text_B: Depth filters are the variety of filters that use a porous filtration medium to retain particles throughout the medium , rather than just on the surface of the medium .. These filters are commonly used when the fluid to be filtered contains a high load of particles because , relative to other types of filters , they can retain a large mass of particles before becoming clogged .. fluid. fluid. Depth filtration typified by multiple porous layers with depth are used to capture the solid contaminants from the liquid phase .. Due to the tortuous and channel-like nature of the filtration medium , the particles are retained throughout the medium within its structure , as opposed to on the surface .. Depth filters pose the added advantage that they are able to attain a high quantity of particles without compromising the separation efficiency .. Depth filters are commonly characterised by the sand filter and have the ability to be used with substantially higher filter rates than in other designs .. filter. Filter ( chemistry ). It is these characteristics that have cemented the use and popularity of depth filters as an effective medium for separation .. With ongoing advances in process technologies depth filter designs are continuously adapting and improving to meet the needs of industry .. filter. Filter ( chemistry )
