Modeling of batch and semi-batch membrane filtration processes
journal contribution
posted on 2015-09-14, 09:07 authored by Z. Kovacs, Marco DiscacciatiMarco Discacciati, W. SamhaberA mathematical frame for modeling batch and semi-batch membrane filtration processes is provided. The
approach followed in this work uses the feed concentrations as a basis for the calculations, rather than the
concentration factor. A practical computational algorithm is proposed. Our method hands separately the
design equations describing the engineering aspects of batch and semi-batch systems and the models of
mass transfer through the membrane. Thus, different methods can be applied to compute the permeate
flux and rejection without having to modify the general framework. In particular, we present an empirical
approach to characterize the membrane separation behavior based on a minimal number of experiments.
Moreover, we consider irreversible thermodynamics models and a transport model based on the extended
Nernst–Planck equations. Finally, various batch and semi-batch nanofiltration operations are carried out
with an organic/electrolyte binary test solution to validate the proposed algorithms.
