Preface
Distillationprocessesareatthecenterofnumerousmanufacturingfacil-
itiesspanningawiderangeofindustries.Commonapplicationsinclude
desalination, the manufacture of alcoholic beverages, fractionation of
organicliquids,waterremovalinpreparationforcrystallizationorspray
drying,andtheproductionoffruitjuiceconcentrates.Severaldifferent
types of industrial distillation processes are in use, the choice depend-
ingonprocessrequirements.Membranedistillation(MD)andosmotic
distillation (OD) are important additions to this range of processes as

modernmembraneseparationscience.Theadvantagesofferedbythese
emerging processes include unprecedented product quality and sub-
stantialenergysavings.
Accordingly, this book is intended to provide the reader with an
understanding of the theoretical and practical aspects of MD and
OD.Whiletheseprocesseshaveoverlappingareasofapplication,their
individualdevelopmentpathshavelargelybeendrivenbytheirdifferent
operational requirements. Historically, the main interest in MD has
arisen from growing desalination demands from a world in which 1
billion people are without safe drinking water. The main interest in
ODontheotherhandhascomefromthefoodindustryinresponseto
a growing consumer preference for high-quality liquid concentrates.
Fruit and vegetable juices with their delicate aromas and prevalence
of heat-sensitive vitamins and antioxidants have been at the forefront
of this interest. These factors have been reflected by a rapid increase
inthenumberofjournalarticlesandconferencepresentationsonMD
and OD in recent years. Indeed, MD and OD have been transformed
from laboratory novelties into processes that are now in the initial
stages of industrial implementation in applications long accepted as
