摘要： Fine particles are separated from white water by the use of a disc filter, which comprises at least one rotating vertical filter disc (2), partly immersed in the white water to be separated, thereby sections (27) of the filter medium (5) of the filter disc are alternately displaced up from and down into the white water. When a section is displaced up from the white water it is covered by a cake containing fine particles which are detached in a detaching zone (16) before the section again is displaced down into the white water. According to the invention, each section is provided with a layer, solely containing fibres, in a forming zone (20) during each revolution and the section with its fibre layer is displaced through the white water in a separation zone (30), so that fine particles are deposited on the fibre layer and together with the latter form said cake.
摘要翻译：通过使用盘式过滤器将细颗粒与白水分离，所述盘式过滤器包括至少一个旋转的垂直过滤盘（2），其部分浸没在待分离的白水中，由此过滤介质（5）的部分（27）的过滤盘交替地向上或向下移动到白水中。当一个部分从白水上移开时，它被含有细颗粒的蛋糕覆盖，该蛋糕在分离区再次向下移动到白水中之前分离在分离区（16）中。根据本发明，每个部分在每个旋转期间在成形区域（20）中设置单独包含纤维的层，并且其纤维层的区段在分离区（30）中被移动通过白水，使得细颗粒沉积在纤维层上，并与后者形成所述饼。

摘要： A hydrocyclone plant comprises a great number of hydrocyclones (1) arranged in groups of at least two hydrocyclones, each group being made in one single piece. The hydrocyclones extend substantially radially in an annular inlet space (11) for a liquid mixture to be separated. The inlet space extends concentrically around a cylindrical heavy fraction space (10) for receiving a created heavy fraction of the liquid mixture from the hydrocyclones. According to the invention, the hydrocyclone groups are distributed around the cylindrical heavy fraction space in the circumferential direction of the latter and are spaced from one another in the inlet space to allow the liquid mixture to flow between adjacent hydrocyclone groups.
