Abstract

The invention relates to a filtration system that includes one or more flat filter, capillary tube filter, or wound filter modules having a single or double permeate drain on the edge side and fluid couplings for connecting the filter modules to a fluid distributor or additional filter modules. The fluid couplings include at least one passage each for permeate fluid, raw fluid, and concentrate fluid.

Claims

1. A filtration system, comprising

one or more filter modules and

one or more fluid couplings for coupling the filter modules to a fluid distributor and optionally for coupling said filter modules to further filter modules, wherein

the filter modules are configured as flat filter, capillary tube filter or wound filter modules with single or double permeate outlet openings at the edges;

the fluid couplings have at least one duct for permeate fluid, and

the duct for permeate fluid is connected to the permeate outlet openings.

2. The filtration system as claimed in claim 1, wherein the fluid coupling has at least one duct for untreated fluid isolated in a fluidtight manner from the duct for permeate fluid.

3. The filtration system as claimed in claim 1, wherein the fluid coupling has at least one duct for concentrate fluid isolated in a fluidtight manner from the duct for permeate fluid.

4. The filtration system as claimed in claim 1, wherein the fluid coupling comprises a coupling body of single-piece, two-piece or three-piece design.

5. The filtration system as claimed in claim 1, wherein the fluid coupling comprises a single-piece coupling body having at least one permeate reservoir, the permeate reservoir being connected to the duct for permeate fluid and to the permeate outlet openings of the filter modules.

6. The filtration system as claimed in claim 5, wherein the single-piece coupling body comprises at least one concentrate reservoir, and the concentrate reservoir is connected to the duct for concentrate fluid.

7. The filtration system as claimed in claim 1, wherein the fluid couplings comprise seals.

8. The filtration system as claimed in claim 1, wherein the filter modules comprise one or two end walls, with at least one end wall having permeate outlet openings.

9. The filtration system as claimed in claim 8, wherein at least one end wall of the filter module has one or more ducts for permeate fluid.

10. The filtration system as claimed in claim 8, wherein at least one end wall of the filter module has one or more ducts for untreated fluid.

11. The filtration system as claimed in of claim 8 wherein at least one end wall of the filter module has one or more ducts for concentrate fluid.

12. The filtration system as claimed in claim 1, wherein the filter modules comprise a housing.

13. The filtration system as claimed in claim 12, wherein the housing of the filter modules is of tubular configuration.

14. The filtration system as claimed in claim 1, wherein the filter modules comprise one or more permeate lines.

15. The filtration system as claimed in claim 1, wherein the filter modules comprise one or more untreated fluid lines, a wall of the untreated fluid lines having outlet openings.

16. The filtration system as claimed in claim 1, wherein the filter modules are configured as spiral wound filter modules and comprise one or more flat filter elements having in each case two or three edge regions sealed in a fluidtight manner, with two of the edge regions sealed in a fluidtight manner running substantially in an axial direction between the two end sides of the filter module.

17. The filtration system as claimed in claim 16, wherein the filter modules have an active filtration surface of greater than 50 m².

18. The filtration system as claimed in claim 7, wherein the seals are annularly closed.

19. The filtration system as claimed in claim 17, wherein the filter modules have an active filtration surface of greater than 250 m².

20. The filtration system as claimed in claim 17, wherein the filter modules have an active filtration surface of greater than 1000 m².
