Seawater And Desalting

Written by a select group of industry experts, under the supervision of the leading organization in water utilities, AWWA, this reference is the first practical guide to water desalination systems. Desalination is the process used to remove dissolved salts from seawater or highly-mineralized waters so that the water becomes usable for human and/or agricultural and industrial usage. This book offers authoritative guidance on the planning, design, and implementation of a successful water desalination system for public water utilities.

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.

Industrial desalination of sea and brackish water is becoming an essential part in providing sustainable sources of fresh water for a larger number of communities around the world. Desalination is a main source of fresh water in the Gulf countries, a number of the Caribbean and Mediterranean Islands, and several municipalities in a large number of countries. As the industry expands there is a pressing need to have a clear and well-written textbook that focuses on desalination fundamentals and other industrial aspects.This book focuses on the processes widely used in industry, which include multistage flash desalination and reverse osmosis. Also, other desalination processes with attractive features and high potential are featured. It includes a large number of solved examples, which are explained in simple and careful matter that allow the reader to follow and understand the development. The data used in the development of the examples and case studies are extracted from existing desalination plants.This title also includes comparisons of model predictions against results reported in literature as well as available experimental and industrial data. Several industries include similar unit operation processes, i.e., evaporators, condensers, flashing units, membrane separation, and chemical treatment. Examples of such industries include wastewater treatment, food, petroleum, petrochemical, power generation, and pulp and paper. Process fundamentals and design procedures of such unit processes follow the same procedures given in this textbook.

Increasingly, water-stressed cities are looking to the oceans to fix unreliable, contested and over-burdened water supply systems. Desalination technologies are, however, also becoming the focus of intense political disagreements about the sustainable and just provision of urban water. Through a series of cutting-edge case studies and multi-subject approaches, this book explores the political and ecological debates facing water desalination on a broad geographical scale.
