A new book from the American Society of Civil Engineers’ entitled Forward Osmosis: Fundamentals and Applications examines ways to easily and efficiently produce clean drinking water.
Forward Osmosis presents the principles and implementation challenges of low-energy desalination technology for producing potable and non-potable water. The book describes the basic concept of forward osmosis (FO) technology and discusses modelling and element design. The 518-page reference book is aimed at water and environmental engineering practitioners, environmental managers, government officials, and students.
Editors Ho Kyong Shon, Sherub Phuntsho, Tian C. Zhang and Rao Y. Surampalli explore different draw solutions and assess recently developed FO membranes.
In forward osmosis, a saline feed solution passes through a semipermeable membrane toward a draw solution; water then may be separated from the draw solution. Although FO technology has advanced in recent years, much work remains to be done to develop suitable membranes and draw solutions that can easily and efficiently produce drinking water.
Several different types of draw solution are explored and recently developed FO membranes are assessed. The book explores the physical, chemical, and biological aspects of membrane fouling as well as a variety of FO applications, including desalination, water reclamation, membrane bioreactors, mining wastewater, fertigation, and landfill leachate. Contributors also critically assess the limitations of specific FO technologies and suggest ways of overcoming these limitations. 518 pages, paperback.
