More and more people are becoming aware of these environmental concerns and it is important that all individuals, many of whom do not possess an understanding of environmental problems or have the proper information available when involved with environmental issues, develop capabilities in this area. All professionals should have a basic understanding of the technical and scientific terms related to these issues. One of the key issues is water scarcity and the role desalination can play in improving global water security. Hopefully, this text will serve the needs of those interested in increasing their knowledge of, and help solve, the potable water problems facing society.
The current human population on Earth is approximately eight billion, and almost certainly will increase in the future. The influence and effects of human activities on the environment have become increasingly evident at the local, state, national, and international levels, while particular issues such as potable water availability and desalination have become more pervasive and pressing. The net result is that there has been a more significant increase in both awareness and interest about
