Solar Distillation Practice for Water Desalination Systems


Book Description

This book essentially summarises the water shortage crisis in the world and its possible solution by using solar energy through solar stills. The world is facing an urgent problem. By 2015, 40 per cent of the world's population will be living in regions without adequate fresh water supply. Presently, almost all sea water desalination plans are electricity based and highly power intensive. With more than half the world likely to become dependent on sea water desalination such an energy-expensive scenario is clearly not sustainable.The aim of the book is to provide the most recent information on various practices, developments and improvements in water distillation, heat and mass transfer in solar distillation, thermal modelling and embedded energy of solar stills, and the applications of solar distillation in today's world. The concluding chapter also deals with economic analysis of solar distillation. To simplify the subject, figures, tables, solved examples and problems with hints are given at the end of each chapter, and there are appendices and a glossary of meaningful terms to assist the reader. The authors have written an outstanding academic work which carries weight and resonance beyond university courses and libraries, and which impacts on the global population.




Solar Desalination for the 21st Century


Book Description

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. It provides an up-to-date point-of-reference on the topic, giving an extensive overview of the current status of solar desalination, both from the research and industrial point of view.




Seawater Desalination


Book Description

A growing proportion of the world’s population is dependent on Seawater Desalination as a source of fresh water for both potable and civil use. One of the main drawbacks of conventional desalination technologies is the substantial energy requirement, which is facing cost increases in the global energy market. "Seawater Desalination" presents an overview of conventional and non-conventional technologies, with a particular focus on the coupling of renewable energies with desalination processes. The first section of this book presents, in a technical but reader-friendly way, an overview of currently-used desalination processes, from thermal to membrane processes, highlighting the relevant technical features, advantages and disadvantages, and development potential. It also gives a rapid insight into the economic aspects of fresh water production from seawater. The second section of the book presents novel processes which use Renewable Energies for fresh water production. From the first solar still evaporators, which artificially reproduced the natural cycle of water, technology has progressed to develop complex systems to harness energy from the sun, wind, tides, waves, etc. and then to use this energy to power conventional or novel desalination processes. Most of these processes are still at a preliminary stage of development, but some are already being cited as examples in remote areas, where they are proving to be valuable in solving the problems of water scarcity. A rapid growth in these technologies is foreseen in the coming years. This book provides a unique foundation, within the context of present and future sustainability, for professionals, technicians, managers, and private and public institutions operating in the area of fresh water supply.




Desalination and Water Treatment


Book Description

The need for fresh water is increasing with the rapid growth of the world's population. In countries and regions with available water resources, it is necessary to ensure the health and safety of the water supply. However, in countries and regions with limited freshwater resources, priority is given to water supply plans and projects, among which the desalination strategy stands out. In the desalination process, membrane and thermal processes are used to obtain fresh water from salty water that is in abundant amounts in the sea. This book will outline valuable scientific contributions to the new desalination and water treatment technologies to obtain high quality water with low negative environmental impacts and cost. The editors would like to record their sincere thanks to the authors for their contributions.

Introduction to Desalination


Book Description

One book dealing with the fundamentals of thermal and membrane desalination systems and discussing their economical as well as environmental aspects. With a growing population, climate change and greater water demand, desalination has increasingly become a part of the solution to regional water scarcity - seawater desalination capacity has roughly doubled in the past ten years. Desalination has also begun to receive more attention in academia, with research focusing on improving energy efficiency and system robustness and lowering capital costs. With this book, an introduction is given to the basics and fundamentals of desalination systems. Both, thermal and membrane desalination systems, are covered and discussed in view of energy, exergy, economic and environmental aspects. In the beginning, Introduction to Desalination: Systems, Processes and Environmental Impacts describes multi effect evaporation, vapor compression and multi-stage flashing. Further chapters deal with common membrane-based separations like reverse osmosis and membrane filtration, forward osmosis, diffusion dialysis and pervaporation as well as thermo-osmosis, electrodialysis and electrodeionization. Subsequently, hybrid systems are discussed, and the economic analysis of such systems and their environmental impact are highlighted. Each chapter contains theoretical and practical examples and concludes with questions and problems for self-study. * Needed: Desalination has become a part of the solution to regional water scarcity and an introductory book in this field is urgently needed. * Balanced Approach: Presents the fundamentals of thermal and membrane desalination systems. * Learning Material: Each chapter includes exercises for self-study and Instructors can find teaching material online. Introduction to Desalination: Systems, Processes and Environmental Impacts is an important resource for master's students in engineering sciences, lecturers in chemical and mechanical engineering, engineers, environmental chemists, as well as process engineers, engineering scientists in industry, and environmental consultants.




Fundamentals of Salt Water Desalination


Book Description

Industrial desalination of sea and brackish water is becoming an essential part in providing sustainable sources of fresh water for a larger number of communities around the world. Desalination is a main source of fresh water in the Gulf countries, a number of the Caribbean and Mediterranean Islands, and several municipalities in a large number of countries. As the industry expands there is a pressing need to have a clear and well-written textbook that focuses on desalination fundamentals and other industrial aspects.This book focuses on the processes widely used in industry, which include multistage flash desalination and reverse osmosis. Also, other desalination processes with attractive features and high potential are featured. It includes a large number of solved examples, which are explained in simple and careful matter that allow the reader to follow and understand the development. The data used in the development of the examples and case studies are extracted from existing desalination plants.This title also includes comparisons of model predictions against results reported in literature as well as available experimental and industrial data. Several industries include similar unit operation processes, i.e., evaporators, condensers, flashing units, membrane separation, and chemical treatment. Examples of such industries include wastewater treatment, food, petroleum, petrochemical, power generation, and pulp and paper. Process fundamentals and design procedures of such unit processes follow the same procedures given in this textbook.
