Filters are essential in industry and in everyday life to preserve machine functionality and for protection against toxic and allergenic substances. The demands on filter efficiency, selectivity, capacity, and filter lifetime increase constantly, and highly specialized solutions are needed for every filtration application. The traditional way of designing and testing filter prototypes is costly and time-consuming. This is due to the complex interplay of material properties of the filter media, arrangement of fibers in the medium, physical and chemical properties of the fluid being filtered, and characteristics of the particles in the fluid. A time- and cost-effective alternative to the trial-and-error method is the simulation of filtration processes.

The GeoDict filtration package has been developed for the simulation of filtration processes. It includes generators of 3D models of filter media, along with material property predictors to characterize fluid flow, particle movement, and particle deposition in the filter media, as well as filter clogging and cake filtration.

The GeoDict filtration package is the only off-the-shelf and easy to use software on the market that puts this functionality at your fingertips and runs on affordable computer hardware.
