Carrier-Mediated Transport,selectively bind specific solutes present in the bathing solutions. The carrier provides an additional mechanism of transport through the membrane and, in so doing, generally accelerates the transport of specific permeants. Several modes are discussed—accelerated diffusion, coupled transport, and ex

,Transport Principles—Solution, Diffusion and Permeation in Polymer Membranes,ydrophobic and hydrophilic polymers are considered and interpreted in terms of hydrogen bonding to polymer sites and water clustering by hydrogen bonding. ., ., and . in non-uniform polymers are considered and discussed in terms of the effects of fillers, crystallites and layer structures.

FER

Gesture

Electrodialysis,and the economics of the process as well as the design of large-scale systems and operational problems are discussed. Examples for the use of electrodialysis in the food and drug industry and in advanced waste water treatment are given. Finally, recent developments and future prospects of electrodialysis and related processes are discussed.

Process Design and Optimization,n order to achieve the desired result. The last part of this chapter will deal with the application of membrane processes, the economics of membrane processes compared with conventional separation techniques and with hybrid processes, i.e., the combination of a membrane process and a conventional separation process such as distillation.

MOAT

Preparation of Asymmetric Membranes by the Phase Inversion Process, features of the membrane (skin, sponge structure, conical voids) are discussed in relation to the preparation procedure. It is shown that the skin layer is formed by gelation at increased polymer concentration, while liquid-liquid phase separation is responsible for the porous sublayer.
