Depth filtration
Surface filtration is achieved by a filtering medium (generally very fine) the pores of which are essentially smaller than the size of the particles to be trapped. Thus solid particles are retained by direct
interception on the surface of the filtering medium. This filtration is very sensitive to preferential paths and can cause an
escape of solids when the filtering medium breaks.
On the other hand, in Filttex depth filtration the filtering medium is thicker and its pores are
smaller, equal to or greater than that of the particles to be retained. In this case, as well as direct interception, phenomena
of initial impact and/or diffuse interception occur that allow particles smaller than the pores in the filtering medium to be retained.
