<p>The invention relates to a method for treating flowable media, by means of which impurities are removed from the respective medium. Also disclosed is a device that is suitable for carrying out said method. The aim of the invention is to provide a solution which allows efficient filtering while making it possible to effectively and easily rinse the filter by switching to a backwashing mode. Said aim is achieved by the fact that the medium that is to be treated flows through at least one inclined filter reactor (6, 6') in order for particulate impurities to be removed, the filter (7, 7') of said at least one filter reactor (6, 6') being cleaned in a cyclic or acyclic manner by means of a backwashing operation that runs counter to the direction of flow during filtering. The medium penetrates the filter reactor (6, 6') from the bottom to the top during filtering while the rinsing medium is directed through the filter reactor (6, 6') from the top to the bottom in order to clean the filter (7, 7'). A granular filtering material which has a smaller density than the medium that is to be treated and forms a layered structure in the top area of the filter reactor (6, 6') during filtering is used as a filter (7, 7').</p> |
