## Abstract

A presterilizable filtration system is provided and is to be disposed of after a single use. The system has a recirculation tank and a filtration module that are connected to each other in a circuit via a hose system that can be regulated by at least one valve. The valve has a disposable separate valve part that can be integrated in the hose system and a reusable actuator.

## Claims

### Claim 1

A filtration system, comprising:
a pre-sterilized subsystem (2) that includes:
at least one disposable Container (6);
at least one disposable filtration module (7);
a disposable hose system (8) connecting the at least one container (6) and the at least one filtration module (7);
a disposable pump part (14) integrated into the hose system (8) between the at least one container (6) and the at least one filtration module (7);
a disposable, valve part (12) integrated in the hose system (8) and having a variable passage; and
a plurality of disposable measuring cells (28) integrated into the hose system (8); and
a reusable filtration installation (1) that includes:
a reusable pump drive (15) removably associated with the disposable pump part (14) for selectively operating the disposable pump part (14) to control flow through the hose system (8);
a reusable actuator (13) removably associated with the disposable valve part (12) and operating the disposable valve part (12) for selectively varying the passage of the disposable valve part (12) to control flow through the hose system (8);
reusable transducers (29) removably associated respectively with the disposable measuring cells (12); and
a controlling unit (4) connected to the reusable actuator (13), to the reusable transducers (29) and to the reusable pump drive (15) for controlling the disposable pump part (14) and for controlling the reusable actuator (13) and thereby controlling the disposable valve part (12) of the valve (11) and for receiving information from the measuring cells (28), and
wherein the at least one container (6), the at least one filtration module (7), the hose system (8), the disposable valve part (12), disposable measuring cells (28) and the disposable pump part (14) are prepackaged in a sterile manner for connection to the reusable actuator (13), the reusable pump drive (15) and the reusable transducers (29).

### Claim 2 (depends on 1)

The filtration system according to claim 1, wherein the at least one container (6) is a flexible bag.

### Claim 6 (depends on 1)

The filtration system according to claim 1, wherein the at least one container (6) is connected to the hose system (8) via a fixed connection, the hose system being configured to be cut by a welding appliance for separating the at least one container (6) from the hose system (8) in a liquid-tight manner.

### Claim 7 (depends on 1)

The filtration system according to claim 1, wherein the at least one filtration module (7) has a permeate outlet, and the hose system further comprising a permeate hose line (20) fixedly connected to the permeate outlet for delivering permeate to a permeate tank.

### Claim 8 (depends on 7)

The filtration system according to claim 7, further comprising a second a second disposable valve part (12) integrated in the permeate hose line (20) and a second reusable actuator (13) removably associated with the second disposable valve part (12), the second reusable actuator (13) being configured for operating the disposable valve part (12) for selectively varying the passage of the second disposable valve part (12) to control flow of permeate through the permeate hose line (20).

### Claim 9 (depends on 1)

The filtration system according to claim 1, wherein the at least one filtration module (7) is dead-end filtration module.

### Claim 10 (depends on 9)
