccant for use in solar-cooled greenhouses [An article from: Desalination]
This digital document is a journal article from Desalination, published by Elsevier in 2006. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser. Description: The processes of desalination and sea-salt production currently produce large quantities of by-product, in the form of brine and bitterns, which is generally regarded as waste. This article explores the scope for exploiting the hygroscopic salts occurring in these by-products - such as magnesium, calcium and sodium chloride - as desiccant solutions in a greenhouse cooling system. These solutions are compared to other liquid desiccants more conventionally used in solar-driven refrigeration: namely solutions of lithium chloride, lithium bromide and zinc chloride. To establish which properties are relevant, we discuss the relation of the properties of the liquid desiccant to the attributes of the greenhouse as a whole. A property of primary importance is hygroscopicity, as quantified by the equilibrium relative humidity (ERH). Further properties reviewed include cost, availability, density, viscosity, specific heat capacity, thermal conductivity, heat of dilution, water absorption capacity, human- and ecotoxicity, and corrosivity. Calculations based on five locations (Tunis, Jiddah, Abu Dhabi, Mumbai and Bangkok) show that the liquid desiccant should have ERH @?50% to give improved cooling compared to both direct and indirect evaporative systems. Except for sodium chloride, all six salts considered meet this requirement. Magnesium chloride is the most abundant salt in seawater bitterns and both magnesium and calcium chloride stand out as being of low toxicity. Their hygroscopic properties, though inferior to those of the lithium and zinc salts, make them suitable for cooling of greenhouses (even if not of human dwellings). We envisage an integrated desalination and agricultural system, comprising a solar desalination plant supplying freshwater (for irrigation) and bitterns (for cooling) to greenhouses, enabling efficient water use and local crop production in hot climates. .
