Desalination

Cogeneration of Electricity and Desalinated Water

Facilities that simultaneously produce electric energy and desalinated water from a single fuel source are known as cogeneration plants. The primary fuel input is used to produce high-temperature heat to generate electricity and low-temperature to distill seawater. Cascading the primary fuel energy through an integrated dual-purpose power/desalination plant is more fuel efficient than that of two standalone facilities. Further cost reductions are possible when the power and desalination facilities share operating and maintenance personnel. The objective of this book is to provide an in-depth understanding of the fundamentals, performance assessment, and economic evaluation of water desalination plants combined with power generation stations. The book contents are intended to be utilized by planners, professional engineers, and researchers being introduced or associated with desalination and power generation as well as by undergraduate and postgraduate university students.

Desalination of Seawater

The use of seawater desalination is an increasingly sought after alternative for new drinking water supplies in coastal areas, particularly as desalination becomes more economical. This new manual of practice parlays lessons learned from recent studies and global seawater desalination projects into guidance for desalination facilities that are reliable, economical, and environmentally sound. This new manual is specifically designed to help water utility managers and design engineers understand desalination–the technologies, the infrastructure, and the costs–to make informed decisions from planning through treatment plant construction. It explains environmental and ecological impacts of desalination plants, seawater intakes, and the disposal of concentrate discharges back into the ocean. Chapters describe the minerals and other constituents that determine source water quality and, therefore, treatment approaches.
