There are several types of filters and … Webthe type of the barrier, may be divided into (1) deep-bed filters and (2) surface-type filters. In the deep-bed filters, the mean pore size of filter media is bigger than the mean diameter of collected particles. The particles are deposited on the media through a combination of depth filtration mechanisms which are driven by various force fields.
