Depth filtration is a process used to remove suspended solids from a liquid or gas. Unlike surface filtration, where solids are captured on the surface of a filter medium, depth filtration involves trapping particles within the tortuous pathways of the filter material itself. The filter medium is typically composed of a thick, porous matrix, such as a bed of sand, gravel, or specialized fibrous materials.
The effectiveness of depth filtration relies on a combination of physical mechanisms. These include inertial impaction,
Depth filters have a high dirt-holding capacity, meaning they can retain a significant amount of solid material
