The book under review attempts to address the important topic of new and emerging technologies for sustainable desalination. The water stress around the world with reasons like huge population growth, climate change and improper water management has led to the idea of augmenting water using desalination. Today several technologies have become proven and some are at proof of concept stage. Thermal systems like multi stage flash (MSF), multi effect distillation (MED) are well known and membrane systems like reverse osmosis (RO) are being used. These systems have known advantages and disadvantages and energy requirement continues to be an area of concern. However it is imperative to keep trying out new technologies because desalination is dependent on various factors like whether steam is available, whether water is brackish or seawater. The other concerns should be the operation and maintenance and sustainable utilization of the by products. Some of these issues are supposedly addressed in some of the chapters.
