Desalination technologies help address the world's growing water scarcity problem. Desalination is the process of removing salt and other minerals from seawater and brackish water to make them useable for drinking, irrigation, industrial uses, etc. However, challenges associated with desalination processes persist, including high energy consumption, high costs, and environmental concerns such as brine disposal.

This book provides an overview of desalination technologies, their underlying principles and their process and system design and operation. The authors explore advancements in automation,  waste reduction, and other technological innovations in the field of water purification. Environmental impacts related to desalination are also discussed, including the resulting increase in seawater’s salt level, the impact of chemicals and brine discharge, and the contamination by the chemicals used in the process.
