Abstract

A filtration module is provided, the module including at least one filtration packet containing filtration media or one or more membranes, such as a stack of membranes, the at least one filtration packet having one or more fluid ports, the one or more fluid ports being surrounded by a primary seal and a secondary seal spaced from the primary seal. The secondary seals are designed to maintain sterility of the assembly during shipping, handling and/or installation. A removable film may cover one or more fluid ports to maintain sterility prior to use.

First claim

What is claimed is:

1. A filtration module comprising at least one filtration packet containing filtration media or one or more membranes, said at least one filtration packet having one or more fluid ports, said one or more fluid ports being surrounded by a primary seal and a secondary seal spaced from said primary seal, each of said primary seal and secondary seal configured to independent seal around said one or more fluid ports; said secondary seal extending outwardly from said one or more fluid ports a greater distance than said primary seal.

2. The filtration module of claim 1 , further comprising first and second endcaps sandwiching said at least one filtration packet, said first and second endcaps comprising at least one fluid channel in fluid communication with said one or more fluid ports.

3. The filtration module of claim 2 , wherein said at least one fluid port is configured to direct fluid flow through said one or more filtration packets in a first direction, said at least one fluid channel redirects the fluid flow in a second direction different from said first direction.

4. The filtration module of claim 3 , wherein said second direction is orthogonal to said first direction.

5. The filtration module of claim 1 , further comprising a film covering said one or more fluid ports.

6. The filtration module of claim 5 , wherein said film is folded over itself so as to create a first film layer and a second film layer covering said one or more fluid ports.

7. A plurality of filtration modules, each comprising one or more filtration packets containing filtration media or one or more membranes, wherein a first of said plurality of filtration modules comprises a first fluid port, said first fluid port being surrounded by a first primary seal and a first secondary seal spaced from said first primary seal and extending outwardly from said first fluid port a greater distance than said first primary seal; a second of said plurality of filtration modules comprises a second fluid port, said second fluid port being surrounded by a second primary seal and a second secondary seal spaced from said second primary seal and extending outwardly from said second fluid port a greater distance than said second primary seal; wherein when said first and second filtration modules are engaged under pressure such that said first fluid port aligns with said second fluid port, and said first secondary seal contacts said second secondary seal to prevent contaminant ingress into said first and second fluid ports.

8. The plurality of filtration modules of claim 7 , wherein each of said one or more filtration packets and said plurality of filtration modules are sterile.

9. The plurality of filtration modules of claim 7 , wherein said first filtration module includes, prior to engaging said first and second filtration modules under pressure, a film covering said first fluid port.

10. The plurality of filtration modules of claim 9 , wherein said film is folded over itself so as to create a first film layer and a second film layer covering said first fluid port.

11. The plurality of filtration modules of claim 9 , wherein a handle is attached to the film.

12. The plurality of filtration modules of claim 7 , further comprising first and second endcaps sandwiching said plurality of filtration modules, said first and second endcaps comprising at least one fluid channel in fluid communication with said first and second fluid ports.

13. The plurality of filtration modules of claim 12 , wherein said first fluid port is configured to direct fluid flow through said one or more filtration packets in a first direction, said at least one fluid channel redirects the fluid flow in a second direction different from said first direction.

14. The filtration module of claim 13 , wherein said second direction is orthogonal to said first direction.

15. An assembly, comprising a plurality of pre-assembled, pre-sterilized filtration modules, each of said pre-sterilized filtration modules comprising at least one filtration packet containing filtration media or one or more membranes, said at least one filtration packet having one or more fluid ports, said one or more fluid ports being surrounded by a primary seal and a secondary seal spaced from said primary seal; said secondary seal extending outwardly from said one or more fluid ports a greater distance than said primary seal.

16. A plurality of filtration modules, each comprising one or more filtration packets containing filtration media or one or more membranes, wherein a first of said plurality of filtration modules comprises a first fluid port; and a spacer plate being devoid of filtration media and having a second fluid port configured and positioned to align with said first fluid port of said first filtration module when in an assembled condition; said second fluid port of the spacer plate having a gasket positioned concentrically to said second fluid port; wherein when said plurality of filtration modules and said spacer plate are engaged under pressure such that said first fluid port aligns with said second fluid port, said concentric gasket prevents contaminant ingress into said first fluid port.

17. The plurality of filtration modules of claim 16 , wherein said spacer plate has first and second opposing surfaces, and wherein said spacer plate comprises first and second radially protruding members, each extending from a respective one of said first and second opposing surfaces, each radially producing member having an annular seal.
