Filter Bed

A filter bed is a layer of loose or bonded material through which a liquid or gas is passed to remove solids or dissolved substances. Examples include sand filters, activated carbon beds, and ion exchange resins. The grain size, bed height, and packing density determine the performance of the filter bed.

In some applications, a filter bed is combined with a mesh fabric to stabilize the surface layer. GKD supplies mesh fabrics that serve as support structures for filter beds or are used as surface filters.
