Investigation and optimization of different types of draw solutes for forward osmosis water desalination

Abstract

The main aim of this study is to improve and develop different types of FO draw solutions with an easy recovery method for seawater desalination. The thesis comprises five chapters: Chapter I This includes introduction concerning the water crisis, general properties of the different types of water desalination methods, particularly FO and aim of this work was also involved. Great attention was given to the importance of FO application. Chapter II It comprises the literature survey on FO process, concerning its theoretical bases, general properties, literature survey of the draw solutes and FO different applications. Chapter III Chapter III describes the materials, reagents and instruments, the experimental methods are given concerning preparation of the draw solutes as well as types of analysis used to characterize this draw solute
