摘要： A membrane filter having one or more ducts is disclosed herein. Each of the ducts has a porous wall defining a lumen surrounded by helical grooves in the respective wall. The groove can be a single, double, or triple start groove defining a flow direction along the groove. The cross sectional area of the groove in the case of a single start groove, or aggregate cross sectional area of the groove in the case of a double or triple start groove, perpendicular to the flow direction along the lumen is within a range of 75% to 125% of the cross sectional area of the lumen. The helical grooves create vortices which reduce concentration polarization while increasing membrane area.
摘要翻译：本文公开了具有一个或多个管道的膜过滤器。每个管道具有限定在相应壁中被螺旋槽包围的管腔的多孔壁。凹槽可以是沿着凹槽限定流动方向的单个，双重或三个起始槽。在单个起始槽的情况下的槽的横截面面积，或者在沿着管腔的流动方向垂直的两个或三个起始槽的情况下的槽的集合横截面面积在75％到管腔横截面积的125％。螺旋槽产生涡流，其减小浓度偏振，同时增加膜面积。

摘要： An appliance for fragmenting heterogeneous elements of a fluid medium comprising a filter module with an inlet connected to a supply line for the fluid medium including heterogeneous elements and an outlet connected to a fluid medium outlet line. The filter module comprises a series of channels inside which the fluid medium is to be circulated. The appliance further comprises a planar fragmentation device which is located upstream of the inlet and comprises passages. In accordance with the invention, the planar device constitutes a screen comprising passages which have one dimension equal to the smallest dimension of the cross section of flow of the channels divided by n, where n is in the range 1.4 to 10. The passages are formed from cutting separator elements which define the passages and have a minimum thickness in the range 0.1 mm to 2 mm to ensure fragmentation of heterogeneous elements of the fluid medium.
摘要翻译：一种用于破碎流体介质的异质元件的装置，包括过滤器模块，其具有连接到用于流体介质的供应管线的入口，所述流体介质包括异质元件和连接到流体介质出口管线的出口。过滤器模块包括流体介质将在其中循环的一系列通道。该器具还包括位于入口上游并包括通道的平面破碎装置。根据本发明，平面装置构成一个屏幕，该屏幕包括通道的一个尺寸，其尺寸等于通道除以n的流动横截面的最小尺寸，其中n在1.4至10的范围内。形成通道来自限定通道的切割分离器元件，并且具有在0.1mm至2mm范围内的最小厚度，以确保流体介质的异质元件的碎裂。
