    • The invention concerns a method and a device for separation of separable constituents from a liquid medium. The separation device comprises only one cell or a stack of a plurality of adjacent cell, whereby each cell consists of a plate unit containing a filter, an inlet for supplying the liquid medium into a chamber, and outlet for discharging the reject and an outlet for discharging the permeate. The liquid medium is subjected to a strong turbulence created by a convenient designed rotor, possible combined with sound waves, whereby the deposition of separable constituents on the filter is prevented or essentially reduced. According to the invention a rotor is used in which the essentially plane surface of the rotor wings directed toward the filter comprises one or more areas deviating from the plane of said surface; or the surface of the rotor wings directed towards the filter is curved in such a way that the distance between the surface of the wing and the filer is small at the inner portion of the rotor and that said distance gradually increases towards the periphery of the rotor, or the section of the rotor wings in the plane parallel with the filter forms an almost S-shaped surface, whereby the S-shape is continuous.

    • A permeable membrane system comprised of at least two sheets, at least one of the two sheets being a grooved permeable membrane having regularly spaced grooves on at least one surface, the grooves having a predetermined spacing factor, the grooved permeable membrane either having essentially no barrier layer or having a barrier layer on one grooved surface, the sheets being positioned in a configuration with the grooves of that one grooved surface of the grooved permeable membrane sheet forming feed channels with a surface of another sheet which covers that one grooved surface, the grooves being about 0.5 to about 100 mils wide and deep and the feed channels being used to deliver the feed stream to the membrane surface. Preferably, both sheets are permeable membranes. The grooves in the sheets are preferably about 5 to about 35 mils wide and deep for reverse osmosis, about 0.5 to about 20 mils wide and deep for gas separation, and about 15 to about 75 mils wide and deep for ultrafiltration. The grooves on one side of one sheet may be aligned with the grooves on one side of an adjacent sheet, whereby the grooves on one side of one sheet form parts of the feed channels and the corresponding grooves on one side of the other sheet form the other parts of the feed channels. Or, the grooved sheets may be alternated with planar sheets so that the grooves on one side of the grooved sheets form the feed channels with the adjacent surface of a planar sheet.
    • 一种可渗透膜系统,包括至少两个片材,所述两个片材中的至少一个片材是沟槽可渗透膜,其在至少一个表面上具有规则间隔的凹槽,所述凹槽具有预定的间隔因子,所述带槽的渗透膜基本上不具有屏障 层或在一个沟槽表面上具有阻挡层,所述片被定位成具有沟槽的可渗透膜片的所述一个凹槽表面的槽的构造,其形成供给通道的另一片的表面覆盖所述一个凹槽表面,所述凹槽 约0.5至约100密耳宽和深,并且进料通道用于将进料流输送到膜表面。 优选地,两片都是可渗透膜。 片材中的凹槽优选为约5至约35密耳宽,深度为反渗透,宽度为约0.5至约20密耳,气体分离深度大,而用于超滤的宽度为约15至约75密耳。 一片的一侧上的槽可以与相邻片的一侧上的槽对准,由此一片的一侧上的槽形成供给通道的一部分,并且另一片的一侧的相应的槽形成 饲料渠道的其他部分。 或者,带槽的片材可以与平面片材交替,使得沟槽片材的一侧上的沟槽与平面片材的相邻表面形成馈送通道。

    • A system and method for enhancing the selective transport of fluid particles through a semipermeable membrane. The system consists of a conduit, comprising a semipermeable membrane, containing within it a plurality of sheet-like elements extending longitudinally within said conduit. Means are provided for flowing a first fluid through said conduit. Means are also provided, either for receiving the permeate passing through said semipermeable membrane or for submerging said semipermeable membrane in a second fluid. Each sheet-like element in the conduit is curved to turn the direction of fluid flow by being arranged in alternating right- and left-handed curvature groups (a group consisting of one or more elements). As a result, each particle of the fluid flowing through said conduit is moved in a programmed manner toward and away from the wall of the conduit. The semipermeable membrane selectively passes certain particles of at least one of the fluids. In one type of application, such passage tends to create a condition, commonly called ''''polarization,'''' in the fluid layer adjacent the inner wall of the conduit which decreases the rate at which the selected fluid particles pass through the semipermeable membrane. The action of the curved elements removes such layer from the inner wall, thus overcoming the inhibiting effect of such layer on the transport of the selected fluid particles through the membrane. In another type of application, in which a polarization layer is not formed, but in which it is desirable to distribute the fluid material adjacent such inner wall under non-turbulent conditions, the curved elements effectively produce the desired results without resorting to turbulent flow.
    • 一种用于增强流体颗粒通过半透膜的选择性输送的系统和方法。 该系统由包括半透膜的导管组成,其中包含多个在所述管道内纵向延伸的片状元件。 提供了用于使第一流体流过所述导管的装置。 还提供了用于接收通过所述半透膜的渗透物或将所述半透膜浸没在第二流体中的装置。 导管中的每个片状元件被弯曲以通过布置在交替的左右曲率组(由一个或多个元件组成的组)中来转动流体流动的方向。 结果,流过所述导管的流体的每个颗粒以编程的方式移动并且远离导管的壁。 半透膜选择性地通过至少一种流体的某些颗粒。 在一种类型的应用中,这种通道倾向于在邻近管道内壁的流体层中产生通常称为“极化”的状态,这降低了所选择的流体颗粒通过半透膜的速率。 弯曲元件的作用从内壁去除这样的层,从而克服了这种层对所选择的流体颗粒通过膜的输送的抑制作用。 在另一种类型的应用中,其中没有形成偏振层,但是在非湍流条件下希望将流体材料分布在这种内壁附近,所以弯曲元件有效地产生期望的结果而不求助于湍流。
