Classification: CPC B | IPC B

Claim 10:
11. A multi-channel crossflow filtration system, comprising:
a plurality of filtration channels;
at least one first actuator of the one or more actuators, the least one first actuator comprising the feed pump actuator to provide fluid through a feed channel to a filter of the crossflow filtration system, wherein a feed pressure sensor is provided to measure a fluid pressure in the feed channel;
at least one second actuator of the one or more actuators, the at least one second actuator comprising a retentate valve actuator to control flow of retentate fluid through a retentate channel from the filter of the crossflow filtration system, where a retentate pressure sensor is provided to measure a fluid pressure in the retentate channel;
at least one third actuator of the one or more actuators, the at least one third actuator comprising a permeate valve actuator to control flow of permeate fluid through a permeate channel from the filter of the crossflow filtration system, where a permeate pressure sensor is provided to measure a fluid pressure in the permeate channel; and
the computerized control system according to claim 3, which is adapted to:

operate at least one of the plurality of filtration channels as the forerunner filtration channel to determine the first overpressure condition from said forerunner filtration channel; and
operate at least another one of the plurality of filtration channels as the follower filtration channel to determine the at least one secondary set value for the follower filtration channel.
