摘要： A stacked membrane disk module has a number of membrane disks interleaved with seal rings and includes a biasing subassembly for maintaining a compressive force between the membrane disks and interleaved seal rings so that the module can be repeatedly pressurized/depressurized. The membrane disks preferably include a central first aperture and a pair of second apertures which are radially spaced from the central first aperture. These apertures will thus be respectively registered when a number of such membrane disks are stacked between a pair of end plates so as to establish a central fluid passageway and a pair of second fluid passageways. A rigid perforated tube is positioned within the central fluid aperture and is connected to the end plates so that at least one of the end plates is capable of being axially displaced relative to the perforated tube. A biasing member (e.g., a compression spring, stack of truncated conically shaped washers or the like) may thus be concentrically positioned around the perforated tube so as to exert a bias force onto one of the end plates capable of axial displacements and thereby cause a compressive force to be exerted against the membrane disks in the stack.
摘要翻译：堆叠的膜片模块具有多个与密封环交错的膜盘，并且包括用于保持膜盘和交错密封环之间的压缩力的偏置子组件，使得模块可以被反复加压/减压。膜盘优选地包括中心第一孔和与中心第一孔径向间隔开的一对第二孔。因此，当在一对端板之间堆叠多个这样的膜盘时，分别注册这些孔，以便建立中心流体通道和一对第二流体通道。刚性穿孔管定位在中心流体孔内并且连接到端板，使得至少一个端板能够相对于穿孔管轴向移位。因此，偏置构件（例如，压缩弹簧，截顶圆锥形垫圈等的堆叠）可以同心地定位在穿孔管周围，以便对能够轴向位移的一个端板施加偏压力，从而导致对堆叠中的膜盘施加的压缩力。

摘要： Membrane disk assemblies include membrane disks which have feed and residue apertures formed through and bounded entirely by a perimetrical edge region of the disk. Preferably, the feed and residue apertures are formed though a fluid-impermeable support rim positioned in the perimetrical edge region of the membrane disk which serves to sealably bond the exterior membrane sheets and at least one interposed permeate carrier sheet one to another. Most preferably, the support rim includes inwardly directed lobes through which the feed and residue apertures are formed. The membrane disks will also include a central permeate aperture in fluid communication with the carrier sheet interposed between the pair of membrane sheets. When a number of such membrane disks are assembled in stacked relationship with the feed, residue and central permeate apertures registered, there will be formed respective feed, residue and permeate passageways through the stack. In order to create the desired flow of fluid through the stack of membrane disks and across the active surfaces of the membrane sheets, annular high and low pressure seals are interposed concentrically between adjacent membrane disks in the stack. In addition to providing necessary sealing functions, the high and low pressure seals define a slight, but significant, clearance space between immediately adjacent membrane sheets of membrane disks in the stack to allow for fluid flow between the feed and residue apertures.
