Abstract

The combined ion exchange-membrane filtration system, whereby an active
filtration layer is formed using a slurry flow of resin beads and water,
has the potential to reduce energy usage and increase the quality of
purified wastewater. The hydrodynamic design of these systems is in its
infancy and there is a need for numerical methods to analyze such
systems. In this work, computational fluid dynamics coupled with the
discrete element method (CFD-DEM) is utilized to analyse the
hydrodynamics of the combined ion exchange-membrane filtration system,
and the formation of the filtrating bed and the parameters affecting it
are studied by varying the flow conditions. As a result, the details of
the bed formation with insights on the parameters affecting these
phenomena and suggestions for an improved hydrodynamic design of the
combined ion exchange-membrane filtration system are presented.
