Abstract

The invention relates to a filtration device for deep-bed filtration which is easier to handle and enables filter modules(s) to be changed and disposed of easily. The filtration device has a casing with at least one filter module inserted in the casing with filter elements made from deep-bed filter materials stacked on top of each other. The filter elements have at least one internal structure formed by a perforation wherein the boundary surface of the perforation formed by the deep-bed filter materials creates a through-flow surface for filtrates or non-filtrates. At least one end plate has at least one inlet and/or outlet.
