  • Publication number: 20050173318
    Abstract: A device for cross-flow filtration includes a plurality of linear filtration modules arranged parallel to each other and branching from a manifold arranged such that a flow transverse to the front surface of the filtration module is generated in front of all filtration modules. A constant flow velocity transverse to the front faces of the filtration modules is achieved by reducing the open cross-section of the manifold in the direction of flow, the reduction being continuous or stepwise. By avoiding the build-up of fibrous clumps, the fault-free operating time of filtration device can be significantly lengthened with relation to a conventionally embodied filtration device.

  • Patent number: 6530315
    Abstract: In a diaphragm (3) of a diaphragm press for separating liquid and solid materials by action of a pressure medium on the materials (7) via the diaphragm (3), the functions of sealing and retention are separated. This is accomplished by a dual embodiment of the diaphragm (3) in the form of a substantially sealing diaphragm seal (14) and a substantially retaining diaphragm carrier (13). A force transmission from drainage elements (6) in the press chamber (4) of a pressing vessel (1) of the diaphragm press to the diaphragm (3) can be accomplished by the diaphragm carrier (13) in a manner that treats the material gently. This substantially improves the service life of the diaphragm (3).

  • Patent number: 6495046
    Abstract: The method relates to bringing about a mixed state of at least two fluids in a second part (34) of a line, which have flowed through a first part (32) of this line. This is attained in that a fractional flow of the fluids is withdrawn from the second part (34) of the line at a point (43), and this fractional flow is resupplied to the second part (34) of the line at a different point (45). A employment to avoid clogs in modules in a crossflow filtration system is described, along with apparatuses for performing the employment.

  • Patent number: 6375847
    Abstract: The method relates to the operation of a cross-flow filtration installation for a product. This installation includes a filtration module (6), a pipeline (3) for the inflow of the product, a pipeline (9) for removing the product, a pump (4) with an electric motor (12) for recirculating the product, and a control valve (5′) for setting the conveying flow (Q1) of the pump (4). In order to make possible the maximally possible filtration output, based on the installation, along with a high proportion of solids of the product, without endangering operational safety by means of overloads, the strength of the operating current (i1) of the electric motor (12) is measured. The operating current (i1) is adjusted to a maximally, permissible value via a regulator (20) by setting the conveying flow (Q1) of the pump (4) by adjusting the flow control valve (5′).

  • Patent number: 6113791
    Abstract: The process for flushing filtration modules of a cross flow filtration device is carried out in a unit that is used for the clarification of liquids in a retentate circulation circuit. When the unit is shut down, for example as the result of a power failure, filtration modules are flushed free of solid particles by the supply of an addition of flushing agent that increases over time and/or geometrically into the retentate side of the cross flow filtration device. As a result, the danger of clogging of the filtration modules is largely avoided.

  • Patent number: 5958244
    Abstract: For thickening a retentate by means of membrane filtration (ultra-/micro-filtration) to obtain the highest possible wet sludge proportion, a gaseous medium is admixed with the retentate. To this end an open feed line (13) above the retentate level (14), a porous ring (17) in the retentate, or a simple line connection (19, 20, 28, 29) in a tank (6) are proposed. A number of advantages accrue as a result of the lowering of the viscosity of the retentate achieved in this way, such as savings of energy for retentate recirculation, efficient installations because of longer series or passes of filtration modules, and savings in squeezing installations because of the direct filtration with high solid components.

  • Patent number: 5800713
    Abstract: To thicken remaining residues in ultrafiltration or microfiltration for clarifying fruit juices, systems having membrane module groups (1, 2, 3) connected in series are used in the cross flow process with a residue circuit. The groups (1, 2, 3) can be individually switched on or off in succession, depending upon the present thickening gradient of the residue in the residue feed stream. By operating a suitable number of groups (1, 2, 3), an operationally favorable working pressure is kept constant at the membrane modules until as great as possible a desired value of the thickening gradient of the residue is reached. In this way, an improvement of the overall capacity of filtration systems is achieved.
