Description
Even though most of the Earth's surface is covered withwater, most of it is not directly usable for human consumption orapplications. As the population increases and our general style ofliving standards increase, the importance useable water is becomingacute. This book addresses this issue with approaches to treatingwater sources that require removal of unwanted or dissolvedsubstances. In particular, it covers various methods for removingdissolved ionic materials. There are numerous methods foraccomplishing this end, and the book reviews most of them in somedepth.
