Roadmap for the Development of Desalination Powered by Renewable Energy


Book Description

The world water crisis is one of the largest public health issues of our time. One in eight people (884 million people) lack access to safe drinking water. The lack of clean, safe drinking water is estimated to kill almost 4,000 children per day. Many regions of the world are increasingly turning to desalination of brackish and sea water in their effort to match the increasing demand with the available natural resources. The trend is intensified by climate change, which seems to be already affecting the water cycle resulting in long periods of drought. The desalination industry has responded well to the increasing demand and is constantly evolving by reducing the costs and reliably producing water of very high quality. Most innovations focus on reducing the energy demand, since this is associated with high operating costs. However, desalination processes will always require considerable amounts of energy. If conventional energy sources are used, they contribute to climate change, which, in turn, affects the water cycle and intensifies the original problem that desalination was intending to solve. For desalination to remain a viable option in a world with a changing climate, renewable energy sources have to be used to meet at least part of its power requirements. The scientific community has been working for decades on optimising technological combinations where the desalination process is powered directly by renewable sources; thermal energy, electricity or shaft power. The industry is also recognising the potential and various companies are active in this field. The Roadmap ist the main outcome of the ProDes -Promotion of Renewable Energy for water production through desalination. It has been developed with input from various key actors from the industry and academia. This roadmap is intended to assist in coordinating and guiding the renewable energy-desalination community in overcoming the barriers they are currently facing.

A Multidisciplinary Introduction to Desalination


Book Description

Although more than 70% of the globe is covered with water, only a small portion is suitable for direct human use, making the scarcity of freshwater one of our plant's most serious challenges. In this context "desalination", defined as "the removal of salt from water", is one of the possible solutions for overcoming our planet's municipal and industrial thirst. By drawing upon the authoritative expertise of a remarkable team of international authors, this book aims to provide an encompassing and "multidisciplinary" introduction to various aspects of desalination. The forte of this publication is that it does not overtly focus on a particular sub-topic of desalination, but rather addresses the topic as a whole. In other words, the unique assortment of reader-friendly chapters is designed to strike a delicate balance between the technical and non-technical. The book is divided into five general sections:The first section presents an overview of water scarcity, followed by a review of integrated water management and the alternatives to desalination. The fundamentals of desalination are provided, including simple water chemistry;The second section covers the conventional technologies of today, including thermal and membrane desalination processes. The topics of pre- and post- treatment are given due credit, as no desalination plant can operate without them;The third section reviews the history of how desalination technologies originated, including a review of today's R&D activities and cutting edge research. The processes and engineering applied for membrane manufacturing are also presented;Section four is concerned with energy and environmental issues, including the application of renewable and nuclear energy, minimization of energy usage and the water-energy-nexus, brine management, and environmental impacts;Finally, section five covers the social and commercial issues, ranging from rural desalination, to the politics of desalination. Desalination costs and feasibility are presented, as well as issues in business development and the future market prospects.Effectively, A Multidisciplinary Introduction to Desalination aims to be a holistic go-to-compendium for anyone seeking a balanced understanding of the various facets of desalination

Renewable Energy Applications for Freshwater Production


Book Description

Worldwide, many regions have a great potential to cover part of their pressing water needs by renewable energy powered water treatment processes using either thermal or membrane based technologies. Not only arid and semiarid regions are increasingly suffering from water shortage but also many other regions face a limitation of freshwater resources either by increasing contamination of surface water bodies or groundwater resources unsuitable for drinking and irrigation purposes either due to their high grade of mineralization or their contents of toxic components. In many areas without centralized water supply, treatment techniques using locally available renewable energy resources such as wind, solar and geothermal can provide an economical, social and environmentally sustainable option for clean water production from seawater and from highly mineralized or otherwise unsuitable ground- and surface water. This book provides an overview on possible cost-efficient techniques and application opportunities for different scales and shows why the implementation of these technologies faces numerous technological, economic and policy barriers and provides suggestions how they can be overcome. It serves as a synoptic compendium of the fundamentals of freshwater production using renewable energies, applicable to all types of water, ranging from brackish to marine water and also including industrial and communal residual water. The book is aimed at professionals, academics and decision makers worldwide, working in the areas of water resources, water supply,land planning, energy planning, greenhouse gases emission mitigation and rural development.
