Abstract

A deposit filtering apparatus and method for filtering turbid liquids. The apparatus is provided with an essentially cylindrical, vertical filter container, in which sieve-like plate-shaped filter elements are arranged vertically between the turbid liquid chamber and a filtrate chamber of the filter container. That side of the filter element facing the turbid liquid chamber is covered with a detachable filter membrane formed by depositing thereon a suspension agent aiding the filtering process. The turbid liquid chamber is connected to a turbid liquid conduit for supplying the turbid liquid, and the filtrate chamber is connected to a filtrate conduit for discharge of the filtered liquid. The bottom of the filter container has a closeable opening for removal of the filter cake, consisting of filtering aid agent and impurities, separated or detached from the filter elements. A filter element packet, which is closed on the four vertical sides thereof, is arranged as a removable unit in the filter container.
