Abstract

The invention relates to a filter module and a method for cleaning liquids, which ensure high performance, wherein an ultrasonic source is introduced into a filter and acts upon both the inflowing liquid and the filter itself.

Claims

AMENDED CLAIMS received at the International Bureau on 16 March 2010 (16.03.2010)

A system having filter modules for cleaning liquids, wherein a first filter module (100) comprises: a housing (10); an ultrasonic source (20); a liquid inlet (12) on the housing (10); a first outlet (14) for liquid on the housing (10); a filter (18); and a second filtered liquid outlet (16) on the housing (10); wherein the ultrasonic source (20) is disposed on a first side of the filter (18) such that ultrasound is applied to that first side of the filter (18); wherein the first outlet (14) is disposed on the first side of the filter (18); and wherein the second filtered liquid outlet (16) is disposed on a second side of the filter (18), wherein the first filter module (100) is coupled to a second filter module having an outlet and the outlet of the second filter module the second outlet (16) of the first filter module (100) is coupled such that filtered liquid from the outlet of the second filter module for backwashing the first filter module (100) via the second outlet (16) into the interior of the first filter module (100) and can be discharged via the first outlet (14).

The system of claim 1, wherein the filter (18) surrounds the ultrasound source (20).

A system according to any one of the preceding claims, wherein the inlet (12) of the filter module (100) comprises an inlet valve (72) and the first outlet (14) of the filter module (100) comprises an outlet valve (74).

4. System according to any one of the preceding claims, wherein the housing (10) has the shape of a hollow cylinder closed at its ends.

5. System according to one of the preceding claims, wherein the filter (18) has the shape of a hollow cylinder,

6. System according to claim 5, wherein the filter (18) is arranged substantially coaxially with the housing in the housing (10).

7. System according to any one of the preceding claims, wherein the ultrasonic source (20) non-coaxial with the housing (10) in the housing (10) is arranged.

A system according to any one of the preceding claims, wherein the elongated ultrasonic source (20) is offset from the longitudinal axis of the elongated housing (10) in the housing (10).

9. System according to one of the preceding claims, wherein the elongate ultrasonic source (20) parallel to the longitudinal axis of the elongated housing (10) in the housing (10) is arranged.

A system according to any one of the preceding claims, wherein the filter (18) of each filter module (100) comprises a membrane.

A system according to any one of the preceding claims, wherein the filter (IS) comprises pores of less than 1000 μm.

A system according to any one of the preceding claims, wherein the filter (18) comprises pores of less than 100 μm.

A system according to any one of the preceding claims, wherein the filter (18) comprises pores of down to 0.1 μm.

14. System according to any one of the preceding claims, wherein the filter module is adapted to filter saline water.

15. A system having filter modules (100) for purifying liquids, wherein first and second of the filter modules (100) each comprise: a housing (10); an ultrasonic source (20); a liquid inlet (12) on the housing (10); a first outlet (14) for liquid on the housing (10); a filter (18); and a second filtered liquid outlet (16) on the housing (10); wherein the ultrasonic source (20) is disposed on a first side of the filter (18) such that ultrasound is applied to that first side of the filter (18); wherein the first outlet (14) is disposed on the first side of the filter (1 S); and wherein the second filtered liquid outlet (16) is disposed on a second side of the filter (18), the second outlet (16) of the first filter module (100) being in communication with the second outlet (16) of the second filter module (100) connected, that filtered liquid of the one for backwashing the filter (18) of the other Füttermoduls (100) can be provided.
