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. This is due to:
- The complex interplay of material properties of the filter media.
- The arrangement and shape of fibers in the medium.
- The physical and chemical properties of the fluid being filtered.
- The characteristics of the particles in the fluid.
The traditional way of designing, building, and testing filter prototypes is costly in time and resources.
Simulations with GeoDict help filter media makers and filter manufacturers understand and productively improve existing filter materials. This approach not only leads to an efficient improvement of materials, but also to the development of completely new filter media and filters.
GeoDict covers the entire development workflow and supports you with extensive application-relevant functions.
You can, for example:
- Specify novel filter media characteristics and model filter media matching these specifications.
- Determine properties of filter media, such as grammage, largest through pore, multilayers, gradients, binder content, etc.
- Match computed properties to existing media by calibrating.
- Determine filtration properties of prototypic digital media, including initial pressure drop, single pass and multi pass filter efficiency, and filter capacity.
- Improve new filter media by varying thickness, fiber diameters, gradient and compression, etc.
Through computer simulations, new filter media, filter pleats, and filters with housing are engineered by honing in on a few promising designs and restricting costly lab tests to these few designs.
