Sustainable Materials and Systems for Water Desalination

Abstract

Dwindling water quality has become a global matter of concern due to the overgrowing expansion of industrial/agricultural activities and climate change that threatens to cause significant alterations to the hydrological cycle. There is an urgent need to treat water from unconventional sources due to the increase in the pollution levels and a decrease in groundwater availability. Membrane desalination technology has gained tremendous importance in the recent past owing to its exceptional capability of water treatment. The electrodialysis (ED) is one of the promising membrane desalination technologies, thanks to its wide range of applications, the flexibility of operation, and robustness. The present chapter covers the essential aspects of the desalination process carried out using ED technology. The chapter highlights the history of ED development, the principle of operation, different parts of ED cell, and preparation of dimensionally stable anode. It also highlights the principle of operation and the concept of reverse electrodialysis (RED) while considering challenges and opportunities in the field.
