A depth filter is a type of filter that captures and removes filtrate not from the surface of the filter, but from the inside.
The reason for the internal trapping is that the filter is designed so that the pore diameter is larger at the top of the filter and gets smaller as it gets closer to the bottom.
On the other hand, the type of filter that intercepts on the surface is called a screen filter and is widely used.
Screen filters have the disadvantage that filtrate accumulates on the surface, gradually clogging the filter and reducing the flux.
A depth filter, on the other hand, prevent clogging and maintain a high filtration rate.
Depth filters are used for purification, concentration, and removal of bacteria and foreign matter in various industries such as the chemical, food, and pharmaceutical industries.
Although the filters themselves are also used in the home in areas such as water purification, depth filters are typically used for pretreatment in industrial applications. Normally, when filtering to remove objects or foreign matter, multiple filtration is performed using filters with different pore diameters. This is one of the ways to minimize clogging.
Depth filters are used in the initial stage of filtration because of their coarse and large pore size.
Depth filters are characterized by their inability to remove completely depending on the type used. Recently, there are filters that use glass fiber and cellulose fiber as materials, but since they are only pressed together, foreign matter can penetrate if the thickness and density adjustment is insufficient. If foreign matter is to be reliably blocked, depth filters with a gradient in pore diameter should be used.
