ABSTRACT

Membrane processes are now commonplace in the dairy, food, chemical, pharmaceutical, and water-treatment industries. Successful design of a membrane process relies on the ability to predict filtration performance; for these predictions, the modelling of mass-transfer processes is essential. After a brief introduction to the fundamentals of membranes and membrane processes, modelling of pressure-driven membrane processes will be discussed in detail. Section 5.2 will review the currently available models and Section 5.3 is a case study on the prediction of permeate flux in ultrafiltration using computational fluid dynamics.
