Reverse Osmosis
The concepts of "osmosis" and "reverse osmosis" have been known for many years. In fact, studies on osmosis were carried out as early as 1748 by the French scientist Nollet, and many researchers investigated these phenomena over the next two centuries. However, the use of reverse osmosis (RO) as a feasible separation process is a relatively young technology. In fact, only in the late 1950's did the work of Reid show that cellulose acetate RO membranes were capable of separating salt from water, even though the water fluxes obtained were too small to be practical. Then, in the early 1960's, Loeb and Sourirajan developed a method for making asymmetric cellulose acetate membranes with relatively high water fluxes and separations, thus making RO separations both possible and practical.

RO Membrane Development
Since then, the development of new-generation membranes such as the thin-film, composite membrane that can tolerate wide pH ranges, higher temperatures, and harsh chemical environments and that have highly improved water flux and solute separation characteristics has resulted in many RO applications. In addition to the traditional seawater and brackish water desalination processes, RO membranes have found uses in wastewater treatment, production of ultrapure water, water softening, and food processing as well as many others. An estimate indicated that sales of RO membrane products had grown to $118 million yearly in 1990, with great potential for continued growth.

RO Membrane Characterization Techniques
Characterization of RO membranes is important since this allows insight into the relationship between membrane chemistry, structure, and transport properties. The most widely used characterization method is the measurement of water flux and solute rejection for the membrane; these can be easily measured and so give a quick indication of the suitability of a particular membrane for an application. However, fluxes provide only limited information about the characteristics and structure of the membrane and the role these play in water and solute transport. As a result, other characterization techniques are beginning to be employed in order to determine parameters such as pore size, barrier layer thickness, and membrane elemental composition.
