Seawater Desalination Conventional and Renewable Energy Processes

A growing proportion of the world’s population is dependent on Seawater Desalination as a source of fresh water for both potable and civil use. One of the main drawbacks of conventional desalination technologies is the substantial energy requirement, whic

Foreword

The seas around us harbors over 97% of water in the world. Yet water stress and scarcity loom large as population grows. Desalination technology has come to harness the water treasure in the seas. Desalination plants growing in number, size and efficiency are supplying more and more water with lower energy requirements, more attention to environment and lower cost. At the same time, great efforts are being made to promote water conservation by more efficient use. Yet we have a long way to go. Lowering energy requirements and hence cost is the major challenge of desalination as it is for all energy consuming technologies. We now look to sun, wind and wave and we once looked to their Gods. If today we have not yet reached efficient ways to unlock this mighty source of energy and some skeptics lurk in the wings, research has even brought us to the moon. So it is essential to pursue research on solar energy coupled to desalination as well as wind and wave so
