About this book
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.

Introduction
1.1 What Is Desalination?
Desalination is a process of separating and removing unwanted dissolved salts and minerals from feedwater sources such as seawater, brackish water, or wastewater.
The aim of desalination process is to produce a stream of fresh water (potable) with high quality (purity) according to the standards of World Health Organization (WHO), which state that the accepted maximum limit of total dissolved salts (TDS) in fresh water is 500 ppm (500 mg/l); if we take seawater (called feed or saline) as an example with a salinity of 35 000 ppm, feed can be desalted through two main industrial processes: (i) thermal desalination technologies where feed phase changes through evaporation and condensation processes and (ii) membrane desalination technologies where separation of salts achieved through using semipermeable membrane without feed phase change. In either process, potable water is produced, and salty water (called brine or concentrate) is rejected from desalination system; the rejected brine salinity varies in concentration based on technology, and it can reach up to 90 000 ppm.
Today, desalination industry plays a vital role in society development and economic growth, and worldwide freshwater consumption rate is approximately doubled every 20 years, where the availability of natural water sources is depleted. According to UN report and in the ...
