DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention is a continuation-in-part of U.S. Patent Application No. 650251, filed February 4, 1991. The present invention relates to a manifold for a plurality of liquid filtration segments, wherein the feed manifold is positioned to promote efficient liquid flow through the system. More particularly, the present invention relates to a manifold system that includes a feed manifold positioned at an intermediate position within a manifold system comprising a plurality of stacked manifold segments.

[0002]

Prior to the present invention, liquids, especially aqueous liquids, have been filtered by tangential flow filtration modules. In this tangential flow filtration module, a plurality of filters are stacked between two manifolds, one at the bottom and the other at the top. The filtration module stack includes a collection of one or more filtration modules and an associated intermediate module gasket. The filters are separated by suitable screens and impermeable layers, thereby allowing the flow of filtrate and residue as well as liquid into and out of the filtration module stack.

[0003] In addition, flow holes are provided through the layers inside the filter module stack. These flow holes are suitably sealed to prevent pre-mixing of the filtrate with the incoming liquid or residue. The manifold of each manifold segment is designed so that filtrate is removed from both the top and bottom manifolds, while incoming liquid is introduced into one manifold and residues are removed from the other manifold. In such a manifold arrangement, for delivery to and removal from the manifold stack,
Fitting for both manifolds is required.
This is undesirable because it would require a new operating step to remove and install such fittings when attempting to replace the filtration elements that make up the manifold stack. Furthermore, the use of two manifolds to remove filtrate from the manifold stack increases the amount of filtrate retained inside the manifold stack undesirably. Of course, the use of two manifolds is undesirably expensive.

In US Pat. No. 4,849,102 it was proposed to provide a manifold for a plurality of filtration modules. However, the manifold arrangement is limited because only two filtration modules can be received while avoiding the use of conduits outside the manifold.
That is, if more than one filtration module is used, an external connecting conduit is required. US Patent Application No. 65
The manifold system described in No. 0251 includes a manifold for multiple tangential flow filtrations, where only one manifold is used, which requires any number of multiple filtration modules and conduits external to the manifold Receive without. This arrangement reduces the number of sealed fittings and reduces the equipment volume required to process a given volume compared to conventional systems. In this manifold system, the input is introduced from one end of the manifold stack, whereby the size of the input is limited by certain dimensions of the liquid flow path inside the manifold and compatible with such liquid flow. There must be.

SUMMARY OF THE INVENTION There is provided a manifold device including a plurality of manifold segments that can be in fluid communication with any number of a plurality of filtration modules without the need for conduits connecting the manifold segments outside the manifold segments. It is to be.

The feed manifold includes a feed inlet conduit that is larger than the feed conduit inside the manifold segment. The manifold system is designed so that the initial charge diverges into two sets of manifold segments on each side of the feed manifold.

[0007] All manifold segments, except the most downstream or most upstream manifold segment from the point where the liquid is introduced, should be provided with a filtrate outlet for filtrate exiting from both ends of the manifold segment. is there. The most downstream or most upstream manifold segment may also be provided with a filtrate outlet for filtrate from its outlet.
The feed manifold may also include an inner filtrate conduit.
The residue outlet may be provided at the feed manifold or at the end manifold segment. Filtrate from the filtration module coupled to the manifold segment is collected in the manifold segment and then recovered from a conduit in the feed manifold or from a filtrate outlet conduit from one or both ends of the manifold segment stack. Can be recovered.

[0008] The charge or fluid is in fluid communication with the residue within the manifold segment stack. The filtrate module is fixed to the manifold in such a way that the filtrate is separated and collected without premixing with the input or residue. The feed manifold includes a feed inlet,
Also, a residue outlet and / or filtrate outlet may be included. By using this delivery system, the delivery of an increased flow rate for a given internal fluid volume inside the manifold segment, as compared to introducing a delivery at each end position of the manifold segment stack. The object can be processed. This is because the incoming incoming fluid is branched off and sent inside the two sets of manifold segments separated by the feed manifold.
