Abstract
The invention relates to an improved separation device in which a plate unit containing the filter comprises a separate abutment ring and a cassette which can be easily connected thereto, said cassette comprising at least one filter together with, if required, a frame belonging thereto so as to support the filter. If the filter consists of a flexible membrane, this is fitted into a special frame. However, if the filter is a rigid self-supporting filter of a porous material, for example, a ceramic filter or the like, a separate frame is not needed to support the filter.
