The mass transfer coefficient can be calculated from the slope of the line obtained by plotting the solute concentration ratio (In [AC/AC ]) from Eq. (7) vs time. This iCjn is related to Eqs. (5) and (6). However, the parameters in the above Eqs. (5)-(7) are quite complicated functions. Hence, the gas absorption equations developed by Yang and Cussler [181] in hollow fiber contactors have been extended for liquid-liquid systems. The overall mass transfer resistance in hollow fiber modules is given by [2,182] ...

MBSS processes with closed loop of the solvent is shown in Figure 23.4. In this way recovery of the solvent and concentration of the solute can be achieved. Preferable contactors for MBSE and MBSS are hollow-fiber contactors, which are discussed in Chapter 2. Filling the pores with gel to protect against leakage of phase through the pores has been suggested in ref. [66],... 

A very interesting separation of biomolecules, for example, proteins and enzymes (BSA, lysozyme), in an aqueous two-phase system (ATPS) realized in hollow fiber contactor is suggested in the paper of Riedl and Raiser [72]. Application of ATPS in...

Membrane technology may become essential if zero-discharge mills become a requirement or legislation on water use becomes very restrictive. The type of membrane fractionation required varies according to the use that is to be made of the treated water. This issue is addressed in Chapter 35, which describes the apphcation of membrane processes in the pulp and paper industry for treatment of the effluent generated. Chapter 36 focuses on the apphcation of membrane bioreactors in wastewater treatment. Chapter 37 describes the apphcations of hollow fiber contactors in membrane-assisted solvent extraction for the recovery of metallic pollutants. The apphcations of membrane contactors in the treatment of gaseous waste streams are presented in Chapter 38. Chapter 39 deals with an important development in the strip dispersion technique for actinide recovery/metal separation. Chapter 40 focuses on electrically enhanced membrane separation and catalysis. Chapter 41 contains important case studies on the treatment of effluent in the leather industry. The case studies cover the work carried out at pilot plant level with membrane bioreactors and reverse osmosis. Development in nanofiltration and a case study on the recovery of impurity-free sodium thiocyanate in the acrylic industry are described in Chapter 42. 

As a part of our comprehensive programme on membrane technology, we evaluated nondispersive solvent extraction (NDSX) with a hydrophobic microporous hollow fiber contactor (HFC) for the separation and removal of actinides [1,10-12]. As the separation and recovery of actinides from different sources is paramount to radiotoxicity, there is a constant need for advances in the field. Among recently developed technologies, membrane extraction using microporous hollow fibers is particularly...

The strip process has been studied in hollow fiber contactors containing a woven fabric of fibers also by Wang and Cussler [49]. The modules (one rectangular and one cylindrical) contained baffles for increasing the mass transfer, but the rectangular one offered lower mass-transfer coefficients because of stagnant liquid zones between adjacent fibers.
