Description

Detailed Description of the Invention

[0001]

This invention is a continuation-in-part application of U.S. patent application Ser. No. 650,251 dated February 4, 1991. The present invention relates to a manifold for a plurality of liquid filtration segments, wherein the feed manifold is positioned to facilitate efficient liquid flow through the system. More particularly, the present invention relates to a manifold system including a feed manifold positioned at an intermediate position within a manifold system consisting 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, multiple filters are stacked between two manifolds, with one located at the bottom and the other at the top. A filtration module stack includes one or more filtration modules and associated intermediate module gasket assemblies. The filter is separated by a suitable screen and impermeable layer, which allows the flow of filtrate and debris as well as liquid into and out of the filtration module stack.

In addition, flow holes are provided through the layers inside the filtration module stack. These flow holes are suitably sealed to prevent premixing of the filtrate with the influent liquid or residue. The manifolds of each manifold segment are designed so that filtrate is removed from both the top and bottom manifolds, while incoming liquid is introduced into one manifold and debris is removed from the other manifold. In such a manifold arrangement, for delivery to and removal from the manifold stack,
Fittings for both manifolds are required.
This is undesirable as it requires additional operating steps to remove and install such fittings when attempting to replace the filtration elements that make up the manifold stack. Moreover, the use of two manifolds to remove filtrate from the manifold stack undesirably increases the amount of filtrate retained inside the manifold stack. Nevertheless, 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 by the fact that only two filtration modules can be received while avoiding the use of conduits outside the manifold.
That is, an external connecting conduit is required if more than one filtration module is used. US Patent Application No. 65
The manifold system described in 0251 includes multiple manifolds for tangential flow filtration, where only one manifold is used, which requires any number of multiple filtration modules and conduits outside the manifold. To collect without. This arrangement reduces the number of sealed fittings and reduces the equipment volume required to process a given volume as compared to conventional systems. In this manifold system, the feed is introduced from one end of the manifold stack, which limits the size of the feed by the constant size of the liquid flow path inside the manifold and is compatible with such liquid flow paths. There must be.

SUMMARY OF THE INVENTION In accordance with the present invention, a manifold system is provided that includes a plurality of manifold segments. The manifold device can be in fluid communication with any number of multiple filtration modules without the need for conduits connecting the manifold segments outside the manifold segments. A manifold arrangement according to the present invention includes a plurality of manifold segments, which are interconnected to form a stack of manifold segments, with a feed manifold positioned at an intermediate position inside the stack of manifold segments. The manifold segment comprises a single member carrying a filtration module on each side thereof and also comprises inner conduits for feed, filtrate and debris. The feed manifold includes a larger feed inlet conduit than the feed conduit inside the manifold segment. The manifold system is designed so that the initial feed diverges into two sets of manifold segments on each side of the feed manifold.

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

The feed or feed 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 feed or residue. The feed manifold contains the feed inlet,
It may also include a residue outlet and / or a filtrate outlet. The use of this delivery system allows increased flow rate delivery for a given inner fluid volume inside the manifold segment as compared to introducing feed at each end of the manifold segment stack. Objects can be processed. This is because the incoming incoming fluid is diverted into the interior of the two sets of manifold segments separated by the outgoing manifold.
