摘要： The invention concerns a continuous vacuum filtering apparatus, with endless belt, for example for filtering, drying and desiccating wastewater sludge in sedimentation tanks or industrial treatment plants, comprising a filtering support or medium (4) arranged in the form of an endless belt wound on two rotating cylinders (2, 3) one of which is coupled with a motor (5) driving it in rotation, the filtering support or medium upper side (4') being arranged between a hopper (9) receiving products to be filtered provided outside the loop constituted by the endless belt and a vacuum vessel (7) provided inside said loop. The invention is characterised in that the filtering support or medium (4) consists of two superposed cloths (4A, 4B) made integral with each other, i.e. an external filtering cloth (4A) and an internal cloth (4B), the internal cloth (4B) meshwork being larger than the external filtering cloth (4A) meshwork.

摘要： System (10) for separating solids from slurry (12) from a source (14). The slurry (12) is flowed into a separation channel (20) positioned over a moving foraminous medium (26) to effect cross flow separation of liquid from the slurry (12) in an initial channel section (21) followed by separation of solids from the slurry (12) in a second channel section (23), all the separation being effected employing the moving foraminous medium (26). The flow rate of slurry (12), the rate of travel of the foraminous medium (26), and the differential pressure across the foraminous medium (26), as established by the pressure exerted by the flowing slurry on the foraminous medium (26) and the relative pressure underneath the foraminous medium (26), are controlled in different compartments (34a-34d) underneath the length of the separation channel (20) to provide optimum steady state separation.
摘要翻译：用于从浆料（12）与源（14）分离固体的系统（10）。浆料（12）流入位于移动的有孔介质（26）上方的分离通道（20），以在初始通道部分（21）中实现液体从浆液（12）的交叉流分离，随后将固体从所述浆料（12）在第二通道部分（23）中，所有的分离都使用移动的多孔介质（26）进行。浆料（12）的流速，多孔介质（26）的行进速率以及多孔介质（26）上的压力差是由流浆在多孔介质（26）上施加的压力所确定的，并且在多孔介质（26）下方的相对压力被控制在分离通道（20）的长度下方的不同隔室（34a-34d）中，以提供最佳的稳态分离。
