“…Assuming that (Mehdizadeh and Dickson, 1989a) pressure is linear in [, then: It is interesting to note that the u2(p) and u3(p) are local Staverman (or reflection) coefficients at each side of the membrane. The larger the partial molar volume of the solute, v,, and/or the higher the operating pressure, AP, the larger is the pressureinduced transport of the solute.…”

“…In fact, none of the above have been able to predict the behavior that separation can decrease from positive to negative separation with increasing volume flux as is observed for solutes such as p-chlorophenol (Dickson et al, 1979;Dickson, 1985). A recent model for reverse osmosis transport, called the Modified Surface Force-Pore Flow (MD-SF-PF) model (Mehdizadeh and Dickson, 1989a), which reformulates and corrects the Surface Force-Pore Flow (SF-PF) model (Matsuura and Sourirajan, 1981), has been used successfully to describe and predict the usual phenomenon of solute exclusion from reverse osmosis membrane (Mehdizadeh andDickson, 1989b and1991). The MD-SF-PF model assumes the membrane to be microporous and models the pores as perfect right cylinders.…”

“…In this section, the extended MD-SF-PF model is derived in a manner paralleling the MD-SF-PF model (Mehdizadeh and Dickson, 1989a). First, the radial component of the solute flux and then the axial component of the solute flux together with the equation of continuity are examined.…”

Reverse osmosis is a highly effective separation technology used industrially in several areas, including desalination of seawater and brackish water and wastewater treatment. Membrane materials and types of modules used in reverse osmosis, as well as theoretical bases and operational aspects, are presented. A discussion of flux limiting conditions caused by concentration polarization and membrane fouling is included, as is that of the pretreatments required for process feed streams. The application of reverse osmosis for the separation of hazardous organic compounds from aqueous systems, for wastewater treatment, desalination, ultrapure water production, and food processing are reviewed in terms of membrane performance. The concept of nanofiltration and its applications are also discussed. General design considerations and economics are reviewed.
